A small creature moves with constant speed in a vertical circle on a bright day. Does its shadow formed by the sun on horizontal plane move in a simple harmonic motion?

A body moving with a constant speed v in a circle of radius r. its angular acceleration is :

A body is moving with a constant speed v in a circle of radius r. its angualr acceleration is :

An electron moves with a constant speed v along a circle of radius r.(a) find the equivalent current through a point on its path.(b) Find the magnetic moment of the circulating electron.(c ) Find the ratio of the magnetic moment to the angular momentum of the electron.

An ideal gas enclosed in a vertical cylindrical container supports a freely moving piston of mass M. the piston and the cylinder have equal cross sectional area A. when the piston is in equilibrium, the volume of the gas is V_(0) and its pressure is P_(0) . the piston is slightly displaced from the equilibrium posittion and released. assuming that the system is completely isolated from its surrounding, the piston executes a simple harmonic motion with frequency

A motorcycle has to move with a consatnt speed on an overbridge which is in the form of as circular arc of radius R and has a total length L. Suppose the motorcycle starts from the highest point. a) what can its maximum velocity be for which the contact with the road is not broken at the highest point? b) If the motorcycle goes at speed 1/sqrt2 times the maximum found in part a. where will it lose the contact with the road? c) What maximum uniform speed can it maintain on the bridge if it does not lose contact anywhere on the bridge?

A simple pendulum of length l is suspended from the ceilling of a car moving with a speed v on a circular horizontal road of radius r. a. Find the tension in the string when it is at rest with respect to the car. b.Find the time period of small oscillation.

A small block of mass 100 g moves wth uniform speed n a horizontal circular groove, with vertical side walls, of radisu 25 cm.If the block takes 2.0 s to complete ne round, find the normal contact force by tehside wall of the groove.

One end of string of length L is connected to a particle of mass 'm' and the other end is connected to small peg on a smooth horizontal table.If the particle moves in circle with speed 'v'. te net force on the particle (directed towards centre ) will be (T represents the tension in thestring)
