AI Thread Summary
To determine the speed of the new steamship, a scientist proposes measuring the time taken for the steamship to travel from point A to point B and back, denoted as t1 and t2, respectively. The distance between points A and B is represented as S, and the angle between line AB and the steamship's direction is noted as alpha. The discussion invites participants to provide solutions, emphasizing the importance of showing work for clarity. The goal is to calculate the steamship's speed based on the provided parameters. Engaging in this problem-solving approach can foster collaborative learning and understanding of the underlying physics concepts.

in order to find out the speed of a new steamship,a scientist comes up with a idea to slove it:He makes the steamship sail from A to B and then return to A from B(look at the image). only when the angle between the line AB and the direction of the sreamship is a,the streamship can sail though the line AB,and the time it takes is t1. and the time of coming back though BA is t2. the distance of AB is S. question:what is the speed of the new streamship?

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

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...
