Homework Statement
A beaker has a height of 40.0 cm. The lower half of the beaker is filled with water (n = 1.333), and the upper half is filled with oil (n = 1.48). To a person looking down into the beaker from above, what is the apparent depth of the bottom?

Two coils have the same number of circular turns and carry the same current. Each rotates in a magnetic field in a setup similar to the square coil in the figure below. Coil 1 has a radius of 4.2 cm and rotates in a 0.19 T field. Coil 2 rotates in a 0.42 T field. Each coil...
I figured that using the 0.8 twice is part of my problem, but I'm honestly lost as to how to determine Vb and Va, etc. without any information about a charge at each of those points, let alone calculating delta(v) between those without any of that information. If someone could give me a clue on...

a) Determine the electric potential difference VB - VA between the points A and B.
The answer here is...
Okay, I was able to answer part a of the problem (143.84 N/C), but I'm having some trouble with the second part of the problem and hoping that someone can assist me. I believe the angle that I need to use to calculate the x and y components is 26.6 degrees. There also is not an x component to...
