Finding Kinetic energy with given weight 10kg

In classical mechanics, kinetic energy (KE) is equal to half of an object's mass (1/2*m) multiplied by the velocity squared. For example, if a an object with a mass of 10 kg (m = 10 kg) is moving at a velocity of 5 meters per second (v = 5 m/s), the kinetic energy is equal to 125 Joules, or (1/2 * 10 kg) * 5 m/s 2.

Answer:

Correct 40 m/s

Explanation:

Because conductors are made of materials that permit charges to circulate freely throughout their structure, the electric field inside one is zero. Charges inside a conductor will redistribute themselves when an electric field is applied, resulting in a zero electric field inside the conductor.

Electrostatic equilibrium is produced when the charges in a conductor move in a way that cancels the electric field. As the electric field is not zero and is perpendicular to the surface, any excess charge on a conductor will be located there. This "Faraday cage effect" is what gives conductors their ability to shelter electrical equipment from outside electric fields.

The stationary listener hears the sound at a frequency of approximately 6.05 kHz as the plane approaches.

A stationary listener hears the sound from the aeroplane at a different frequency due to the Doppler effect. To calculate the frequency heard by the listener, we can use the formula:
f' = f * (c + Vr) / (c + Vs)

where f' is the observed frequency, f is the emitted frequency (4.03 kHz), c is the speed of sound (343 m/s), Vr is the speed of the listener (0 m/s, as they are stationary), and Vs is the speed of the source (the airplane, -114 m/s since it's approaching).
f' = 4.03 kHz * (343 + 0) / (343 - 114)
f' ≈ 4.03 kHz * 343 / 229
f' ≈ 6.05 kHz.

Answer:

The acceleration that the jet liner that must have is 2.241 meters per square second.

Explanation:

Let suppose that the jet liner accelerates uniformly. From statement we know the initial (\(v_{o}\)) and final speeds (\(v_{f}\)), measured in meters per second, of the aircraft and likewise the runway length (\(d\)), measured in meters. The following kinematic equation is used to calculate the minimum acceleration needed (\(a\)), measured in meters per square second:

\(a = \frac{v_{f}^{2}-v_{o}^{2}}{2\cdot d}\)

If we know that \(v_{o} = 0\,\frac{m}{s}\), \(v_{f} = 82\,\frac{m}{s}\) and \(d = 1500\,m\), then the acceleration that the jet must have is:

\(a = \frac{\left(82\,\frac{m}{s} \right)^{2}-\left(0\,\frac{m}{s} \right)^{2}}{2\cdot (1500\,m)}\)

\(a = 2.241\,\frac{m}{s^{2}}\)

The acceleration that the jet liner that must have is 2.241 meters per square second.

Explanation:

The solar nebula became hot and dense because of that it pulling in more gas. This flattened into a rotating disk. It  spun  faster and faster, forming the Sun. This order did the events forming our solar system occur.

In the so-called nebular hypothesis of the genesis of the solar system, the Sun and planets originated by condensation from a gaseous cloud. In 1734, Swedish philosopher Emanuel Swedenborg claimed that the planets arose from a nebular crust that enveloped the Sun before breaking apart. Immanuel Kant, a German philosopher, proposed in 1755 that the Sun and planets were created by a slow rotating nebula that was eventually pushed together by its own gravitational force and flattened into a spinning disc. In 1796, the French astronomer and mathematician Pierre-Simon Laplace presented a similar concept, but with the planets forming before the Sun. The Kant-Laplace theories were criticised by the British physicist James Clerk in the late nineteenth century.

8. A) When the size of a milk chocolate bar is reduced to 5.000 g, the amount of sugar in milligrams is approximately 73.15 mg.

b) The percentage of sugar in a 14.630 g milk chocolate bar is approximately 63.60%.

10 A) 4.1 ounces of a steroid ointment is approximately 120 grams.

D) Each blueberry high-fiber muffin contains approximately 24 grams of dietary fiber.

1. Ranking the quantities in decreasing order of distance:

1 Mm (Megameter) --> 1 km (Kilometer) --> 100 m (Meter) --> 50 mm (Millimeter) --> 1 cm (Centimeter) --> 1 mm (Millimeter) --> 5 million nm (Nanometer)

2. a). To find the amount of sugar in milligrams when the size of the milk chocolate bar is reduced to 5.000 g, we can use the proportion:

14.630 g / x = 5.000 g / 1000 mg

Solving for x, we get:

x = (5.000 g * 14.630 g) / 1000 mg ≈ 73.15 mg

So, when the chocolate bar size is reduced, the amount of sugar in milligrams will be approximately 73.15 mg.

b). To calculate the percentage of sugar in a 14.630 g milk chocolate bar, we use the formula:

Percentage = (Amount of sugar / Total weight) * 100

Percentage = (9.315 g / 14.630 g) * 100 ≈ 63.60%

So, the percentage of sugar in a 14.630 g milk chocolate bar is approximately 63.60%.

10. a). To convert 4.1 ounces of a steroid ointment to grams, we use the conversion factor:

1 lb = 16 oz, 1 lb ≈ 453.592 g

4.1 oz * (1 lb / 16 oz) * 453.592 g ≈ 119.0792 g ≈ 120 g (to two significant figures)

So, the pharmacist needs to prepare approximately 120 grams of ointment.

D). If blueberry high-fiber muffins contain 51% dietary fiber and a package weighing 16 oz contains six muffins, we can calculate the amount of fiber in each muffin as follows:

Amount of fiber per muffin = (Weight of one muffin * Percentage of dietary fiber) / 100

Amount of fiber per muffin = (16 oz / 6) * (51 / 100) * 28.3495 g ≈ 24 g (to two significant figures)

Each blueberry high-fiber muffin contains approximately 24 grams of dietary fiber.

Answer:

If you haven't heard, Joe Biden would like to unite America.

It was a focus of the Democrat's campaign. It's even the theme of Biden's inauguration — "America United."

The inaugural committee says the slogan "reflects the beginning of a new national journey that restores the soul of America, brings the country together, and creates a path to a brighter future."

If only it were that easy.

When Biden is sworn in at 12:01 p.m. ET Wednesday as the 46th president of the United States, it will be with the understanding that the country is as divided as it's ever been, as pessimistic as it's been in three decades and facing health, economic and racial crises.

Temperature (F) at 8 AM 99.3 98.8 97.6 97.7 97.1

Temperature (°F) at 12 AM 99.1 99.2 97.8 972 97.4

Let the temperature at 8 AM be the first sample, and the temperature at 12 AM be the second sample. Then,

d = x₂ - x₁

Now, we need to find the values of d for all five subjects.

Therefore, d is as follows:

d₁ = 99.3 - 99.1

   = 0.2

d₂ = 98.8 - 99.2

    = -0.4

d₃ = 97.6 - 97.8

    = -0.2

d₄ = 97.7 - 97.2

   = 0.5

d₅ = 97.1 - 97.4

    = -0.3

In general, Hd represents the mean of all values of d.

Thus, the value of Hd is:

Hd = (0.2 + -0.4 + -0.2 + 0.5 + -0.3) / 5

(1) The particles in a liquid are arranged in a way that they are in contact with each other, but they are able to slip past one another. option is C.

(2) The phase change that occurs when a solid changes directly into a gas is called sublimation. option is D.

In a liquid, the particles are closely packed together and are in contact with each other.

However, they are not as tightly packed as they are in a solid. The particles in a liquid have enough energy to move around and slide past one another, but they are still attracted to each other through intermolecular forces.

This is why a liquid has a definite volume but takes the shape of its container, as the particles can move around and fill the space available.

Solid to gas phase change:

When a solid changes directly into a gas, without passing through the liquid state, this is called sublimation.

In this process, the particles in the solid gain enough energy to break free from the intermolecular forces holding them together, and they transition directly to the gas phase. This can occur when the pressure of the surrounding environment is low and the temperature is high enough to provide the necessary energy for sublimation to occur.

This molar mass suggests that the gas sample is likely a compound made up of a single element, such as a noble gas. One possibility is that the gas sample is argon, which has a molar mass of approximately 39.9 g/mol. Alternatively, the gas sample could be krypton, which has a molar mass of approximately 83.8 g/mol.

Molar mass is a term used in chemistry to refer to the mass of a substance in grams per mole. It is defined as the mass of a substance divided by the number of moles of that substance. The molar mass of a substance is often used to convert between mass and moles, or to calculate the mass of a substance required to react with another substance in a chemical reaction.

To identify the gas sample, you can use the ideal gas law, which states that the pressure of a gas is directly proportional to its temperature and the number of moles of the gas, and inversely proportional to the volume it occupies.

The ideal gas law is given by the following equation:

PV = nRT

where P is the pressure of the gas in pascals, V is the volume of the gas in liters, n is the number of moles of the gas, R is the universal gas constant, and T is the temperature of the gas in kelvins.

Using the values provided in the question, we can solve for the number of moles of the gas:

n = (PV)/(RT)

= (790 torr * 1.365 L) / (8.314 J/mol*K * 368 K)

= 0.0478 moles

Since the mass of the gas sample is 3.33 grams and the number of moles is 0.0478 moles, we can use the molar mass of the gas to identify it. The molar mass is given by the following equation:

M = m/n

where M is the molar mass in grams per mole, m is the mass of the gas in grams, and n is the number of moles of the gas.

Solving for the molar mass, we get:

M = 3.33 g / 0.0478 moles

The angle between the transmission axes of the two Polaroid sheets is approximately 59.5 degrees. This calculation is based on Malus's law and the given intensity relationship between the light emerging from the second sheet and the light incident on the first sheet.

When unpolarized light passes through a Polaroid sheet, it becomes polarized, meaning its electric field vectors vibrate in a particular direction.

The intensity of light passing through a Polaroid sheet is given by Malus's law:

I = I0 * cos^2(θ)

Where I is the transmitted intensity, I0 is the incident intensity, and θ is the angle between the transmission axis of the Polaroid sheet and the polarization direction of the incident light.

In this problem, we have two Polaroid sheets. Let's denote the angle between the transmission axis of the first sheet and the polarization direction of the incident light as θ1, and the angle between the transmission axis of the second sheet and the polarization direction of the light transmitted through the first sheet as θ2.

Given that the intensity of the light emerging from the second sheet is 41.1% of the intensity of the light incident on the first sheet, we can write the equation:

I2 = 0.411 * I1

Applying Malus's law to each sheet, we have:

I1 = I0 * cos^2(θ1)

I2 = I1 * cos^2(θ2)

Substituting the value of I1 into the second equation, we get:

I2 = (I0 * cos^2(θ1)) * cos^2(θ2)

0.411 * I1 = (I0 * cos^2(θ1)) * cos^2(θ2)

Dividing both sides of the equation by I0 * cos^2(θ1), we have:

0.411 = cos^2(θ2)

Taking the square root of both sides, we get:

√0.411 = cos(θ2)

Solving for θ2, we find:

θ2 ≈ arccos(√0.411)

θ2 ≈ 59.5 degrees

the angle between the transmission axes of the two Polaroid sheets is approximately 59.5 degrees.

Part(a) The equation for the loop is 0 −1−(R1 +R2)I2+(R3+R2)I3=0

Part(b) The current through the bottom branch 13 is 0.75 A.

(a) This equation is found by applying the loop rule, which states that the sum of voltage drops around a loop is equal to zero. To find the equation, we start at the point, and move clockwise around the loop. At each point, we add the voltage drop of the component connected between that point and the previous point. We then substitute the component values into the equation.

For example, the voltage drop across R1 is equal to I2 * R1. In this equation, I2 and I3 are the currents through R2 and R3 respectively.

(b) To calculate this, we need to use Ohm's Law, which states that the voltage across a resistor is equal to the current through the resistor multiplied by the resistance.

First, we need to calculate the total resistance of the circuit.

       R total = R_1 + (1/2)*R_2 + R_3

                    = 0.5 + (1/2)*2.5 + 0.5

                    = 2.5 Ω

Now, we can use Ohm's Law to calculate the current through the bottom branch.

             I 13 = V/R

                     = (12-0.5)/2.5

                     = 0.75 A

Therefore, the current through the bottom branch 13 is 0.75 A.
