Correct answer: A. P = dE/dv
- A. P = dE/dv
- B. P = dE/dt
- C. P = dv/dt
- D. P = (dE/dv) (dE/dt)

About Work and Energy
Work transfers energy when a force causes displacement, while kinetic energy, gravitational potential energy and power describe motion, position and the rate of energy transfer. The work-energy theorem links net work with change in kinetic energy, and efficiency accounts for energy losses rather than treating them as energy destruction.

An overhead tank of capacity 1000 litres has to be filled in 1/2 an hour using a water pump. The tank is kept at a height 10m above ground and the water level is 10m below ground. The opening of the inlet pipe inside the tank is 1.11cm2. Assuming the efficiency of the motor to be 60%, the electric power used is (Neglect viscosity):
A tube closed at one end and containing air produces, when excited, the fundamental note of frequency 512Hz. If the tube is open at both ends, the fundamental frequency that can be excited is (in Hz):
The first resonance length in a closed pipe is 20 cm then second resonance occurs at
Force acting on a particle moving in a straight line varies with the velocity of the particle as F=K/V. Here K is constant. The work done by this force in time t is:
A particle of mass 0.5 kg is displaced from position r1→ (2,3,1) to r2→(4, 3, 2) by applying a force of magnitude 30 N which is acting along (iˆ+ jˆ+kˆ). The work done by the force is:
The potential energy of a particle of mass 5kg moving in the x-y plane is given by, U (-7+24y)J where x and y are in metre. If the particle starts from rest from the origin, then the speed of the particle at t = 2s is:
