Embibe Experts Solutions for Exercise 1: EXERCISE

Phase difference between the instantaneous velocity and acceleration of a particle executing $\mathrm{S}.\mathrm{H}.\mathrm{M}.$ is

A particle of mass $2 \mathrm{kg},$ executing $\mathrm{SHM}$ has amplitude $20 \mathrm{cm}$ and time period $1 \mathrm{s}.$ Its maximum speed is

If length of a simple pendulum is increased by $69\%,$ then the percentage increase in its time period is

A second pendulum is moved to the moon where the acceleration due to gravity is $\frac{1}{6}$ times that of the earth, the length of the second pendulum on the moon would be, 

In case of damped oscillation frequency of oscillation is

In forced oscillations, a particle oscillates simple harmonically with frequency equal to

In case of damped oscillation amplitude of oscillation is (symbols have their usual meaning)

Resonance is special case of
