The ratio of the times required to travel along the outer edge and along the inner edge of a circular path by a bicycle is 20 : 19. If the path between the edges be of breadth 5m, then find the diameter of the inner circle.

There is a path around a circular garden. The outer circumference of that path is 912 m and the inner circumference is 868 m. Find the breadth of the path.

The radius of the earth = R. if a geostationary satellite is revolving along a circular path at an altitude of 6R above the surface of the earth, what will be the time period of revolution of another satellite revolving around the earth at an altitude of 2.5R ?

A car is moving along a circular path of radius 20 m with a speed of 40 km cdot h^(-1) . Find its angular velocity.

An aeroplane is travelling at the speed of 360 km//hr along the horizontal to the earth surface'. What is the induced potential developed between the ends of th'e wing 5 m long, if the earth’s magnetic field at the location has-a magnitude of 4 xx 10^-4 wb//m^2 and dip angle is 30^@ ?

Two satellites A and B are revolving along circular paths of the same radius. The mass of A is 16 times the mass of B. The ratio of the time period of revolution of B to that of A is
