Oscillations Te...

A particle executing SHM of amplitude  cm and T=4 s, the time taken by it to move from positive extreme position to half the amplitude is

Two pendulums begin to swing simultaneously. If the ratio of the frequency of oscillations of the two is 7: 8, then the ratio of lengths of the two pendulums will be

Three masses 700 gm, 500 gm and 400 gm are suspended at the end of the spring and they are in equilibrium. When the 700 gm mass is removed, the system oscillates with a period of 3 sec, when the 500 gm mass is also removed, it will oscillate with a period of 

Periodic motion of an object or particle is known as 

A mass m oscillation with simple harmonic motion with frequency $$ f =\frac { \omega  }{ 2\pi  }  $$ and amplitude A on a spring of stiffness constant K. Which of the following is not correct?

A Particle is executing SHM with amplitude A and has a maximum velocity $$v_0$$. 
(a) At what displacement will its velocity be $$\cfrac{v_0}{2}$$ ? 
(b) What is its velocity at displacement $$A/2$$ ?

The KE and PE of a particle executing S.H.M. will be equal when displacement is:

Which of the following equation does not represent a simple harmonic motion:

Starting from the mean position a body oscillates simple harmonically with a period of  $$ 2 s.$$  After what time will its kinetic energy be  $$75 \%$$  of the total energy ?

The time period of a simple pendulum is air is $$T$$. Now the pendulum is submerged in a liquid of density $$\dfrac{\rho}{16}$$ where $$\rho$$ is density of the bob of the pendulum. The new time period of oscillation is.
