Answer : Frequency equals number of oscillations in a given period of time.

Explanation :

The number of oscillations in a given period of time is known as the frequency of the wave. It is denoted by \nu. Its SI unit is hertz (Hz).

It is also defined as the inverse of time period i.e.

\nu=\dfrac{1}{T}

T is the time period.

Hence, the correct option is (B) " number of oscillations in a given period of time ".

Answer:

    K = m g (A - A2)

Explanation:

In a block spring system the total energy is the sum of the potential energy plus the kinetic energy, for maximum elongation all the energy is potential

         Em = U₀ = m g A

For when the system is at an ele

Elongation A2 less than A, energy has two parts

        Em = K + U₂

       K = Em –U₂

We substitute

     K = m g A - m gA2

    K = m g (A - A2)
