A person goes to bed at shasrp 10.00 pm every day. Is it an example of periodic motion? If yes, what is the time period? If no why?

What is periodic motion? Give its examples.

Two towns A and B are connected by a regular bus service with a bus leaving in either direction every T minutes. A man cycling with a speed of 20 km h^(-1) in the direction A to B notices that a bus goes past him every 18 min in the direction of his motion, and every 6 min in the opposite direction. What is the period T of the bus service and with what speed (assumed constant) do the buses ply on the road ?

The bob of a simple pendulum execute simple harmonic motion in water with a period t , while the period of oscillation of the bob is t_(0) in air. Negleting frictional force of water and given that the density of the bob is (4//3)xx1000 kg//m^(3) . What relationship between t and t_(0) is true.

A point performs simple harmonic oscillation of period T and the equation of motion is given by x= a sin(omega t+(pi)/(6)) . After the elapse of what fraction of the time period, the velocity of the point will be equal to half of its maximum velocity?

If two persons sitting on a swing instead of one, why the periodic time does not changed?

A mass m is attached with rods as shown in figure. This mass is slightly stretched and released whether the motion of mass is S.H.M. if yes then find out the time period.

Two simple harmonic motions are represented by y_(1) = 10 sin"" (pi)/(4) (12t+1)" and " y_(2) = 5(sin"" 3pi t+ sqrt(3) cos 3pi t) . Find out the ratio of their amplitudes. What are the time period of two motions.

In one of the satellites of Jupiter has an orbital period of 1.769 days and the radius of the orbit is 4.22 xx 10^8 m. Show that the mass of Jupiter is about one-thousandth that of the sun.
