Homework Statement
1-3 A burst of 1014 electrons accelerated to an energy of 15MeV per electron is stopped in a copper target block of mass 100g. If the block is thermally insulated, what is its temperature rise? The specific heat of copper is 0.09 cal/g K
Homework Equations
m*Cp*dT = dQ
The Attempt at a Solution
Assume 100% of KE transfer to heat.
Negligible mass increase.
(100g)*(.09 cal/g K) dT = 1014 electrons * 15 MeV/electron * 2.6144*10^(-13) cal/MeV
The solution is supposed to be 6.3 K but what I have above isn't even remotely close (way too small). I'm trying to guide myself through a special relativity book and given this is was the only problem in the beginning I couldn't get to matchup I feel a bit awkward posting it because it seems so simple : /.
