| August 9, 2021 | education
The power of the device can be calculated using the formula:
P = A / t, where P is the required power of the device (W), A is the useful work performed by the device (A = 2400 J), t is the operating time of the device (t = 120 s).
Let’s calculate the power of the device:
P = A / t = 2400/120 = 20 W.
Answer: The power of the device is 20 W.
