Question

Suppose you have a 100-watt light bulb that you leave turned on for one minute. How much energy does it use?

Answer 1

The energy that 100-watt light bulb consume when is turned for one minute is 1.667 J, Joules are the units of energy or work

Step-by-step explanation:

The relation between the power and the energy we have to know the units of each

`power= (kg*m^(2) )/(s^(3) ) \\ energy = (kg*m^(2) )/(s^(2) ) \\\\energy=(power)/(time) \\energy=(100 W)/(1 min)*(1 min)/(60s) \\ energy= (100 W)/(60s)\\ energy=1.6667 J`

The energy in one minute is 1.667 Joules
