Homework Statement
if error was found out to be plus/minus 58 and observed value was 227.32 how should the data be rounded of( to which significant figure)

AI Thread Summary
The discussion centers on how to round the observed value of 227.32 given an error of ±58. It emphasizes that the number of significant figures should reflect the accuracy of the measuring instrument used. If the value is derived from a question, the significant figures should match those present in the original data. The rounding process should consider both the observed value and the associated error. Proper rounding ensures accurate representation of the data's precision.
Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears.
My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it.
I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height.
But the...
Here is what I tried
This question was actually asked in one of our engineering entrances.
The answer was 1D.
My teachers say that we have to use μₘ/fₘ to get to this answer. I cannot understand why. I'll be really glad if you could tell me the exact definition of power (numerically) that works in all scenarios.
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...
