Thank you

Anyone else want to chime in, I still don't know which is correct.

That gives 0.5625, can you explain WHY you would use 30 degree for the second polarizer when the axis is 60 after the coming out of the first one?

Thank you Okay so Velocity changes direction in circular motion. Let me go through my thinking. (A) Mag fields CAN change direction, look at the mass spectrometer for example. (B) We established is incorrect C) The one in question. D) Should be false based on the the right hand rule...

So I know the equation: Itrans = I0 Cos2θ Since this light starts out as polarized, there is no need to cut it in half like you do for unpolarized light. So I did the equation through the first polzarizer, using 30 degree as my angle, and came out with I=0.75 Now I used that 0.75 as my new...

So you have to reply? PLEASE HELP, I have a test in an hour and to me all these answers seem false.

Constant speed means there is no acceleration, thus C) is false. Am I correct that B is also wrong?

I known that a varying magnetic field causes a an electric field that can do work, is that what you mean?

What statement about magnetic fields interacting with a moving charge is correct? A) Magnetic fields can’t change the direction of motion of a moving charge. B) Magnetic fields can do work on a moving charge. C) Magnetic fields can accelerate a moving charge. D) The force on a moving charge in a...

Not to sound ungrateful, but can you please just tell me the answer?
