When you put a string on a hook, and hold it on an angle
ie: .

and then u want to know the angle in which you let go:

^---------this is the angle in which you choose the amplitude-this one is around 10 degrees

Does the time period of oscillation depend on the displacement from the equilibrium position?
As long as angular amplitude is kept small, the period does not depend on the angular amplitude of the oscillation. It is simply dependent on the weight. It should be noted that to some extent period actually does depend on the angular amplitude and if it gets too large, the effect will become noticeable.
What happens to the intensity of a wave if the amplitude decreases?
Intensity of a wave is proportional to the frequency squared and amplitude squared based on this formula; I=1/2pw^2A^2V where p is the density of the medium, w is the angular frequency and A is the amplitude and V is the wave velocity. So, everything else remaining constant, decreasing the amplitude will decrease a waves intensity. Example decreasing the the amplitude by a factor of 4 will decrease the wave intensity by a factor of 8.
What is the difference between angular velocity and angular momentum?
angular momentum and angular velocity
How do you find the velocity of a mass at half the amplitude?
Seems it is related to simple harmonic oscillation The expression for velocity v = w ./ (a2 - x2) Plug x = a/2. and get the required v. w is the angular frequency
What is Difference between angular velocity and angular speed?
Angular velocity is a vector with a direction and angular speed is a scalar with no direction.

What is a difference between frequency and angular frequency?
Frequency is a metric for expressing the rate of oscillation in a wave. For planar and longitudinal waves, this often expressed in oscillations-per-second or Hz. Angular frequency used for expressing rates of rotation, similar to revolutions-per-second, and is usually expressed in radians-per-second. It can be thought of as a wave with a constant amplitude where the amplitude rotates in a circle in space. The two differ by factor of 2*Pi. Omega (angular frequency) = 2*Pi*f(frequency in Hz)
How does a pendulums period vary with the length of its mass With Gravitational acceleration?
The length of the pendulum is measured from the pendulum's point of suspension to the center of mass of its bob. Its amplitude is the string's angular displacement from its vertical or its equilibrium position.

angular momentum is the measure of angular motion in a body.
A sound waves amplitude corresponds to the sounds what?
Usually, people are asking as if there is just "the" amplitude in sound waves in air. The loudness perception of a sound is determined by the amplitude of the sound waves − the higher the amplitude, the louder the sound. Which amplitude of sound (sound amplitude) do you mean? There are: amplitude of particle displacement ξ, or displacement amplitude amplitude of sound pressure p or pressure amplitude amplitude of sound particle velocity v, or particle velocity amplitude amplitude of pressure gradient Δ p, or pressure gradient amplitude. Furthermore, think of the amplitude of the oscillation of a string. The maximum magnitude of the deflection of a wave is called amplitude. Look at link: "What is an amplitude?"
How are the amplitudes of sound waves?
There is not only "one" amplitude. There is an amplitude of particle displacement ξ, or displacement amplitude, an amplitude of sound pressure p or pressure amplitude, an amplitude of sound particle velocity v, or particle velocity amplitude, an amplitude of pressure gradient Δ p, or pressure gradient amplitude. If the "sound" inceases, the "amplitude" also increases.
Can uniform angular velocity has acceleration?
No, uniform angular velocity means no angular acceleration.
Define angular impulse?
Angular impulse is defined as the rate-of-change of the angular acceleration.
