Calculate the kinetic energy of an electron of mass \(8 \times 10^{-32}\)kg and velocity \(5 \times 10^6 \text m \text s^{-1}\).
What is the meaning of gravitational potential energy?
The diagram shows a lift.
The maximum load that the lift can carry is 2020 kg to a height of 45 m.
Calculate the power of the lift if the time taken to reach 45 m height is 2 minutes?
Which of the following form of energy can be found in a moving car?
There is something wrong with this question.
