The mathematical relationship between the velocity of sound, its wavelength, and its frequency is represented by the equation v = fλ, where v is the velocity of the sound, f is the frequency of the sound, and λ is the wavelength of the sound.

Velocity is a measure of how quickly something is moving in a given direction. It is a vector quantity, meaning it has both magnitude and direction. Velocity is typically expressed in units of distance per unit of time, such as meters per second (m/s). Velocity is a measure of how quickly an object is changing its position relative to its surroundings.

This equation is known as the wave equation and is a fundamental concept in physics. It states that the velocity of a wave is equal to the product of its frequency and wavelength.

if Ezra reduced the length of the rope to 0.25 meters and  rotational speed is held constant, There is a change of 3.14 m/sec in the velocity when length of rope is reduced from 0.50 to 0.25 m.

The no. of revolutions made by a rotating object in a given defined time is termed as rotational speed.

Given:

initially length of rope i.e. R = 0.50m

2 rotations per second = 1 rotation =0.5 sec= T

now after changing ropes length R=0.25 m

Initially velocity of the ball rotating on R =0.50m

⇒v=2πR/T

⇒v=2*3.14*0.50/0.5

⇒v=6.28 m/sec

6.28 m/sec is the velocity of the ball rotating on R =0.50m.

Now to find the velocity of the ball rotating on R =0.25m we use the following eq.

⇒v=2πR/T

⇒v=2*3.14*0.25/0.5

⇒v=3.14 m/sec

3.14 m/sec is the velocity of the ball rotating on R =0.25m

Hence, there is a change of 3.14 m/sec in the velocity when length of rope is reduced from 0.50 to 0.25 m.

The ratio of the mass of the objects which are hung in the vertical spring is 9

The frequency of the spring with mass m₁ = 12 Hz

The frequency of the spring with the mass m₂ = 4 Hz

The ratio of the mass can be found using the formula,

                    [tex]\displaystyle f = \frac{1}{2 \pi} \sqrt{\frac{k}{m} }[/tex]

where f is the frequency of the spring

         k is the spring constant

The formula to calculate speed of emitted photoelectron is KE = 1/2mv²

The process through which electrons leave a metal's surface after absorbing electromagnetic radiation is known as the photoelectric effect.

Since photons are the units of light, according to Einstein's theory, when a photon collides with a metal's surface, the full photon's energy is transferred to the electron. A portion of this energy is utilized to free the electron from the metal atom's hold, while the remainder is transferred as kinetic energy to the ejected electron.

Three crucial aspects of the photoelectric effect are not explicable by classical physics: (1) the lack of a lag time; (2) the independence of the photoelectrons' kinetic energy from the strength of the incident radiation; and (3) the presence of a cut-off frequency.

(a) The car travels a distance of 147 m before it overtakes the truck.

(b) At the moment when car overtakes the truck, the speed of car was 21 m/s

Let us assume that the time taken by the car to overtake the truck = t seconds

Now calculating the distance travelled by car and truck during this time,

Using the kinematic equation for calculating the distance travelled by car and the truck:

The distance travelled can be computed by the relationship [tex]s= 0.5at^2[/tex]

Distance travelled by car will be [tex]S_{car} =0.5 \times 6\times t^2=3t^2 \:m[/tex]

Distance travelled by truck will be [tex]S_{truck}=21 \times t = 21t \:m[/tex]

At the instant of overtaking

Distance travelled by car = Distance travelled by truck

[tex]3t^2 = 21t\Rightarrow t = \frac{21t}{3t}=7\:sec.[/tex]

So, the distance travelled by car before it overtakes will be 3*7*7 = 147 m

The velocity of a body change from vi to 30m/s in 20econd if the rate of change of velocity is 4m/s, initial velocity is -50 m/s.

To find the initial velocity, vi, of a body that undergoes a change in velocity, you can use the formula:

vi = vf - at

where vi is the initial velocity, vf is the final velocity, a is the acceleration (rate of change of velocity), and t is the time over which the acceleration occurs.

In this case, you are given that the final velocity is 30 m/s, the acceleration is 4 m/s^2, and the time is 20 seconds. Plugging these values into the formula gives:

vi = 30 m/s - 4 m/s^2 * 20 s

vi = 30 m/s - 80 m/s

vi = -50 m/s

Yes, the damping coefficient of a spring-cart system independent of mass. Mass doesn't affect the damping coefficient (since that is assumed constant).

Damping coefficient - The system’s damping coefficient is a measure of how quickly it returns to rest as the frictional force dissipates its oscillation energy.

Damping is experienced by most oscillatory systems such as harmonic oscillators. These systems, when displaced from their equilibrium position, experience a restoring force proportional to their displacement. If a frictional force proportional to the velocity is also applied, the system exhibits damped harmonic oscillation. In a damping phenomenon, the amplitude of the oscillation is decreasing gradually instead of sudden decreasing. When there is a damping in the system then the amplitude decreases and the period increases.

So, We can see that mass will absolutely affect the damping ratio, but not the damping coefficient (since that is assumed constant).

Answer:

It is renewable.

Explanation:

The gravity of the earth is infinite and so it is renewable energy.

Gravitational potential energy is neither renewable nor non-renewable as it is a form of energy that exists due to the position of an object in a gravitational field. It is a type of potential energy that is associated with an object's position in a gravitational field and its mass. The amount of gravitational potential energy an object has depends on its mass, height above the reference level, and the strength of the gravitational field.

Renewable and non-renewable energy sources refer to the sources of energy that are used to generate electricity or power and are consumed over time. Examples of renewable energy sources include solar, wind, and hydropower, while non-renewable energy sources include fossil fuels such as coal, oil, and natural gas.

Therefore, gravitational potential energy is not considered a renewable or non-renewable energy source as it is not a source of energy that is harvested or consumed. Rather, it is a property of an object that can be converted into other forms of energy such as kinetic energy when the object falls or is released from its position in a gravitational field.
