Hello again PF, I now need to decide whether to pursue an engineering physics or pure physics degree for my undergrad, I've been accepted to both, but am unsure what would be the better fit for me. I obviously like the extra job security that an engineering degree would carry with it, but I'm...

Homework Statement Calculate the [OH-] concentration in a 0.5 M solution of potassium fluoride (KF). Ka for HF is 7.2 × 10−4.The Attempt at a Solution I know that KF → K+ + F-, therefore having a 1:1 ratio, [F-] = 0.5M ,but from here I am unsure what to do with the F- concentration. I know that...

I can balance this equation using the half reaction method, but I want to learn to use the oxidation number method with this particular question to "broaden my abilities". Homework Statement ICl → Cl- + IO3 + I2 The Attempt at a Solution I: +1 → +6: lost 5e- I: +1 → 0: gained 1e- (I'm...

Homework Statement A toy rifle shoots a spring of mass 0.008kg and with a spring constant of 350 N/m. You wish to hit a target horizontally a distance of 15m away by pointing the rifle 45o above the horizontal. How far should you extend the spring in order to reach the target? Homework...

In that point in life where I have to make the hard decisions for my future and was just wondering what kind of university path you have to take to get into medical physics. Do you need an MD, PHD? Should your undergrad be in engineering? When do you specifically specialize into medical...

Never mind, I foiled it out and managed to figure it all out. It didn't help that I was mistakenly looking at the term of a series formula for arithmetic series rather than the sum formula :-)

So I was just working through Courant's calculus and am a bit confused as to where a few variables are pulled out of. Homework Statement Integration of f(x) = x We can see that a trapezoid is formed, so the relevant equation: 1/2(b-a)(b+a) is the value of this integral. To confirm that our...

So would I just have had to specify xx.xx N [0deg. E] to be correct? Or are you implying that there is some arbitrary angle in which that force can be broken into a y-component, if so I don't have the first idea on how to find that angle.

Some background: This was a quiz I recently had in which I lost a few points for missing an "x & y component" for one of the directions. My thinking is that because the problem was not actually set up with a specified order of charges there are a few different answers you could get. I intend...
