May 17, 2025 · There are 3 particles a, b and c. A moves towards B with velocity 5 m/s and B moves towards A with same speed as A. C moves such that separation between B and C is …

for measuring velocity of water so we have to calculate velocity using head calculation or from stagnation pressure which we measure using a pitot tube. Calculate Velocity from Head We …

Oct 26, 2008 · 1. How do you find the velocity of an object if you are given the x and y components of the velocity? 2. Not sure! 3. It makes the most sense to use the Pythagorean …

Aug 1, 2009 · The problem here is that you have a fundamental misunderstanding of what acceleration means in relation to velocity. Consider a curve of velocity vs. time. At some time, …

May 28, 2025 · The first is the velocity of wave propagation along the boundary between the material and air or space. That will be close to the speed of light, slowed down by the dielectric …

Jun 6, 2025 · In Dirac's "General Theory of Relativity", he shows how in the weak field, low-speed limit, Einstein's equation gives Newtonian gravity. Along the way, he takes derivatives of the …

Jul 18, 2016 · I know the flow rate of gas (products of combustion + air) entering a natural draught (no fans) flue. If the flue is removing all the gas: velocity of flue gas = flow rate (corrected for …

Apr 28, 2015 · For our purposes, in this project we are assuming the height in the tank is constant, as you said. This will ensure a constant pressure at the bottom of the tank, in theory …

Nov 24, 2008 · At the early point (probably around chapter 4) of an "elementary physics" textbook, a student encounters problems where, given an initial velocity and coefficient of friction, the …

Jun 3, 2025 · Because the system has no friction, when the point mass falls, I think both angular momentum and energy are conserved. Further because the rod is massless, there cannot be …
