If 40% of the energy stored in the water is wasted, what is the useful energy (in kJ) from 33 600 kJ?
Which method transfers energy without needing particles to move (can travel through a vacuum)?
A spark transfers 0.60 J and 2.0 µC of charge. What potential difference (V) produced this spark?
Which equation links energy (E), power (P) and time (t)?
Which equation links momentum p, mass m and velocity v?
Which equation links power P, potential difference V and current I?
A toy airplane is launched by a spring with k = 50 N/m, extension 0.12 m and mass 0.020 kg. Using energy conservation (½ k x^2 ? ½ m v^2) what is the maximum speed just after launch (m/s)?
