The xy plane is "painted" with a uniform surface charge density which is equal to 40 nC/m2 . Consider a spherical surface with a 4.0-cm radius that has a point in the xy plane as its center. What is the electric flux through that part of the spherical surface for which z > 0?
a. 14 N / m2/C
b. 11 N / m2/C
c. 17 N / m2/C
d. 20 N / m2/C
e. 23 N / m2/C

A tracking station on Earth observes a rocket move away at 0.370c. This rocket is designed to launch a projectile at 0.505c relative to the rocket
What speed (in terms of the speed of light) does the tracking station measure for the projectile if it is fired (a) straight ahead of the rocket or (b) backward from the rocket?
Given that the total number of atoms on our planet remains fairly constant, how is it ever possible to deplete a natural resource such as a metal?
A) The problem remains that not everyone recycles as they should. B) Recycling only forestalls the inevitable depletion of metal resources. C) The atoms don't leave our planet, which is why naturally occurring materials never really reach the point of depletion. D) The problem is with the expense of collecting metal atoms that are uniformly dispersed.
