Solving Simple Power Problem: Grandfather Clock + 3.70kg Weight

Click For Summary
To calculate the power delivered by the 3.70 kg weight of the grandfather clock, first determine the gravitational potential energy using the formula E = mgh, where m is the mass, g is the acceleration due to gravity (approximately 9.81 m/s²), and h is the height (0.700 m). The energy calculated is then divided by the time duration of 3.00 days, converted into seconds, to find the power. The formula for power is P = E/t, which simplifies the calculation. The discussion emphasizes understanding the relationship between energy, time, and power in this context.

A grandfather clock is powered by the descent of a 3.70 kg weight.
If the weight descends through a distance of 0.700 m in 3.00 days, how much power does it deliver to the clock?

I have tried this a million times, but I'm just having a mental block.
If someone could please help me out & explain how to do this, I'd be super grateful!

Thank you so much!

power is energy/time

The energy is the gravitational energy of the weight

Thread 'Correct statement about size of wire to produce larger extension'

The answer is (B) but I don't really understand why. Based on formula of Young Modulus: $$x=\frac{FL}{AE}$$ The second wire made of the same material so it means they have same Young Modulus. Larger extension means larger value of ##x## so to get larger value of ##x## we can increase ##F## and ##L## and decrease ##A## I am not sure whether there is change in ##F## for first and second wire so I will just assume ##F## does not change. It leaves (B) and (C) as possible options so why is (C)...
