The earth revolves round the sun in one year. If distance between then becomes double the new period will be ……. years.

A freely falling stone crashes through a horizontal glass plate at time t and losses half of its velocity. After time it fills on the ground. The glass plate is 60 m high from the ground Find the total distance traveled by the stone.

Particle A is projected vertically upward from a top of a tower. At the same time particle B is dropped from the same point. The graph of distance (s) between the two particle varies with time is.

The period of revolution of planet  A around the sun is 8 times that of B. The distance of A from the sun is how many times greater than that of B from the sun.

Let  and  A vector   is such that 

We can solve simultaneous equations as we feel easy for us. There are not any particular steps to be followed. We just have to solve the equation to find the values of the variables. We try to eliminate the variables using addition and subtraction to single out single variable.

The earth E moves in an elliptical orbit with the sun s at one of the foci as shown in figure. Its speed of motion will be maximum at a point…..

Given graph shows relation between position (X)→ time (t) Find the correct graph of velocity → time

Here are displacement time graphs of particle A and B .if and are velocities of the particles respectively, then =……

Which part shows initial velocity of the particle?

A satellite of mass m is circulating around the earth with constant angular velocity. If radius of the orbit is RO and mass of earth M, the angular momentum about the center of earth is,

If , then
