The amount of electrical energy used by the television is given by:
where P is the power of the device and t is the time.
The power of the television is P=315 W, while the total time is
If we substitute these numbers into the formula, we find the energy:
so, the correct answer is
(1) 5.67 × 10^5 J
It will be a straight horizontal line on the graph
