Oscillatory Motion

Select the correct statements. (i) A simple harmonic motion is necessarily periodic (ii) A simple harmonic motion is necessarily oscillatory (iii) An oscillatory motion is necessarily periodic (iv) A periodic motion is necessarily oscillatory

STATEMENT-1 : If a body is floacting submerged,then on pressing, it will execute damped oscillatory motion. and STATEMENT-2 : When a body is floating fully submerged and displaced from its position , then no net force acts at its position.

If the differential equation given by (d^(2)y)/(dt^(2))+2k(dy)/(dt)+omega^(2)y=F_(0)sin pi t describes the oscillatory motion of body in a dissipative medium under the influence of a periodic force, then the state of maximum amplitude of the oscillation is a measure of

A loosely wound helix made of stiff metal wire is mounted vertically with the lower end just touching the mercury in a dish. When the current from a batter is started in the metal wire through the mercury, the wire executes oscillatory motion with the lower end jumping out of and into the mercury. Explain.

For the harmonic travelling wave y=2cos2pi(10t-0.0080x+3.5) where x and y ar in cm and t is in second. What is the phase diffference between the oscillatory motion at two points separated by a distance of

A particle of mass 2g is initially displaced through 2cm and then released. The frictional force constant due to air on it is 12 xx 10^(-3)N//m . The restoring force constant is 50 xx 10^(-3)N//m . If it is in oscillatory motion, its time period is
