What is escape velocity ? Obtain an expression for it.

What is meant by relative velocity ? Write an expression for the velocity of A and B particle relative to the other moving with velocities v_ and v_ along a straight line.

Explain the meaning of kinetic energy. With examples obtain an expression for the kinetic energy of a body moving with a uniform velocity.

A short linear object is placed at a distance u along the axis of a spherical mirror of focal length f. a. Obtain an expression for the longitudinal magnification. b. Also, obtain an expression for th eration of the velocity of image (v) to the velocity of the object (u).

In a series LCR circuit, obtain an expression for the resonant frequency.

The escape velocity at the surface of Earth is approximately 8 km/s. What is the escape velocity for a planet whose radius is 4 times and whose mass is 100 times that of Earth?

The escape velocity of a particle on earth ( radius R and mass M ) is 11.2 kms^(-1) . What is the escape velocity on another planet with radius R//2 and mass M//4 ?

Explain the term 'drift velocity' of electrons in a conductor. Hence obtain the expression for the current through a conductor in terms of 'drift velocity'.

Assertion : Orbital velocity of a satellite is greater than its escape velocity. Reason : Orbit of a satellite is within the gravitational field of earth whereas escaping is beyond the gravitational field of earth.

A particle on earth's surface is given a velocity euqal to its escape velocity. Its total mechanical energy with zero potential energy reference at infinite separation will be:
