I am new to the fluence concept which is apparently the number of particle passing through an area. However how can this quantity ever be greater than zero...? In my mind there needs to be a timing interval to compute how many particles are passing through the area which I know is referred...

That makes sense but I don't see how the total energy as stated in the solution is the square root of kinetic energy squared plus two times the kinetic times potential...?? Forgive me, I've been doing too much physics today and perhaps it's obvious but I'm not getting this one.

I see that yields p= sqrt(2mT) but the solution is saying that p= sqrt(T^2+2Tmc^2) where is this coming from??

I am trying to follow this solution but I can't see how the momentum p is equivalent to the sqrt(T^2+2Tmc^2) I get that T=p^2/2m which yields p=sqrt(2mT) but why is there a T^2 term...??

How would one find the velocity of this electron. Is it considered relativistic or will 1/2mv^2 work just fine??

It doesn't say. I guess that I will assume such. Is the 'E' in the equation I am using for the rest mass energy plus the kinetic energy?

How would one calculate the velocity of a 1MeV neutron?? I tried the following the attached formula for V/C but E is less than the rest mass which yields the square root of a negative number. Not sure what to do for this

Unfortunately that is all that is given with no other information. My mind is blown as to how to solve this. My initial approach was to create a table / convert this form to the standard ax+by+cz=d. I am under the impression that y(x) does mean y is a function of x and similarly with x(z)...

Got it! Sorry i didn't have my reading glasses with me but now i can see now that I've been using delta instead of gamma. Thanks for your help!

Yes, it took me min but now I see it! Very sneaky. I don't see how this becomes t=δ(t'+vx'/c^2)... Apparently δ(vx'/c^2) = [x'/δ(v)](δ^2-1) but there must be some other trick to reduce to the standard formula

Homework Statement Prove or disprove the linearity of the following function y(x)=(z^2)x(z) Homework Equations I know how to determine linearity of functions in a 2-d plane but not in 3 dimensions. The Attempt at a Solution How can one attempt to plot this function by making a...

I agree but the assumption is that I do not know the equation for t or t', only x and x'. I see this approach on numerous websites including the wikipedia derivation but everyone seems to get to where I am the just write that this becomes the familiar t=(gamma)(t'+vx'/c^2)

Hi all, I'm trying to derive that t=δ(t'+vx'/c^2) Using x'=δ(x-vt) then substituting for x=δ(x'+vt') I should be able to isolate t and solve the problem but I am getting to the following point after simplification and can't figure out where to go next...? x'= δ[δ(x'+vt')-vt] (isolate...
