What effect occurs on the frequency of a pendulum if it is taken from the earth surface to deep into a mine
In deep mine $$g' =g\left(1-\dfrac {d}{R}\right)$$,
i.e., $$g$$ decreases with depth.
so $$n\propto \sqrt g$$, frequency also decreases.
A thin uniform vertical rod of mass $$m$$ and length $$l$$ pivoted at point $$O$$ is shown in the figure. The combined stiffness of the spring is equal to $$k$$. The mass of the spring is negligible. The frequency of small oscillation is:
A particle executing simple harmonic motion of amplitude 5 cm has maximum speed of 31.4 cm/s. The frequency of its oscillation is :
The unit 'hertz' is same as.
