Usually, when you are transferring to be classified as a transfer student, you need a certain number of hours completed at the undergraduate level.
Check with the college to see whether you will be classified as a transfer or incoming student.
If I move a strip of copper mechanically with my hand through a uniform magnetic field will their be a drift velocity? And if so will the drift velocity be in the same direction as the moving copper strip? What would the magnitude of the drift velocity be if this happens? Can you have a drift...
Do you know of anyplace that offers credible proof like in a book or an article?
This was a test question and I argued with my physics teacher about it. He thinks the electric field will decrease.. where I do not and he said I am wrong.
I would like to show him that the electric field...
I have a question that is confusing me perhaps one of you can help me.
If I hook up a constant potential difference to a capacitor and place a dielectric inside of it, will the electric field decrease even if the plate separation remains constant?
I think that the capacitance will increase as...
Hello guys I am not sure if I am doing this right. If you could offer any advice or point out my mistakes I would appreciate it.
Problem: Sketch the graph of the domain of f(x,y,z) = \frac{1}{x^2+y^2-z}
Domain: (x,y,z) \in R^3 \mid x^2+y^2 does not equal z
Graph: I set f(x,y,z) = 1 and...
I am looking for the domain, range, and graph of this level curvef(x,y)=\sqrt{x^2-1}
I have the range, but the domain and graph I am unsure of.
For the graph, I graphed on my paper x=1, you plug in one, z = 0 and x = 1 and y can be anything.
Domain: I am unsure of but yes \mid x \mid \leq 1...
I am trying to find and graph the level curve f(x,y)=\sqrt{x^2-1} that passes throught the point (0,1), as well as its domain and range.
I am not sure if my reasoning is right, so let me know if I got the wrong idea.
For the graph I have x = 1 which is independent of y and is just a...
Infinite Series Calculus 2 hw problem
Hello. I need help finding the answer on two of these.
#1. Find a power series representation for f(x)=ln(1+x^2)
I have
f'(x)=\frac{(2x)}{(1+x^2)}
So I factor out 2x and have \frac{1}{(1+x^2)} which is a geometric series =
\sum(-1)^{n}x^{2n} then...
Any specific height you are looking at? We don't go flying towards the star because the gravitational effects from a star light years away is negligible compared to earth's.
Yes, the change in x is 30m.
Tenali, he is looking for the coefficient of kinetic friction.
You can find the coefficient of kinetic friction using the kinematic equations as Tenali suggested, but that isn't the way the problem is meant to be worked, but it will work.
Don't worry about accelerations. You can if you want but it will make the problem more confusing to you I imagine. It is just an energy problem.
The thing to remember is that the f = (W \times {\Delta x}) = {\Delta KE}
Also, remember f=\mu{mg}.
The work done by friction must be equal in magnitude to the kinetic energy of the sled-person system but opposite in sign for the object to be at rest after displacing 30m.
Knowing work is equal to Force \times Displacement you can then solve for friction which then allows you to obtain the...
Hey guys, I am curious if I am setting this up right. Could you take a look and make sure I am on the right path?
I have three questions.
1) I am trying to find the area bound by y=x^2 and y=4x+5
Upper function y=4x+5
Lower function y=x^2
For my integral I have \int^{5}_{-1}4x-5-x^2...
I can't figure out what I did wrong on this test question.
A 4kg block is dropped from a height of 0.8m above a spring, k=120N/m. Find the maximum compression of the spring.
I have the PE at the top is equal to KE at the bottom.
PEtop=31.4J
KEbottom=31.4J
The potential energy in the...
