The coil is rotated through an angle of 90° in 0.2 second. Calculate the magnitude of the average e.m.f. induced in the coil while it is being rotated.
Two wires, both carrying current out of the page have a current of magnitude 2.0 mA and 3.0 mA, respectively. The first wire is located at (0.0 cm 5.0 cm) while the other wire is located at (12.0 cm 0.0 cm). What is the magnitude of the magnetic force per unit length of the first wire on the second and the second wire on the first.

A 220 V – 5 A electric lamp is used for 30 minutes. How much energy does it require
Incident x-rays used in Compton scattering experiment have a wavelength of lambda= (4+43/10)pm . If the X-rays are Compton scattered through an angle of 160 degrees, what is the wavelength of the scattered photon?

A man of mass m1= 70.0 kg is skating at v1= 8.00 m/s behind his wife of mass m2= 50.0 kg, who is skating at v2=4.00 m/s. Instead of passing her, he inadvertently collides with her. He grabs her around the waist, and they maintain their balance. (a) Sketch the problem with before - and - after diagrams, representing the skaters as blocks. (b) Is the collision best described as elastic, inelastic, or perfectly inelastic? Why? (c) Write the general equation for conservation of momentum in terms of m1, v1, m2, v2, and final velocity vf . (d) Solve the momentum equation for vf
The coil is rotated through an angle of 90° in 2.0 second. Calculate the magnitude of the average e.m.f. induced in the coil while it is being rotated.
In a particle accelerator, two particles with masses such that m1 = 3m2 collide. Particle 1 is initially moving at 1.5 x 107 ms-1 and particle 2 is moving in the same direction at 0.5 x 107 ms-1
a. Calculate the final speed of each particle assuming the collision is elastic.
b. Calculate the final speed of each particle assuming the collision is perfectly inelastic.
