A particle of mass m moving with speed v undergoes a perfectly elastic collision with an identical stationary particle. After the collision, the first particle moves at an angle of 30° to its original direction. The angle between the velocity vectors of the two particles after collision is:

A body of mass m moves in a circle of radius r with uniform speed v. The centripetal force is:

A particle executes simple harmonic motion with amplitude 0.10 m and frequency 10 Hz. Its maximum speed during the oscillation is:

A transformer steps up the voltage by a factor of 100. If the primary current is 5 A and the transformer is ideal, the secondary current is:

A concave mirror of focal length f produces a real image that is 3 times the size of the object. The object distance is:

A transformer works on the principle of:

A body starts from rest with uniform acceleration of 5 m/s². The distance travelled in 5 seconds is:

In an adiabatic process:
