in the united states, the common system used to relate temperature to the public is the fahrenheit scale. however, the rest of the world mainly uses the scale, which is calibrated to the freezing and boiling points of water. another scale is the scale, on which zero represents a lack of atomic motion.

Answers

Answer 1

To convert between Fahrenheit and Celsius, you can use the following formulas:

°C = (°F - 32) × 5/9

°F = (°C × 9/5) + 32

. The Kelvin scale is an absolute temperature scale where zero Kelvin (0 K) represents absolute zero, the point at which all atomic motion theoretically ceases

To convert between Celsius and Kelvin, you simply add or subtract 273.15:

K = °C + 273.15

°C = K - 273.15

These conversion formulas allow you to easily convert temperatures between the Fahrenheit, Celsius, and Kelvin scales.

The United States commonly uses the Fahrenheit scale to relate temperature to the public. In this scale, the freezing point of water is 32 degrees Fahrenheit (°F) and the boiling point is 212 °F at standard atmospheric pressure.

On the other hand, the rest of the world, including most countries, uses the Celsius scale (also known as the centigrade scale) as the primary temperature scale. The Celsius scale is based on the freezing and boiling points of water. In this scale, the freezing point of water is defined as 0 degrees Celsius (°C) and the boiling point is defined as 100 °C at standard atmospheric pressure.

Another temperature scale you mentioned is the Kelvin scale. The Kelvin scale is an absolute temperature scale where zero Kelvin (0 K) represents absolute zero, the point at which all atomic motion theoretically ceases. The Kelvin scale is commonly used in scientific and engineering applications, especially in fields like physics and chemistry. The Kelvin scale has the same size units as the Celsius scale, with the difference being that the Kelvin scale starts from absolute zero.

Answers

The average acceleration of  John is 3.6 m/s.

As we know the acceleration of an object is the rate of change of its velocity concerning the time, it is a vector quantity which means it both has direction and magnitude, the orientation of the object depends on the orientation of the total force acting on the object.

As we  are given that the initial velocity, u= 0 ms/s( as it started with rest) and the time taken, t=  10 seconds,  the final velocity , v= 36 m/s.

As the formula, we can prefer the calculation of the acceleration  of an object, which is one of the equations of the motion

b.what is the speed of the plane over the ground?

Answers

The typical speed of commercial aircraft is approximately 460-575 mph, or 740-930 km/h, according to Flight Deck Friend.

How do you calculate an airplane's speed?

The amount of time needed to cover a particular distance on the ground is referred to as ground speed. For instance, when flying at cruising altitude, airplanes may have a ground speed of 300-600 knots (555-1,110 kmph). However, depending on the wind, the plane's speed over the ground may alter.

Calculation:

The aircraft must travel south at a component speed that is opposite of and equal to 80 km/h. The plane's overall speed can only be the same after that. There will be a speed of 320 kilometers per hour.

The typical speed of a commercial airplane is between 460 and 575 mph (740 to 930 km/h).

Find the center of mass of the region bounded by y=9-x^2 y=5/2x , and the z-axis. Center of Mass = __?
Note: You can earn partial credit on this problem.

Answers

The centre of mass of the region is bounded by y=9-x^2 y=5/2x, and the z-axis is (3.5, 33/8). Formulae used to find the centre of mass are as follows:x bar = (1/M)*∫∫∫x*dV, where M is the total mass of the system y bar = (1/M)*∫∫∫y*dVwhere M is the total mass of the system z bar = (1/M)*∫∫∫z*dV, where M is the total mass of the systemThe region bounded by y=9-x^2 and y=5/2x, and the z-axis is shown in the attached figure.

The two curves intersect at (-3, 15/2) and (3, 15/2). Thus, the total mass of the region is given by M = ∫∫ρ*dA, where ρ = density. We can assume ρ = 1 since no density is given.M = ∫[5/2x, 9-x^2]∫[0, x^2+5/2x]dAy bar = (1/M)*∫∫∫y*dVTherefore,y bar = (1/M)*∫[5/2x, 9-x^2]∫[0, x^2+5/2x]y*dA= (1/M)*∫[5/2x, 9-x^2]∫[0, x^2+5/2x]ydA...[1].

The limits of integration in the above equation are from 5/2x to 9-x^2 for x and from 0 to x^2+5/2x for y.To evaluate the above integral, we need to swap the order of integration. Therefore,y bar = (1/M)*∫[0, 3]∫[5/2, (9-y)^0.5]y*dxdy...[2].

The limits of integration in the above equation are from 0 to 3 for y and from 5/2 to (9-y)^0.5 for x.Substituting the values and evaluating the integral, we get y bar = (1/M)*[(9-5/2)^2/2 - (9-(15/2))^2/2]= (1/M)*(25/2)...[3].

Also, the x coordinate of the center of mass is given by,x bar = (1/M)*∫∫∫x*dVTherefore,x bar = (1/M)*∫[5/2x, 9-x^2]∫[0, x^2+5/2x]x*dA= (1/M)*∫[5/2x, 9-x^2]∫[0, x^2+5/2x]xdA...[4].

The limits of integration in the above equation are from 5/2x to 9-x^2 for x and from 0 to x^2+5/2x for y.To evaluate the above integral, we need to swap the order of integration. Therefore, x bar = (1/M)*∫[0, 3]∫[5/2, (9-y)^0.5]xy*dxdy...[5].

The limits of integration in the above equation are from 0 to 3 for y and from 5/2 to (9-y)^0.5 for x.

Substituting the values and evaluating the integral, we get x bar = (1/M)*[63/8]= (1/M)*(63/8)...[6]Thus, the centre of mass of the region is bounded by y=9-x^2 y=5/2x, and the z-axis is (3.5, 33/8).

Answers

A child sleds down a steep, snow-covered hill with an acceleration of 2.82m/s squared. if her initial speed is 0.0 m/s and her final speed is 15.5 m/s, It takes the child 5.50 seconds to travel from the top of the hill to the bottom.

We can use the following kinematic equation to solve this problem:

v^2 = u^2 + 2as

Where:

v is the final speed

u is the initial speed

a is the acceleration

s is the distance traveled

We are given u = 0.0 m/s, a = 2.82 m/s^2, and v = 15.5 m/s. We need to find s.

Rearranging the equation gives:

s = (v^2 - u^2) / (2a)

Substituting the values gives:

s = (15.5^2 - 0.0^2) / (2 x 2.82) = 74.47 m

Now, we can use another kinematic equation to find the time taken:

v = u + at

Where t is the time taken.

Substituting the values gives:

15.5 = 0.0 + 2.82t

Solving for t gives:

t = 15.5 / 2.82 = 5.50 seconds

pulsed lasers are used for science and medicine produce very brief bursts of electromagnetic energy. a) if the laser light wavelength is 1062 nm and the pulse lasts for 38 ps, how many wavelengths are found within the laser pulse? b) how brief would the pulse need to be to fit only one wavelength?

Answers

Answer:

To answer your question:

a) The formula to calculate the number of wavelengths within a laser pulse is:

number of wavelengths = pulse duration / wavelength

Plugging in the values given in the question, we get:

number of wavelengths = 38 ps / 1062 nm

Converting picoseconds to seconds and nanometers to meters, we get:

number of wavelengths = 38 x 10^-12 s / 1062 x 10^-9 m

number of wavelengths = 0.0358

Therefore, there are approximately 0.0358 wavelengths within the laser pulse.

b) To fit only one wavelength, the pulse duration would need to be equal to the wavelength. The formula to calculate the pulse duration is:

pulse duration = wavelength

Plugging in the value given in the question, we get:

pulse duration = 1062 nm

Converting nanometers to picoseconds using the speed of light ©, we get:

pulse duration = wavelength / c

pulse duration = 1062 x 10^-9 m / 3 x 10^8 m/s

pulse duration = 3.54 x 10^-12 s

Therefore, the pulse would need to be approximately 3.54 ps long to fit only one wavelength.

What is the height at the peak of the projectiles trajectory if the magnitude vo equals 42.2 meters per

Answers

Take into account that the vertical final velocity of the projectile is given by:

\(v^2_y=v^2_{oy}-2gy\)

Now, consider that at the peak of the trajectory, the vertical final velocity is zero. Moreover:

\(v^2_{oy}=v^2_o\sin ^2\theta\)

Then, by solving for y into the equation for vy^2, you obtain:

\(\begin{gathered} o=v^2_o\sin ^2\theta-2gy \\ y=\frac{v^2_o\sin \theta}{2g} \end{gathered}\)

where g = 9.8m/s^2 is the gravitational acceleration constant.

By using the given values for the angle and vo you obtain for the height of the peak y:

\(y=\frac{(42.2\frac{m}{s})(\sin 41.8)^2}{2(9.8\frac{m}{s^2})}\approx40.36m\)

Hence, the height of the peak of the projectil trajectory is approximately 40.36 m

Answers

(a) The acceleration of gravity on the planet is approximately 3.26 m/s^2.

We can use the formula for acceleration due to gravity, which is given by g = (2d) / t^2, where d is the distance fallen and t is the time taken to fall. Plugging in the values, we get g = (2 x 5.00) / 3.00^2 = 3.26 m/s^2.

(b) The mass of the planet is approximately 1.33 x 10^24 kg.

If an astronaut drops a rock from a height of 5 meters and it takes 3 seconds for the rock to hit the ground, then the acceleration due to gravity on the planet is 1.11 m/s², and the mass of the planet is 1.50x10²⁵ kg.

To solve the problem, we need to use the formula for free fall:

d = 1/2 × g × t²

where:

d = distance the rock falls

g = acceleration due to gravity

t = time it takes to fall.

We know that d = 5 meters and t = 3 seconds, so we can solve for g:

g = 2d/t²

g = 2 × 5.00m/(3.00s)²

g = 1.11 m/s²

Therefore, the acceleration due to gravity on the planet is 1.11 m/s².

To find the mass of the planet, we can use Newton's law of universal gravitation:

F = G × (m1 × m2) / r²

where:

F = the force of gravity between two objects

G = is the gravitational constant

m1 and m2 = the masses of the two objects

r = the distance between them.

We can assume that the mass of the rock is negligible compared to the mass of the planet, so we can use the force of gravity on the rock to find the mass of the planet:

F = m × g

We know that the radius of the planet is R = 2.00x10⁶ km = 2.00x10⁹ m. We can use this value to find the distance between the rock and the center of the planet:

r = R + h

where h is the height from which the rock was dropped.

We know that h = 5.00 m, so:

r = R + h

r = 2.00x10⁹ m + 5.00 m

r = 2.00x10⁹ m + 5.00 m

r = 2.00x10⁹ m

Now we can use the formula for the force of gravity to find the mass of the planet:

F = G × (m × M) / r²

m × g = G × (m × M) / r²

M = (g × r²) / G

M = (1.11 m/s² × (2.00x10⁹ m)²) / (6.67x10⁻¹¹ N m²/kg²)

M = 1.50x10²⁵ kg

Two plane metal plates 4 cm long are held horizontal 3 cm apart in a vacuum one being vertically one above other. The upper plate is at a p.d 300 volt and the lowered is earthed. Electrons having velocity of 10^7 m/s are injected horizontally midway between the plate and in a direction parallel to the 4cm edge. Calculate the vertical deflection of the electron beam as it emerges from the plates. (e/m=1.8 x 10^11Ckg^- 1).​

Answers

With Newton's second law and kinematics we find the deflection of the electron beam is y = 1.44 cm

given parameters

the voltage of each upper plate V = 300 V, the lower one zero volts the length of the plates, l = 4 cm (1 m / 100 cm) = 0.04 m the separation between the plates d = 3 cm = 0.03 m the velocity of the electrons v = 10⁷ m/s parallel to the plates the relationship e / m = 1.8 10 11 C / kg

to find

the deflection (y) of electrons

the  electric field and the electric potential are related

         V = -E d

         E = - V / d

where E is the electric field, V the electric potential and d the separation between the plates

         E = - 300 / 0.03

         E = -1 10⁴ N / C

Let's solve this exercise in parts

1st part. Let's set a reference system with the horizontal axis in direction to the length of the plates and the y axis in the vertical direction, the zero is located at the initial point of the plate and half of its separation.

Let's use Newton's second law to find the acceleration in the y-axis of the electrons

           F = m a

electric force is

           F = q E

           q E = m a

           a = q / m E

the face of electrons is negative q = -e

            a = - e / m E

            a = - 1.8 10¹¹ (- 1 10⁴)

            a = 1.8 10¹⁵ m /s²

this acceleration is directed upwards, that is, the electrons approach the positive plate.

2nd part. We use kinematics to find the time it takes for electrons to pass the plates; on the x-axis there is no acceleration, so we use the uniform motion relationships

             v = x / t

             t = x / v

             t = 0.04 / 1 10⁷

             t = 4 10⁻⁹ s

For the y-axis, let it be known that the electrons are initially in the middle between the plates, so y₀ = 0 and the velocity eg this axis is zero, we look for the deflection at the end of the plate

          y = y₀ + v_{oy) t + ½ a t²

           y = 0 + 0 + ½ a t²

           y = ½ (1.8 10¹⁵)  ( 4 10⁻⁸ )²

           y = 14.4 10⁻³ m = 1.44 10⁻² m

          y = 1.44 cm

We can use Newton's second law and kinematics to find the distance that the electron beam deviates from the middle of the plate is y = 1.44 cm, therefore the beam of electrons leaving the plates

=1/2  eE/m  (x/v)^2

=1/2 (e/m)  V/d  (x/v)^2

=1/2×1.8×〖10〗^11×300/0.03×(0.04/〖10〗^7 )^2

⸫ y=1.44×〖10〗^(-2)  m

Hence, the vertical deflection of the beam of an electron beam is 1.44×〖10〗^(-2)  m.

A ball released from rest on an elevated ramp uniformly accelerates at a rate of 3.52 m/s2 for 23.3m. what is the final speed of the ball?

Answers

The final speed of the ball when it accelerate uniformly at a rate of 3.52 m/s² for 23.3 m is 12.81 m/s.

What is speed?

Speed can be defined as the ratio of distance to time.

The S.I unit of speed is m/s.

To calculate the final speed of the ball, we use the formula below.

Formula:

v² = u²+2as........... Equation 1

Where:

v = Final speedu = Initial speeda = accelerations = distance.

From the question,

Given:

u = 0 m/s from resta = 3.52 m/s²s = 23.3 m

Substitute these values into equation 1

v² = 0²+2×3.52×23.3v² = 164.032v = √(164.032)v = 12.81 m/s.

Hence, the final speed of the ball is 12.81 m/s.

Why do we use logarithmic scale to describe the range of the sound intensities we hear?

Answers

The logarithmic scale is used to describe the range of sound intensities we hear because it allows us to represent a wide range of values in a more manageable and intuitive way.


Sound intensities can vary over a very large range, from the faintest sounds we can perceive to extremely loud ones. The logarithmic scale compresses this range into a more compact representation by using logarithms.

When we use a logarithmic scale, each unit increase on the scale corresponds to a multiplication by a fixed factor. In the case of sound intensity, we use the decibel (dB) scale, which is logarithmic.

The decibel scale is based on the logarithm of the ratio of the sound intensity being measured to a reference intensity. This reference intensity is the quietest sound that the average human ear can hear, which is approximately 1 picowatt per square meter (pW/m^2).

By using a logarithmic scale, we can represent a wide range of sound intensities from barely audible sounds to extremely loud ones. For example, if we have a sound that is 10 times louder than the reference intensity, it would be represented as 10 dB. If the sound is 100 times louder, it would be represented as 20 dB, and so on.

Using a logarithmic scale allows us to easily compare and understand the relative loudness of different sounds. It also helps us to perceive changes in sound intensity more accurately.

An object is moving to the right at a constant velocity. What will happen if a force of 20 n starts acting on it in the opposite direction?.

Answers

If an object is moving with a constant velocity and the force of 20 newton is applied on the object then the object will first slow down then comes to rest for a moment and finally it will accelerate into the opposite direction of its motion.

According to the first law of motion proposed by Newton,

If an object is in a state of rest or in a state of motion it will continue to stay in it state until and unless and external force comes into play and changes the state of the motion.

If an object is moving with a constant velocity it means that there is no net external force working on the object.

If the external force of 20 Newton start acting on the object in the opposite direction. This force will first slow down the speed of the object, and after moment really coming into the state of rest the object will start to accelerate in the opposite direction because of the action of the external force of 20N.

consider two objects, object A and object B. Suppose that object A is charged and object B is uncharged. can you tell from this information whether or not either object is a conductor or insulater?

Answers

It is not possible to conclusively determine whether object A or object B is a conductor or insulator. A charged object can be either a conductor or an insulator, as both can hold a charge. Similarly, an uncharged object could also be a conductor or insulator, as its current state does not provide enough information about its material properties.

To determine whether object A or object B is a conductor or an insulator, additional information about the materials they are made of is needed. If object A is made of a metal, it is likely a conductor, while if it is made of a non-metal, it may be an insulator. Similarly, if object B is made of a metal, it is likely a conductor, while if it is made of a non-metal, it may be an insulator.

In summary, the fact that object A is charged and object B is uncharged does not provide enough information to determine whether either object is a conductor or an insulator. Additional information about the materials they are made of is needed to make this determination.

Which of the following products will have elastic demand (alcohol, gasoline, travel souvenirs, cigarettes)

Answers

The product among alcohol, gasoline, travel souvenirs, cigarettes that will have elastic demand is cigarettes.

What is elastic demand?

Elastic demand refers to a situation in which a change in the price of a good or service results in a more significant change in the amount demanded. When the percentage change in quantity demanded is greater than the percentage change in price, the demand for the product is said to be elastic.

When the quantity demanded of a product decreases significantly when the price rises, the demand for the product is said to be elastic. Similarly, when a slight change in price causes a significant change in quantity demanded, the demand is said to be elastic. Conversely, if a product's price increases by a small percentage, and the demand for the product decreases by a smaller percentage, the demand for the product is said to be inelastic.

Cigarettes, of all the products listed above, are likely to have an elastic demand.

This is because smokers who are addicted to cigarettes are more likely to quit smoking or reduce their consumption in response to an increase in the price of cigarettes compared to the other goods.

Thus, a slight increase in the price of cigarettes is likely to cause a significant decrease in the number of cigarettes consumed.

La fórmula: P = W/t  ó  W = P x t. donde:

P = potencia

W = trabajo

t = tiempo

Otra fórmula de potencia es: P= I x V

Proceso de carga de un capacitor - condensador

Una fórmula muy importante que también hay que tener en cuenta es: V = q/C que indica que el voltaje es proporcional a la carga que hay en un condensador.

De la fórmula de potencia P= I x V y considerando que la corriente es constante (corriente continua), entonces la potencia es proporcional al voltaje.  Si el voltaje aumenta en forma lineal, la potencia aumentará igual. Ver el siguiente diagrama.

Como la potencia varía en función del tiempo, no se puede aplicar la fórmula W = P x t, para calcular la energía transferida. Pero observando el gráfico, se ve que esta energía se puede determinar midiendo el área bajo la curva de la figura.

Energía Almacenada en un Condensador - Capacitor

 

El área bajo la curva es igual a la mitad de la potencia en el momento “t”, multiplicada por “t”.

Entonces: W = (P x t) / 2. Pero se sabe que P = V x I. Si se reemplaza esta última fórmula en la anterior se obtiene: W = (V x I x t) / 2, y como I x t = CV = Q, entonces para saber cuanta energía (W) hay en un condensador usamos una de las siguientes fórmulas:

W = (CV2/2) julios

W = (QV/2) julios

W  = (Q2/2C) julios

, donde:

W = Trabajo (Energía) en julios

C = Capacidad en faradios

V = voltaje en voltios en los extremos del condensador

Q = carga del condensador

Answer with the given explanations below: First the given formula that looks like this is: or where:

P = power

W = work

t = time

Next with another given power formula that looks like this is:

This is the charging process of a capacitor - capacitor #1.

Then it's a very important given formula that it must also be taken into account is: which it was indicated that the voltage is proportional to the charge on a capacitor.

In the following below, from the given power formula that looks like this is: and we are considering that the current is the constant (direct current), and then the power is proportional to the voltage. If the voltage increases linearly, the power will increase the same. See the following diagram. (I'm sorry, Yhungbabe, I don't have the diagram to show you in order to refer to the total energy stored in the capacitor because I havenèt learned the energy stored in the capacitor)

Anyway, since the power varies as a function of the time, the given formula that looks like this is: cannot be applied to calculate the energy transferred. But looking at the graph, it seems that this energy can also be determined by measuring the area under the curve of the figure.

This is The Energy Stored in a Capacitor - Capacitor #2.

The area under the curve is equal to the half of the power at time "t", being multiplied by "t".

Then with the given formula below that looks like this is:

But it's known that If this is the last given formula is being replaced in the previous one, we obtain the new given formula that looks like this is: and as another new given formula that looks like this is: there's so to find out how much energy (W) that there's in a capacitor that we use in one of the new given formulas that looks like in the listed below are:

joules

joules

joules  

Now finally where:

W = Work (In The Energy) in Joules

C = Capacity in the farads

V = voltage in the volts at the ends of the capacitor

Q = a capacitor charge
