Answer:

GET GOOD

Explanation:

The frequency of the vibrations caused by the crevices in the tire tread pattern, when the car moves at 29.2 m/s, is approximately 1945 Hz.

To determine the frequency of the vibrations caused by the crevices in the tire tread pattern, we need to first calculate the time it takes for the tire to move over a distance equivalent to one crevice, and then calculate the frequency based on that time.

The distance between crevices is given as 1.50 cm, which is equivalent to 0.015 m (since 1 cm = 0.01 m). The speed of the car is given as 29.2 m/s.

To find the time it takes for the tire to move over a distance of one crevice, we can use the formula:

Time = Distance / Speed

Time = 0.015 m / 29.2 m/s

Now, to find the frequency (f), we use the formula:

Frequency = 1 / Time

Frequency = 1 / (0.015 m / 29.2 m/s)

Frequency = 1945 Hz

Therefore, the frequency of the vibrations caused by the crevices in the tire tread pattern, when the car moves at 29.2 m/s, is approximately 1945 Hz.

Let's determine the type of waves that interact with each other to make nodes and antinodes when the string in a violin vibrates.

Sanding waves can be said to be a combination of two waves which move in opposite direction. Each of the waves have the same frequency and amplitude.

These waves interact with each other.

They are also called stationary waves.

They make nodes and antinodes which are found where the wave forms.

Therefore, when the string in a violin vibrates, the waves which interact with each other to form nodes and antinodes can be classified as standing waves.

ANSWER:

Standing waves.

This is due to the fact that when kinetic energy is doubled, the speed of the block increases by the square root of 2, resulting in an increase of 40% in the velocity.

Kinetic energy is the energy of motion. It is the energy that an object has because of its motion. Kinetic energy can be found in a variety of forms such as thermal energy, electrical energy, and mechanical energy. Kinetic energy can be converted into other forms of energy such as potential energy. Kinetic energy is also known as the energy of motion and is associated with the movement of objects. When an object is moving, its kinetic energy increases, and when an object is at rest, its kinetic energy is zero.

Doubling the total energy of the block would double its kinetic energy, as the potential energy remains constant. Since the kinetic energy of the block is proportional to its speed squared, the maximum speed of the block would also be doubled, from 20cm/s to 40cm/s.

Answer:

F = 45000 [N]

Explanation:

To solve this problem we must use Newton's second law, which tells us that the sum of forces on a body is equal to the product of mass by acceleration.

ΣF = m*a

Where:

F = force [N] (units of Newtons)

m = mass = 30000 [kg]

a = acceleration = 1.5 [m/s²]

\(F = 30000*1.5\\F = 45000 [N]\)

The theoretical efficiency is greater than that of the actual efficiency of the engine. This is because heat engine always produces some waste heat.

The Second Law of Thermodynamics states that a heat engine cannot be 100% efficient. In practice, a heat engine is only 100% efficient when it is operating at about 30-50% efficiency.

If we were to multiply this by 100, we would get the efficiency as a percent: 49%. This is the theoretical maximum efficiency. If we were to actually build an engine, it would be less efficient than the theoretical engine. The theoretical engine that can achieve this theoretical maximum efficiency is called the Carnot Engine.

The two general ways to increase the internal energy of a substance, as stated by the first law of thermodynamics, are through heat transfer (Q) and work done (W).

According to the first law of thermodynamics, the change in internal energy (ΔU) of a system is equal to the heat transferred to the system (Q) minus the work done by the system (W).

Mathematically, it can be expressed as ΔU = Q - W.

1. Heat transfer (Q): Heat can be transferred to a substance, increasing its internal energy. Heat transfer can occur through conduction, convection, or radiation. For example, if a substance is heated by placing it on a hot stove, heat is transferred to the substance, leading to an increase in its internal energy.

2. Work done (W): Work can be done on a substance, causing an increase in its internal energy. This can be achieved through mechanical processes such as compression or expansion. For instance, when a gas is compressed, work is done on the gas, increasing its internal energy.

Therefore, the first law of thermodynamics allows for increasing the internal energy of a substance either by transferring heat to it or by doing work on it.

Answer:

  F = 4361.7 N

Explanation:

In this exercise the force of the string is asked, to solve it we use Newton's second law

          F - W = m a

force is the tension of the rope

the centripetal acceleration is

        a = v² / r

the angular and linear speed are related

Wave velocity is sometimes also called the propagation velocity or propagation speed because the disturbance propagates from one location to another. Consider the periodic water wave in Figure 13.7. Its wavelength is the distance from crest to crest or from trough to trough.

Explanation:

The mass of a baseball is too large to exhibit wave-like behavior, making the wave nature of matter insignificant.

The wave nature of matter is not important for a baseball because the mass of a baseball is too large to exhibit wave-like behavior.

According to the de Broglie equation, the wavelength of an object is inversely proportional to its mass. Since a baseball has a large mass, its wavelength is incredibly small and insignificant.

Additionally, wave-like behavior is only observable on the atomic and subatomic level, where particles have incredibly small masses.

Therefore, for macroscopic objects like a baseball, classical mechanics is a more appropriate way to describe its motion, and the wave nature of matter can be ignored.

A brake is applied to a spinning wheel, initially moving counterclockwise, causing it to slow down with a constant angular acceleration of magnitude 5.40 rad/s2. Immediately after the brake is applied, the wheel rotates through 50.4 rad during a 4.00 s time interval. The angular speed (in rad/s) of the wheel at the end of this time interval is: 21.6 rad/s

The angular speed of the wheel at the end of the 4.00 s time interval can be calculated by using the equation for angular acceleration,

\(ω = ω0 + αt.\)

In this case, the initial angular speed of the wheel is 0 rad/s since it was at rest when the brake was applied, and the angular acceleration is 5.40 rad/s2.  

This gives us the equation\(ω = 0 + 5.40t.\)

Substituting the time of 4.00 s, we get \(ω = 5.40(4.00) = 21.6 rad/s.\)

This is the angular speed of the wheel at the end of the 4.00 s time interval. This can also be determined by using the equation for the change in angular displacement, \(Δθ = ω0t + ½αt2.\)

In this case, the initial angular displacement of the wheel is 0 rad and the angular acceleration is 5.40 rad/s2. This gives us the equation

\(Δθ = 0 + ½(5.40)(4.002) = 43.2 rad.\)

Since the wheel rotated through 50.4 rad during the 4.00 s time interval, the angular speed must be \(ω = Δθ/t = 50.4/4.00 = 12.6 rad/s.\)

The angular speed of the wheel at the end of the 4.00 s time interval is 21.6 rad/s, due to the constant angular acceleration of magnitude 5.40 rad/s2. The angular speed can also be determined by using the equation for the change in angular displacement, which gives 12.6 rad/s.

average velocity = 35 m/s

Required

total distance before it broke down

Solution

Average velocity : total displacement : total time

Can be formulated

avg velocity = Δx : Δt

Input the value :

Δx=avg velocity x Δt

Δx = 35 m/s x 80 s

Δx = 2800 m

In addition, if we are asking for velocity, we must know the starting and ending points (displacement)

But if we calculate the total distance, what is written is the average speed

avg speed = total distance : total time

The electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.

To find the electric field strength at a distance 1.20 m on the x-axis, we can use Coulomb's law:

\($$F=k\frac{q_1q_2}{r^2}$$\)

where F is the force between two charges, q1 and q2 are the magnitudes of the charges, r is the distance between the charges, and k is the Coulomb constant.For a single point charge q located at the origin of the x-axis, the electric field E at a distance r is given by:

\($$E=\frac{kq}{r^2}$$\)  where k is the Coulomb constant.

So, let's calculate the electric field due to each charge separately and then add them up:

For the +2.0 C charge at x = 0, the electric field at a distance of 1.20 m is:\($$E_1=\frac{kq_1}{r^2}=\frac{(9\times10^9)(2.0)}{(1.2)^2}N/C$$\)

For the -3.0 C charge at x = 0.40 m, the electric field at a distance of 1.20 m is:

\($$E_2=\frac{kq_2}{r^2}\)

\(=\frac{(9\times10^9)(-3.0)}{(1.20-0.40)^2}N/C$$\)

The negative sign indicates that the direction of the electric field is opposite to that of the positive charge at x = 0.

To find the net electric field, we add the two electric fields\(:$$E_{net}=E_1+E_2$$\)

Substituting the values of E1 and E2:

\($$E_{net}=\frac{(9\times10^9)(2.0)}{(1.2)^2}-\frac{(9\times10^9)(3.0)}{(0.8)^2}N/C$$E\)

net comes out to be -1.5×10⁴ N/C.

Therefore, the electric field strength at a distance of 1.20 m on the x-axis is -1.5 × 10⁴ N/C.
