I have Eg = Ep + El and the same thing for p
also E = square root of [(pc)^2 + (mc^2)^2]
and pc of photon will be equal -pc of elicon.
Substitute both of the above into the conservation of energy equation. I only have one unknow which is p of photon. But then I got a quandratic...
I've been trying to use energy and momentum conservation in this problem but it didn't work out or I got a quadratic equation and got 3 different answers. Can anyone help me please. Here is the problem

I've been struggling with this problem for hours. I don't know what I did was wrong. Someone please give me a hint or point out where I did was wrong. Thanks a lot.
There are three charges : the first charge of +2Q locates at (0,0), the second charge of -Q locates at (0,d), the third charge...
The problem doesn't give me the focal point. If the source is inside the focal point, the image can be on the same side of the source in the case of the converging lens too. So how can I tell? Thanks!
I got a problem where it gives us a diagram with a lens, a source and a image. We have to draw the three principal rays. But after drawing the rays, how can I tell if it is a diverging or converging len? And how can I explain it verbally? Thanks a lot!
I don't understand this problem. What is the different between filled rapidly and filled slowly? I think in c, when it's filled slowly, the temperature would stay the same at T= 280 K but what's about a and b. How can I do those? Any hint, please. Oh, and here is the problem

These might be really silly problems for a lot of you but I'll have an exam in 2 hours and I still don't know how to do these problem ( which's supposedly the types of questions that will show up in the exam). I'll be really appreciate if someone can help me!
