Which form of energy increases when a battery is charged?
How much energy is required to raise the temperature of 100 kg of water by 80 °C? (Use c = 4200 J/kg °C.)
Two identical bungee cords each have k = 735 N/m and are stretched 8.0 m before release. A 240 kg pod is launched upward when cords return their elastic energy (g = 9.8 N/kg). Ignoring losses, calculate the maximum height reached.
How many joules are equal to 1 kilowatt-hour (kWh)?
Which equation links specific latent heat L, energy E and mass m?
Which process transfers energy by electromagnetic waves and does not require particles or a medium?
If 40% of input energy is wasted, what fraction remains useful?
A power station has an output of 500 MW. Calculate the energy output in 3600 s. Give your answer in J.
Calculate the gravitational potential energy gained by 100 kg of water pumped to a height of 500 m (g = 9.8 N/kg).
Which energy transfer involves the movement of charged particles in a conductor?
What is the primary energy store that increases when a spring is stretched?
