Electromagnetic Theory - Relativity

Two cultures of a certain bacteria each consist initially of just one bacterium. This strain of bacteria is known to double in number of every 24 hours. One culture is left on earth and the other is placed on a rocket that travels at 13/15 c relative to Earth. At a time when the culture on earth has grown to 256 bacteria, how many bacteria are in the culture on the rocket according to observers on Earth?

Coloumbs Law as applied to three charges

In this simulation, the red green and blue charges are originally at the vertices of an isosceles triangle. The green and blue are fixed in space and the red charge is allowed to move. Find the Net Coulomb force (magnitude and direction) on the red object due to the green and blue charged objects after 1.00s has elapsed. See attached file for full problem description.

Consider a bike moving with a speed of 0.80 past a stationary person. If the rider fires an object in the direction in which he is moving with a speed of 0.70 relative to himself, determine the speed of the ball relative to the stationary person.

A conductor consists of a circular loop of radius R and two straight, long sections. The wire lies in the plane of paper and carries a current I. Find an expression for the magnetic field at the center of the loop.
