The input is chemical energy (in the form of fuel). The outputs areSound (not useful)Kinetic (useful)Heat (may be useful)The efficieny is given by useful output energy divided by total input (or output) e...
(draw diagram on whiteboard) As the potential difference increases, the current increases, since V=IR (where V is the potential difference, I is the current and R is the resistance). Initially the current...
Initially the average kinetic energy of the trapped air within the can is much higher the surrounding body of air. However, when immersed in the cold water, there is a significant decrease in the average ...
The work done by a force on a particle is: Work done = Force x Displacement.The energy of a particle is given by the sum of its potential and kinetic energies.As the particle does not gain or lose any hei...
