When velocity of a body increases, its acceleration is

The distance of the body from mean position, where the kinetic energy of a particle perfonning S.H.M. of amplitude 8 mm, is three times its potential energy is

A bubble of a gas released at the bottom of a lake increases to eight times its original volume when it reaches the surface. Assuming that atmospheric pressure is equivalent to the pressure exerted by a column of water 10m height, the depth of the lake is "____________" .

If the body is moving in a circle of radius r with a constant speed v , its angular velocity is

When the angular velocity of a unit uniformly rotating body becomes 3 times its original value, the resultant of forces applied to it increase by 60N. Find the acceleration of the body m= 3kg.

Solve the following examples / numerical problems: If the body is moving at 100 m/s on the earth's surface , what will be its (i) Kinetic energy (ii) total energy ?

A particle is performing linear S.H.M.at a point A, on the path , its potential energy is three times kinetic energy . At another point B on the same path, its kinetic energy is 3 times the potential energy. The ratio of the kinetic energy at A to its kinetic energy at B is
