Sorry, I forgot to mention, I'm hoping to go to university for Physical Sciences.

Hey, I enjoy to do physics, math and work with computers, but all the jobs I know of that consist of these subjects do not interest me. Maybe there's something I'm missing or something? A job like theoretical physics would interest me, but how does someone make a living doing something like...

Sorry, for the second equation, there is 1.0g magnesium oxide and 100.0 mL of 1.00 mol/L HCl.

Okay so I think I know what I'm doing, but I have a lab tommorow and I have to use Hess's Law to find the total enthalpy change of Mg(s)+1/2O2(g)-->MgO(s). I know how to do that but during my lab tommorow I have to find the enthalpy change of 2 reactions. First, Mg(S)+2HCL(aq)-->H2(g)+MgCl2(aq)...

I have but it's very vague, like if I get a masters in physics, will I be able to get a good job, or would that be a waste of my time?

Hey, I was wondering what you can do with a university degree in physics or mathematics. I know one thing you can do with a physics degree is get a masters degree in astronomy, what are other things you can do, as well as things you can do with a mathematics degree? I really enjoy maths and...

Ohh okay I got it. Because the force of the magnetic field equals the net force (F=ma) so that means that qvb=ma and then since v=rw and a=vw it's qrwB=mvw, and then the w's cancel out and you rearrange. Thanks a lot :biggrin:

F=qvBsin(theta) is the equation right? and, I probably have seen the first one, but can't remember that specific one.

Where did the formula r=mv/Bq come from in my answerbook for my grade 12 physics? Thanks.

Hey, I have a test tommorow and I don't really understand gravitational potential energy or kepler's laws. It's not really a theory test, it's the math aspect, but I still don't understand it. I know of the formulas such as Fg=Gm1m2/r^2, Eg=Gm1m2/r, Ek=1/2 mv^2, and I think that's all. But...

Hey, I can't decide on what I should go to university for after high school. I enjoy maths and sciences, but I also enjoy the human body (eg. kinesiology). I guess what I'm asking is what kind of jobs could I get in maths or sciences, and possibly what degree that would be if possible. Also, I'm...

Oh alright, I understand it now, thank you. I didn't think of it that way :biggrin:

Hey, I have a question I'm stuck on for my grade 12 physics class. There is a block being pulled by tension over a triangle essentially that's at a degree of 35.7 (right angle triangle). I understand the whole question but I don't understand how to find how much pull the block has backwards of...

Does anyone have a good website for some questions/answers for Newton's three laws (I'm not sure if he made more, but the inertia, the net force must be zero when something is not moving, or moving at a constand rate, and the for every action there's a reaction). I've got a test tommorow, and I...
