You have a 2.5m long copper wire. You want to make an N-turn current loop that generates a 1.2mT magnetic field at the center when the current is 1.9A. You must use the entire wire.
Part A What will be the diameter of your coil?
The position of an air-track cart that is oscillating on a spring is given by the equation x = 12.4 cos[(6.35 s-1)t] . At what value of t after t= 0.00s in the cart first located at x = 8.47 cm ?
A converging lens (f = 14.6 cm) is located 31.4 cm to the left of a diverging lens (f = -7.91 cm), Find the overall magnification
Perpetual motion machines have fascinated people especially inventors for hundreds of years before the laws of thermodynamics became known. Ideally, once energy is added to start a perpetual motion in machine, the machine would continue to operate..
Using kinematic equations prove that if two balls are released simultaneously from a table, one with zero velocity and other with horizontal velocity, they will both reach ground at the same time.
