How can i figure out the instantaneous position of an object using an acceleration time graph. Iam also given initial velocity and initial position? Thanks
Calculating Position from Acc. Time Graph
AI Thread Summary
To determine the instantaneous position of an object using an acceleration-time graph, calculate the area under the curve to find the change in velocity over specific time intervals. This change in velocity can then be integrated to find the corresponding change in displacement using a velocity-time graph. The initial position and velocity must be factored in to arrive at the final position. While there isn't a single formula for this process, the relationship between acceleration, velocity, and displacement is crucial. Understanding these concepts allows for accurate position calculations from an acceleration-time graph.
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...
