Introduction:
Simple harmonic oscillator is any system which when displaced from its equilibrium position, exhibits a restoring force where restoring force is directly proportional to the displacement.
The time period in the simple harmonic oscillator is the time taken to complete full oscillation.
Write the expression for the time period of the simple harmonic oscillator.
Here,
Conclusion:
The time period of a simple harmonic oscillator does not depend on the amplitude. Thus, the statement is not correct.

Explanation of Solution
Write the expression for the time period of the simple harmonic oscillator.
The frequency in the simple harmonic oscillator is inversely proportional to the time period.
Here,
Substitute
Thus, the frequency of the simple harmonic oscillator does not depend on amplitude, it depends on two factors one is mass and the other is force constant.
Conclusion:
The frequency of the simple harmonic oscillator does not depend on the amplitude. Thus, the statement is correct.
(c)
Whether the statement is true or false.
(c)

Explanation of Solution
The condition for the simple harmonic oscillator is that force should be directly proportional to the displacement and the displaced object tends to move in its equilibrium position. The restoring force always acts in the direction opposite to the particle displacement. For any system to be simple harmonic the acceleration of the particle is in the opposite direction from its equilibrium position and acceleration should be proportional to the displacement from the equilibrium position.
Conclusion:
The net force in the particle is one-dimensional motion which is directly proportional to the displacement made by the particle from its equilibrium position. Thus, the statement is correct.

- The figure below shows, at left, a solid disk of radius R = 0.600 m and mass 75.0 kg. Tu Mounted directly to it and coaxial with it is a pulley with a much smaller mass and a radius of r = 0.230 m. The disk and pulley assembly are on a frictionless axle. A belt is wrapped around the pulley and connected to an electric motor as shown on the right. The turning motor gives the disk and pulley a clockwise angular acceleration of 1.67 rad/s². The tension T in the upper (taut) segment of the belt is 145 N.

You replace the belt with a different one (one slightly longer and looser, but still tight enough that it does not sag). You again turn on the motor so that the disk accelerates clockwise.
