    Confused
AI Thread Summary
The discussion centers on the confusion regarding the phrase "A is a factor of 3 above B." Participants clarify that typically, this means A equals B multiplied by 3, not 4. The conversation emphasizes that the context matters, but in common usage, the distinction is often overlooked. Comparisons are made to similar phrases, like "order of magnitude," to illustrate the point. Ultimately, the consensus leans towards interpreting the phrase as A being three times larger than B.

This is pretty urgent, I am really confused by this kind of wording.

Normally when people say A is a factor of 3 above B, do they mean A = B*3, or A = B*4?

Without seeing your particular context, I would normally take that to be approximately 3 times more than what it is compared to. As in 25 is about a factor of 3 times greater than 8.

Well in this context, there can be no approximate answer. So my question is really whether A is 3 times as large B or 4 times as large as B. This is more of an English question than math question.

My best guess then would be that it was 3 times and not 4.

It's comparable to saying something is an order of magnitude above. That is 70 is an order of magnitude greater than 7. It seems to me that someone would likely never mean that 77 was an order of magnitude above 7 and not 70.

I think most people in common usage don't make the distinction.
 
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...
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...
