A particle at the end of a spring executes simple harmonic motion with a period t_(1) , while the corresponding period for another spring is t_(2) . If the period of oscillation with the two springs in series is T, then prove that t_(1)^(2)+t_(2)^(2)=T^(2)

A spherical liquid drop is placed on a horizontal plane. A small disturbance causes the volume of the drop to oscillate. The time period of oscillation (T) of the liquid drop depends on radius (r ) of the drop density ( rho ) and surface tension (s) of the liquid. Which among the following will we be a possible expression for T (where k is a dimensionless constant )?

The errors in the measurement of the effective length ( l ) and the time period (T) of a pendulum executing simple harmonic motion are 1% and 2% respectively. Estimate the error in the determination of acceleration due to gravity (g) using this pendulum. Given the relation among the relevant quantities, T = 2pi sqrt((l)/(g)).
