Unfortunately I took 4+ years of university calculus over two decades ago. I've gone well beyond this but obviously haven't used these skills in a very long time, which is why I'm having trouble getting started. I'm not looking for anyone to do my homework for me, I just can't remember very much...
That doesn't seem right- how would that help? Seems like substitution would work here...
This seems closer...
\int(x^2+z^2)^\frac{-3}{2}}dx
\frac{(z^2+x^2)^\frac{-1}{2}}{\frac{-1}{2}}
I kind of see the
\frac{x}{z^2}
term, but why no
\frac{x^3}{3}
Here's an easy one, I know the answer but can't get there...

The Attempt at a Solution
I know this approach is wrong, but why? Or am I not finishing somehow?
\int\frac{1}{x^3}dx+\int\frac{1}{z^3}dx...
I'm having trouble understanding conservation of 4-momentum. My problem is about dertermining the threshold for triplet production from a photon and an electron using 4-momentum conservation. The answer is 4m0c^2. So far, I say the initial energy is:
E1^2=(pc)^2 + (m0c^2)^2=(hv)^2+(m0c^2)^2...
I'm a bit confused about the way radiation is said to 'transfer' its energy to matter. I must be looking at it the wrong way, so I'd appreciate it if someone could explain what I am missing. I don't see how energy is transferred to atoms through ionization.
The way I see it is charged...
Ok, I figured it out. I need to take the binding energy and subtract it from the total mass of the separate nucleons to calculate the true mass to find Q. Hooray!
I think I am doing this correctly, but getting a strange result. Here's the original problem dealing with decay modes:
The isobars 37Ar and 37Cl have binding energies/nucleon of 8.279 Mev and 8.336 Mev, respectively. Show which nuclide decay to the other spontaneously and by what decay mode...
This is a small part of a homework problem in which I need to calculate neutron flux. I have the neutron beam hitting a copper target, and two reactions take place Co-59(n,p)Co60metastable (cross section=19barn) and Co-59(n,p)Co60ground (cs=18barn). What is the cross section overall? Do I simply...
Hello. I'm a little unsure of how to proceed on this problem... Here it is:
A 3-Gev proton flux is monitored by measuring 24Na activity induced in 25 microm (6.85 microg/cm2) aluminum foil via 27Al(p, 3pn)24Na reaction (for 3 Gev protons, cross section = 9.1 mb). Exactly 15 hr after the end...
Always the easy things we forget...
I know how errors propogate through multiplication or division when every term has an error, but how do I propagate errors in equations when only one term has an uncertainty? I want to say just multiply and divide the uncertainty value by the constants, i.e...
