1. You are driving south on the 405. You are in traffic so your speed is 35 miles per hour,
(35 mi/hr). Calculate your speed in m/sec. Assume that there 1.609 meters in every mile.

2. The Moon takes 27.25 days to make one revolution around the Earth. Calculate how
many seconds it takes for the Moon to make one revolution around the Earth.

Athin nonconducting rod with a uniform distribution of positive charge q is bent into a circle of radius r. the central perpendicular axis through the ring is a z-axis, with the origin at the center of the ring. a) what is the magnitude of the electric field due to the rod at z = 0? n/c (b) what is the magnitude of the electric field due to the rod at z = infinity? n/c (c) in terms of r, at what positive value of z is that magnitude maximum? r (d) if r = 4.00 cm and q = 9.00 µc, what is the maximum magnitude? n/c
