Question

please answer this q. who are smart in science​

Answer 1

Answer:

kinetic energy = 1/2mv²

power = work/elapsed time= W/Δt

Heat energy = msΔT ( here m is mass of substance, s is specific heat , and T is change in temp)

current = V/R ( ohms law)

1 kilowatt hour is the energy produced by 1 kilowatt  power source in 1 hour.

1kWh=1kW×1hour=1000×3600W.s

⟹1kWh=3.6×106  J

⟹1kWh=3.6MJ
