Question

The momentum of a student with a cycle is 400kg m/s. cycle is moving with a velocity of 5m/s find the mass of the student and the cycle

Answer 1

Sensitivity of potentiometer can be increased by. Sensitivity of potentiometer can be increased by increasing the length of the potentiometer wire and by reducing the current in the circuit by using a rheostat. Both the methods help in decreasing the potential gradient, and thereby increasing the resistivity.
