I'm about to finish my high school and since I'm really interested in stuffs like mathematics, physics and computing I want get into electronics or computer engineering. I live in a third world country and I really want to go to U.S to have a engineering degree so if I go there I'll have to...

Project: Weighing machine based on potentiometer Principle: On changing the length of the wire current in the circuit will change which will change the deflection in the ammeter Set up: On top of four or three spring(same spring constant) a board is attached so when a weight is kept on top...

So you're saying if two opposite waves of different amplitudes and frequency superimpose, velocity of the resulting wave will not be zero therefore standing wave is not formed?? Correct me if I'm wrong

I came across a question about wave from univeristy physics (sears n zemansky) and the question was 'can a standing wave.be produced on a string by by superposing two waves traveling in opposite direction with same frequency but different amplitudes? And same amplitude but different...

Homework Statement one gram of ice at 0 degree C contracts in volume by 0.091cc on melting. 9gm of a metalis heated to 200 degree C and dropped into and ice calorimeter. The decrease in volume was found to be 0.0182 cc. Calculate the Sp. heat of the metal (ANS:0.09cal/gmC) Homework...

if tangential acceleration is considered to be zero in uniform circular motion then why is uniform circular motion is called accelerated motion??

How is tangential acceleration zero in uniform circular motion?? Homework Statement the magnitude of tangential velocity is same but the directions are different..so how can the tangential acceleration be zero?? Homework Equations The Attempt at a Solution
