hi, please can anyone analyze the following sentence in terms of the formulas of electrostatic forces or Potential energy (assuming electrostatic force is directly proportional to potential energy)
statement: "When the force between two objects is attractive and decreases with distance, the...
the last part of the problem
the last part of the problem by taking the absolute pressure of the right side equal to the atmospheric pressure only by taking the gauge pressure there as 0 while in the left part we are asked to find the gauge pressure. how come one has no gauge and the other has
why is when working with Bernoulli equation the absolute pressure that we are NOT looking for has a gauge pressure = 0 and only atmospheric pressure while the one we are looking for has both? is this a rule somehow ?
hi i just want to ask about the formula of Doppler Effect . The speeds of the listener VL and the source Vs are relative to the ground, source, or listener ?
YESS EXACTLY after looking to the problems again i realized that one asked about the total force and the other asked about the force done by water. but the problem is i don't know the difference and that is why i didn't realize the difference. Can You please give me a summary about the...
Hi please check the highlighted question in the attachment and the solution and see the problem, i need help please. I have two questions about it:
1- why didn't we take the plug as a vertical wall and thus the force would be integral of pressure x area?
2-WHERE DID THE FORCE DUE TO...
I've been solving fluid mechanics problems and i encountered two problems that made no sense to me. Both problems that ask about the force done by water on a VERTICAL wall under the level of water. One problem was solved by taking the integral of the gauge pressure and multiplying it by the...
