Conservation of energy with a pendulum

AI Thread Summary
The discussion centers on a pendulum's motion and the application of the law of conservation of energy. A user poses a question about where the pendulum bob will end after hitting a nail, suggesting position B as the answer. Other participants confirm that position B is indeed correct based on energy conservation principles. The conversation highlights the importance of understanding energy transformations in pendulum motion. The conclusion reinforces the correct application of physics concepts in solving the problem.

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Correct statement about a reservoir with an outlet pipe'

The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
