A "sandwich" is constructed of two flat pieces of metal (0.70 cm on a side) with a 1.0-mm-thick piece of a dielectric called rutile (K 100) in
between them. What is the capacitance? (E0 = 8.85 x 10-12C/N m)
43 pF
4.3 nF
8.85 uF
6.2 pF
0.62 nF

Suppose while hauling rocks, you accidentally drop one. it breaks apart in flat, planar sections. what type of rock did you just drop? 20 points

What’s #16 asking and how do i solve it?

Two point charges are separated by a certain distance. how does the strength of the electric field produced by the first charge, at the position of the second charge, change if the second charge is doubled? a. the field does not change b. the field strength decreases by half. c. the field strength doubles d. the field strength quadruples
