Q. The initial speed of school bus is 10m/s. If the bus slows down to 2.00 m/s in 1 second what is the acceleration (positive or negative) of the bus?

Q. Assume we have an infinitely long wire carrying a current of 2-A. It is bent into an L-shape extending into positive infinities along the x- and y- axes. Find out the magnitude of the magnetic field at a point P with coordinates (0.3 m, 0.3 m).
