eatubbs, Stick with problem 2 first. The question asked is: How much HEAT is needed .. In other words we want to know Q=ENERGY=in Joules. This is not temperature. When you apply heat/energy, there is a change in temperature. ie from 20->40C. using Q = mass x sp.heat water x change in...

eatubbs, In problem no 2, you are missing the specific heat of water. To find Q, the heat needed in Joules, I would set it up this way: Q = mass x sp.heat water x change in temp.

DeadWolfe, HallsofIvy makes a good point. I'm a first year Phys major, and what I do to combat looking back at endless white paper is: 1. Use yellow paper - 16-20 pound/recycled 2. Use black, red and blue pens for highling and circling. 3. Do BPN- Bullet Point Notes. Every time you hear a key...

Damped functions Nearly all real world oscillating systems have some dissipatives forces. Therefore, their oscillations die out over time-unless we provide some means for replacing the dissipating mechanism. The decrease in amplitude caused by these frictional forces is called damping-and the...

Thanks Astronuc.

Please continue with your thread Mellow^Guy. My major was going to be plasma physics, but UC Berkeley calls it Nuke Engineering. How do engineers think as opposed to physicists? etc. I'm terrified. Please, post some more! Thanx.

I'm hedging my bets on saltwater. Hot fusion seems to be our only road forward. I'm still undecided as to whether I should study magnetic confinement or inertial/laser systems though. My gut says "magnetics", but laser-type systems have become more viable. Is this correct? This is my first year...
