A clock draws 2.0 watts of power to operate and is in operation 8,600 hours per year. The energy usage of the clock, in kWh per year, is closest to

Respuesta :

Answer:

the energy usage of the clock per year is 17.2 kWh

Explanation:

Given;

power drawn by the clock, P = 2 W

duration of the clock's operation, t = 8,600 hours per year

The energy usage of the clock per year is calculated as;

E = Pt

[tex]E = (\frac{2}{1000} )kW \ \times \ 8,600 \ hr\\\\E = 17.2 \ kWh[/tex]

Therefore, the energy usage of the clock per year is 17.2 kWh
