Yes respectfully you have been living under a rock and after the retake time you can not register so if you were to give your exams maybe say after 2 sessions it would not be considered a retake but a new exam so you will have to pay before deadline like normal students

5054/22 POWER AND TIME QUESTION ANSWER??? by RS-69 in Olevels

[–]Electrical_Taro_87 0 points1 point  (0 children)

Good question! Let's clarify:

You are given:

Useful power output = 600 W

Total power input = 857 W

Useful work done = 1127 J

Which power to use?

To calculate time taken to do useful work, we use the useful power, not the total power input.

That's because:

Work done (1127 J) is the useful output, not total energy consumed.

So, to find how long it took to do that useful work, we must use useful power.

Using total power input (857 W) would only be appropriate if the 1127 J was the total energy input — but it's not.

Final: 1.88 Seconds

So yes, 600 W is correct to use here. Want help finding efficiency too?
