Here is the problem which I am confused on, please help me!
Problem: You have punched a hole in a tennis ball and run a string straight through it. You then hang the string from the ceiling so the ball hangs straight. You pull the ball back and release it so it swings.
1- Just after you have released the ball, what would the free body diagram look like?
I want you to clarify the physics in this above problem.
We move a square loop of wire 2.1 cm on a side into a region of uniform magnetic field of 1.0 T with the plane of the loop, find the force on the loop as it just enters the magnetic field region
A standing wave on a string is produced when one end is fixed and the other is driven by a 76 Hz oscillator. what is the total length of the string in meters
A diffraction pattern forms when light passes during a single slit. The wavelength of the light is 686 nm. Decide the angle that locates the first dark fringe when the width of the slit is (a) 1.7 x 10-4 m and (b) 1.7 x 10-6 m.
In a Compton scattering experiment, an x-ray photon scatters through an angle of 17.0° from a free electron that is initially at rest. Calculate the angle through which the electron scatters
