AI Thread Summary
Centrifugal and Coriolis forces are classified as pseudoforces because they arise from non-inertial reference frames, where the observer is in an accelerating frame of reference. These forces do not originate from physical interactions but instead result from the inertia of objects within those frames. The distinction is that real forces, like gravity, act directly on objects, while pseudoforces are perceived due to the observer's motion. Understanding this concept is crucial for solving problems in physics involving rotating or accelerating systems. Thus, recognizing the nature of these forces helps clarify their role in dynamics.
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...
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.
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...
