To calculate the energy used in drying your hair, we need to first convert the time from minutes to hours:
15 minutes = 15/60 hours = 0.25 hours
Next, we can use the formula:
Energy = Power x Time
Energy = 1.200 kW x 0.25 hours = 0.3 kWh
Therefore, 0.3 kilowatt-hours (kWh) of energy is used in drying your hair.
if it takes 15 minutes to dry your hair with a 1.200 kW Hair dryer, how much energy is used in drying your hair?
