1. A diverging lens with a focal length of -14 cm is placed 12 cm to the right of a converging lens with a focal length of 18 cm. An object is placed 33cm to the left of the converging lens. Where will the final image be located. 2. 1/f = 1/di + 1/do dob = L - dia 3. After solve...

Homework Statement http://i124.photobucket.com/albums/p27/lollipopgourmet/untitled.jpg If the couple has a magnitude of M, determine the magnitude F of the couple forces. Since this is an X-Y plane, I assumed the equation would simple just be M=Fd, where I know the moment, and just have...

Yeah, the orientation of the plates is negative on bottom and positive on top.

At what angle will the electrons leave the uniform electric field at the end of the parallel plates? Assume the plates are 4.9 cm long and E = 5.0 x 10^3 N/C. *The answer to this question is -23 degrees. So far what I have tried to do is find the position of the electron on the y-axis and...

I didn't view calculus II all that challenging besides it just introducing new ways to use the information you learned in calculus I and previous courses. I think it's calculus III which is when things start to be challenging, mostly just because of the amount of material that is required to be...

Nevermind, I got it, it's 28*2pi

Homework Statement Find the work done by the force field F(x, y, z) = 3xi +3yj + 7k on a particle that moves along the helix r(t) = 4 cos(t)i + 4 sin(t)j + 4tk, 0 ≤ t ≤ 2π (As in the previous problem, recall that the work of the force F on the helix corresponds to the circulation of this...

I read your whole post. Engineering is not a hard subject for me, just a challenging one. A physics major would be just as challenging. It's not a matter of difficulty that is swaying my opinion, it's a matter of understanding. As much as I'd enjoy applying the classical physics I am learning in...

Homework Statement Consider the curve r = (e^−2 t cos(3 t), e^−2 t sin(3 t), e^−2 t) . Compute the arclength function s(t) : (with initial point t=0 ). The Attempt at a Solution r'(t) = <-2e^-2t*cos(3t) + e^-2t*-3sin(3t), -2e^-2t*sin(3t) + e^-2t*cos(3t), -2e^-2t> Then what...

Homework Statement r(t) = 〈sin(t) − t cos(t), cos(t) +t sin(t), 5 t2 + 7 〉 Find the unit tangent. T(t)= The Attempt at a Solution r'(t) = <cos(t) + tsin(t), -sin(t) + tcos(t), 10t> T(t) = r'(t)/ |r'(t)| |r(t)| = sqrt( 1 + 101t^2) And so on. Supposably according to the...

...but it's not just like one or two courses I'd have to take to get a degree in physics. It's about 10.

As of right now both majors have covered a lot of the same material, not including the organic chemistry and some other specific chemical engineering courses. With chemical engineering at UA, it's not uncommon for a semester to be 18 credits full with necessary classes. Taking a double major...

I tried this before with no avail, so this time I'm going to be a little more expressive about my situation. Currently my major is chemical engineering, it's a fun major in its own right, and has many possibilities when you obtain a degree. I attend the University of Akron, it's a rather highly...

They're only well known and respected schools. It doesn't mean you aren't any less smarter if you didn't attend MIT.

The University of Akron. It's a small school, it's worth checking out. It's currently the school I'm attending for Chem.E. and they're proficient and are ranked as high as well as higher than some schools such as MIT, polymers being one of such the cases of where they are ranked either 1st or 2nd.
