AI Thread Summary
To read a stopwatch quickly, start by noting that the small dial indicates minutes. If the small hand is not in the red section, add the seconds from the black numbers; if it is in the red section, use the red numbers instead. The big hand shows the seconds, while the lines on the dial represent the tens of seconds. Understanding these basics allows for efficient reading of the stopwatch. Mastering this technique can significantly enhance timing accuracy.

You really couldn't figure this out yourself?

The small dial tells you the number of minutes. Then, if the small hand is not in a red section, you add the number of seconds by reading the black numbers, otherwise the red numbers, for the big hand. The lines then indicate the tens of seconds.

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...
