Derivation of velocity in nth Bohr orbit • Physics Forums Homework Statement (a) Derive an expression for the electron's speed in the nth Bohr model (b) Prove that the orbit with highest speed is the n = 1 orbit,with v(1) = ke^2 h compare this with the speed of light , and comment on the validity of ignoring relativity (as we did) in
Solving for distance using only initial velocity and coefficient of . . . Actually, althought relating the Kinetic Energy equation to the equation about friction and distance might be conceptually valid, it isn't the clue this person needed 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 student is expected to provide the resulting
Problem in understanding instantaneous velocity - Physics Forums The average velocity is the rate of change of position over a time interval, while the instantaneous velocity is the rate of change of position at a point in time As a time interval approaches a point in time, the average velocity approaches the instantaneous velocity
Velocity of air coming out of a nozzle - Physics Forums If the pressure on one side of the orifice is constant and less than the critical choke pressure, then that should be the velocity If the pressure is coming from an air tank of finite volume, this velocity is just a snapshot in time The pressure, and therefore velocity, will decrease over time
How to Determine Velocity from a Force-Time Graph? Position from velocity time graph Sep 1, 2018 Replies 4 Views 4K Calculating velocity from the position versus time graph May 20, 2020 Replies 20 Views 3K Distance-time graph of a ball throw vertically up from a fixed point
Relation Between Spring Constant and Angular Velocity I was going through Periodic Motion chapter of my book and came across an equation while defining the relation between Time Period of on oscillating particle and force constant k m=w2 which was applied in, T = 2xpie angular velocity can anyone please help me define this equation I can't seem
Calculating Nozzle Flow Rate - Physics Forums Calculating Nozzle Flow Rate To work out the flow rate of water from a nozzle we need to work out the volume in a given period of time To do this we work out the area of the nozzle and then multiply it by the velocity of the water coming from the nozzle to give us volume per unit of time
Find Velocity given Force and Mass - Physics Forums Velocity is the speed at which an object is moving It can also be thought of as the speed of a moving object divided by the time of travel In this case, it is the speed of a body divided by the time taken for the body to move a given distance
