The discrete random variable K has the following PMF:
p(k) = { 1/6 if k=0
2/6 if k=1
3/6 if k=2
0 otherwise
}
Let Y = 1/(1+K), find the PMF of Y
My attempt:
So, I am really confused about what this is asking.
I took...
Okay, I figured it out:
10.2=1/2(mh)V^2
20.4=(mh)V^2
mh is equivalent to the mass of a proton which is 938E6 MeV/C^2
so, 20.4/938E6=v^2
so V^2 = 2.17484E-8
v= 1.474E-4
You have to multiply by c, I am not exactly sure the reasoning but
1.474E-4 * 299792458 = 44211.4107m/s...
Homework Statement
Two hydrogen atoms, both initially in the
ground state, undergo a head-on collision.
If both atoms are to be excited to the n = 2
level in this collision, what is the minimum
speed each atom can have before the collision?
Answer in units of m/s
1 mol of hydrogen is...
