Symmetry of the laws of nature with respect to translation in time give increase to-

A simple harmonic motion is  x(t)=sin²ωt−2cos²ωt. The angular frequency of oscillation is given by?

An oscillator is producing FM waves of frequency 2kHz with avariation of 10kHz. The modulating index=?

A ball lying on the ground does not move on its own only the reason is-

The equation of motion of a particle is x = acos(αt)². Motion?

The time period of a pendulum clock is:

The displacement of a particle is represented by the equation y = sin³(ωt). Then the motion is-

There is  not an oscillatory motion-

A simple harmonic motion is represented by \(y=5(\sin 3 \pi t+\sqrt{3} \cos 3 \pi t) \mathrm{cm}\) The amplitude and time period of the motion are :

When a body is at rest, it follows-

A thin spherical shell of mass M and radius R has a small hole. A particle of mass m is librated  at its mouth. Then

"The motion of a particle with a restoring force gives oscillatory motion". so forces which can be a restoring force for the oscillatory motion is-

which of the following does not show oscillatory motion?

In a simple harmonic motion, the correct statement is-

Simple harmonic motion (SHM) is a technical term used to describe a certain kind of idealized oscillation. Practically all the oscillations that one can see directly in the natural world are much more complicated than SHM. Why then do physicists make such a big deal out of studying SHM?
