What happens to the velocity of light when it passes from a vacuum into air? My friend and I aren't sure what happens and we have a test on this. We both think it slows down.

I know that these are relatively easy questions, but I'm having some difficulty with them.

How much work does the electric field do in moving a proton from a point with a potential of +1.30E2 V to a point where it is -25 V? Express your answer both in joules and electron volts.


How much kinetic energy will an electron gain (in joules and eV) if it accelerates through a potential difference of 2.2E4 V in a TV picture tube?


for the first one i've tried using the equation PEb-PEa=-Wba, and i'm not getting the right answer.

the second one im not really sure how to work it.

Any help will be greatly appreciated!

We are looking at a 20' tall tower with three parallel sides. (perpendicular to the ground) The angled front face is @ 81 degrees. The upper portion of our tower is 5' x 3’ with its base measuring 2' x 3'. The center of gravity is out side of this base and it will tip over. How do I determine the amount of force required to prevent this. (Currently, two steel feet, connected to the towers base, are meant to prevent its tipping. I believe that due to the weight of each of the eight panels [50lbs each] and the degree to which the front face is angled, that the feet will not be sufficient to prevent its tipping unless additional weight is added to each footing) Please Advise

I would like to know if the high energy radiation from a Linear Accelerator (18 MV) can cause the appareance of white points in the image showed by a PTZ color camera (w/auto focus, zoom, etc.)?.

By the way, I already have installed two CCD small cameras B/W, and work just fine after some shots with 18MV.

Two blocks with masses m1 = 1.10 kg and m2 = 3.40 kg are connected by a massless string, as shown in the Figure. They are released from rest. The coefficent of kinetic friction between the upper block and the surface is 0.250.

Assume that the pulley has a negligible mass and is frictionless, and calculate the speed of the blocks after they have moved a distance 52.0 cm.
