Question
How many joules of energy does a $100-$ watt light bulb use per hour? How fast would a 70 -kg person have to run to have that amount of kinetic energy?
Step 1
The energy consumed by an electrical appliance is given by the formula: \[E = P \times t\] where \(E\) is the energy, \(P\) is the power of the appliance, and \(t\) is the time for which the appliance runs. Show more…
