Question

time period of a spring pendulum when a lift moves downwards with constant velocity V in time T. when the lift moves upward with a constant acceleration g÷3. The time period is​

Answer 1

Explanation:

If the time period T of vibration of a liquid drop depends on surface tension ( (S), ) radius ( (r) ) of the drop and density. ( (rho) ) of the liquid, then the expression of ( T ) is. (a) ( T=k sqrt{rho r^{3} / S} )
