Thank you so much for clarifying. The course I'm doing is the American School of Correspondence's Conceptual Physics course, which is meant for homeschooled students (as I am).
They develop the exams and "study guide" themselves, and they obviously have no influence on the course book --...
Q = CV
Where Q is charge; C is capacitance and V is voltage.
So I think I know what you're saying... I had capacitance and voltage a bit backwards here.
So as the radius increases, capacitance, not voltage, increases and the voltage decreases. And by that formula given earlier, (voltage x...
Hmm maybe I should mention that the course I'm doing is a conceptual Physics one and we don't learn JACK about the mathematical side of things. "Q = CV" is nowhere in my textbook so I guess I've got some googling to do... Thanks for your input :D
"The figure below is a lines of force representation of an electric field."
"In the figure above is the electric field stronger at point X or point Y What evidence in the diagram indicates that this is the case?"
My answer: Y. Because the lines of force are closer together.
In what direction...
Hello~ I've got a confusing question;
"If a Van de Graaff generator is charged to 50,000 volts, how much energy does it take to add an additional electron to the charge on the sphere?"
(The charge of an electron is given as -1.6 x 10^{-19}C)
My answer: (50,000 V)( -1.6 x 10^{-19}C) = 8.0 x...
Wow, thank you for the picture and the clear explanation! It's a bit late here but let's see if I can articulate this into something coherent. The answer for be would be:
"Is it correct to say that the difference in patterns produced by the monochromatic and white light is caused by the fact...
Hello again Simon! Thanks for your response.
Frankly, I don't think I need to be more specific as the words "maximum" are at no point mentioned in my textbook. The section on diffraction grating is about half a page long. What I'm trying to say is this course is not that in depth. (I wish...
(A) What kind of pattern of would you get if you shone monochromatic light on a diffraction grating? What pattern of light would you get if you shone white light on a diffraction grating?
My answer: With monochromatic light, you would get a pattern of alternating light and dark bands. With...
Hello again! Just a few multiple choice questions.
When blue light strikes an opaque object whose resonant frequency is the same as the frequency of the blue light what happens? ( Choose as many as apply)
A) The amplitude of the vibrations of the electrons in the object becomes larger
B) The...
Oh my. Well, it's almost midnight here and I've answered every question on my exam except this one. So here's what I'm going to write;
E) How fast would you have to be going and in what direction to experience weightlessness?
Solution Attempt: You would need to move to the center (or...
Wow! Thanks for helping me again :D
Oh duh
Centripetal Force = \frac{Mass X speed^{2}}{radius of curvature}
So it will increase as you go faster.
For the last question, I understand that at the halfway point of the outer edge and the center of the habitat, gravity would be 0.5...
Maybe I need to take a little break from my studies but I'm not getting this at all. At the risk of looking really dumb, here's what I need help with;
Imagine that you are living in a rotating space habitat. The habitat has a diameter and a rotational speed such that at the outer edge you...
Thank you for taking the time to comment. Now that I've mulled it over a bit, it's obvious it's B. I didn't really understand what momentum was (mass x velocity). So an object with a net force acting on it of 0 could be moving at constant velocity or at rest, have no acceleration and a...
Hello again! This time I have a bunch of multiple choice questions, some of which I'm really not sure on, so I'd really appreciate a little help. Questions I'm really unsure about will be marked in red.
In these questions we are to assume g = 10 m/s^{2} unless otherwise specified.
