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
