Explanation:

Answer:

17.15 m/s²

Explanation:

The formula for force is ;

F= m*a   where m is mass of object 1 and a is acceleration due to gravity

The force, F , used in pulling the mass is ;

4.9 * 9.8 =48.02 N

Applying the formula for force to get acceleration

F= m*a

48.02 = 2.8 * a

a= 48.02 / 2.8

a= 17.15 m/s²

A graph is a visual depiction of statistical data or a logical relationship between variables. Graphs serve a predictive purpose because they have the virtue of displaying broad trends in the mathematical behavior of data. However, as just approximations, they may be incorrect and occasionally deceptive.

Most graphs have two axes, with the axis denoting a set of independent variables and the vertical axis denoting a set of dependent variables. The most typical graph is indeed a broken-line chart, where the regression coefficient is typically a factor of duration.

An IC engines means an Internal Combustion engine. Here, the combustion takes place in side a chamber or a cylinder internally, hence it is known as internal combustion engine.

Combustion is the process where oxygen reacts with the fuel and it burns to produce a large amount of force and heat. In each revolution of the crank, the engine creates a power stroke when the piston goes from the bottom dead center to the top dead center.

During each power stroke, the energy released forces the piston down and the crankshaft is rotated.

Answer:

Approximately \(69\; {\rm N}\) at approximately \(126^{\circ}\).

Explanation:

Assume that both angles in the question are relative to the positive \(x\)-axis (towards the positive horizontal direction.)

Horizontal component (\(x\)-component) of the two forces would be:

Note that the \(x\)-component of the \(90\; {\rm N}\) force is negative since this components points away from the positive \(x\!\)-direction.

Hence, the net force in the \(x\)-component would be:

\((50\; {\rm N}) \, \cos(30^{\circ}) + (90\; {\rm N}) \, \cos(160^{\circ}) \approx (-41.3) \; {\rm N}\).

(Again, this component is negative since it points away from the positive \(x\)-axis.)

Similarly, the vertical component (\(y\)-component) of the two forces would be:

Hence, the net force in the \(y\)-component would be:

\((50\; {\rm N}) \, \sin(30^{\circ}) + (90\; {\rm N}) \, \sin(160^{\circ}) \approx 55.8\; {\rm N}\).

Refer to the diagram attached. The resultant net force is the vector sum of the components. Apply the Pythagorean Theorem to find this net force:

\(\begin{aligned}(\text{net force}) &= \sqrt{(\text{$x$-component})^{2} + (\text{$y$-component})^{2}} \\ &\approx \sqrt{(-41.3)^{2} + (55.8)^{2})}\; {\rm N} \\ &\approx 69\; {\rm N}\end{aligned}\).

Find the angle of this net force relative to the positive \(x\)-axis using the inverse cosine function \(\arccos\):

\(\begin{aligned}\arccos\left(\frac{(\text{$y$-component})}{(\text{net force})}\right) &\approx \arccos\left(\frac{55.8\; {\rm N}}{69\; {\rm N}}\right) \\ &\approx 126^{\circ}\end{aligned}\).

The maximum value of capacitance C1, when capacitor C2 is chosen as 200 nF, is not constrained or limited, and it can be any value greater than or equal to zero in nanofarads (nF).

To determine the maximum value of capacitance (C1) when capacitor C2 is chosen as 200 nF, we need to consider the total equivalent capacitance in the circuit.

The given circuit diagram is not provided in the question, so I'll provide a general approach based on the assumption that capacitors C1 and C2 are connected in parallel.

When capacitors are connected in parallel, the total equivalent capacitance (C_eq) is calculated by summing the individual capacitance values:

C_eq = C1 + C2

Since C2 is given as 200 nF, we can express the equation as:

C_eq = C1 + 200 nF

However, the maximum value of C1 is not specified in the question. If we assume that there are no other constraints or limitations, we can simply state that the maximum value of C1 can be any value greater than or equal to zero.

Therefore, the maximum value of capacitance C1, when capacitor C2 is chosen as 200 nF, is not constrained or limited, and it can be any value greater than or equal to zero in nanofarads (nF).

1. Amplitude Modulation

Explanation:

AM is an acronym for Amplitude Modulation and it's refers to a process that is typically used for coding sounds such as voices and music for transmission from one point to another.

On the other hand, FM is an acronym for frequency modulation used for the propagation and transmission of sound waves.

Basically, the two forms of modulation are used for broadcasting in radio transmission.

Electromagnetic waves is a propagating medium used in all communications device to transmit data (messages) from the device of the sender to the device of the receiver.

Generally, the most commonly used electromagnetic wave technology in telecommunications is radio waves.

Radio waves can be defined as an electromagnetic wave that has its frequency ranging from 30 GHz to 300 GHz and its wavelength between 1mm and 3000m. Therefore, radio waves are a series of repetitive valleys and peaks that are typically characterized of having the longest wavelength in the electromagnetic spectrum.

Using the equations of kinematics, we obtain the following results;

The maximum height is the height that was attained by the projectile. In this case, we have the fact that the projectile was fired vertically upwards with a speed of 34.0m/s. On the descent, the cannonball lands on top of a 30.0m tall building.

1) The maximum height could be obtained from;

v^2 = u^2 -2gh

v = final velocity ( 0 m/s at the maximum height)

u = initial velocity = 34.0m/s

g = acceleration due to gravity = 9.8 m/s^2

h = maximum height attained

Since v = 0 m/s

u^2 = 2gh

h = u^2/2g

h = (34)^2/ 2 * 9.8

h = 1156/19.6

h = 59 m

2) Given that the distance covered from the maximum height to the top of the building = 59 m - 30 m = 29 m

v^2 = u^2 + 2gh

In this case, the initial velocity is zero because the cannonballs dropped from a height

v^2 = 2gh

v = √2gh

v = √2 * 9.8 * 29

v = 24 m/s

Given that;

v = u - gt

v = 0 m/s when the cannon ball is projected upwards;

u = gt

t = u/g

t = 34.0m/s/9.8 m/s^2

t = 3.5 secs

The total time spent in air = 2(3.5 secs) = 7 secs

Since it varies directly with the square of the wire's diameter and inversely with wire length, the conductance of a wire is 0.15 mho.

A wire's electrical resistance varies inversely as the square of its diameter and directly as its length. A wire with a diameter of 1/4 inch and a length of 200 inches has a 20 ohm resistance.

Let L be the wire's length, d its diameter, and C its conductance be the parameters.

Based on the facts provided, we can:

C ∝ d² (conductance varies directly as the square of the diameter)

C ∝ 1/L (conductance varies inversely as the length)

Combining these two proportionalities, we get: C ∝ d²/L

This connection can be used to find a solution to the issue. Using the numbers for the 50 m wire, we can first calculate the proportionality constant as follows:

C = k(d²/L)

0.12 = k(2²/50)

k = 0.12*50/4 = 1.5

So, using this value of k, we can determine the conductance of a 75 m wire with a 2.5 mm diameter:

C = k(d²/L)

C = 1.5*(2.5²/75)

C = 0.15 mho

Answer:

The amount of heat needed to heat  2 kilograms of water from 24.0°C to 100.0°C to make a cup of tea is (C) 640,000 J.

Explanation:

How to calculate the amount of heat needed?

        Q = m s Δ t

        where Q = the amount of heat needed

        m = mass of the substance being heated

        s = specific heat of the substance being heated

        and Δ t = the difference between the final and initial temperatures.

It is given that 2 kilograms of water are to be heated from 24.0°C to 100.0°C to make a cup of tea and the specific heat of water is 4186 J/kg°C.

Therefore,

Putting these values in the equation Q = m s Δ t we find,

Q = 2 x 4186 x 76 J

    = 636272 J

    ≈ 640,000 J.

Thus the amount of heat needed to heat  2 kilograms of water from 24.0°C to 100.0°C to make a cup of tea is (C) 640,000 J.
