The answer is 175184.08 joules
Answer:
R = 60 Ω
Explanation:
given,
Potential of the certain device, V = 120 V
current rating of the circuit, I = 20 A
resistance of the device, R = ?
Using Ohm's Law
V = I R
R = 60 Ω
hence, the resistance of the device is equal to 60 Ω
It’s called conservation of energy. The system (the rider) can’t randomly gain energy without something else giving it energy because energy can’t be created or destroyed, only transferred. The pendulum example is beyond popular and you see physics professors doing it all the time. I think your teacher wants you to say it’ll continue forever, but I don’t think it will. The system will most likely lose energy to its surroundings. And there’s things like air resistance which will, overtime, slow it down. So no, it won’t go on forever
Tidal power is the only form of energy which derives directly from the relative motions of the Earth–Moon system, and to a lesser extent from the Earth–Sun system
