I just want to know if this is the correct approach or if there is another way. I'm not asking you to do it for me. I'd imagine you either know how to do this problem or you don't, I don't see how writing some long pain in the butt equation will help you know how to do the problem.

Homework Statement A particle of mass m is subject to a force F(x) = −kx^−2 (1) that attracts it toward the origin. (a) Determine the potential energy function U(x), defined by F(x) = − d U(x)/dx. (b) Assuming that the particle is released from rest at a position x0, show that the time t...

I mean I have Anaconda, but I'm looking for resources that will help me learn how to use it properly to plot and do other things I may need for school, if those exist.

Hi, I was just wondering if there were any good resources/sites for learning to plot and solve differential equations and any other math for that matter, specifically in Python? The physics program at ASU is great but we aren't really given any class time to learn how to program, it's all on our...

Okay, I think I get it. It just gets confusing to me when they throw so many different r(t)s and rs in there. Thanks.

I'm not sure I get it, could you explain it in the sense of the book I am using, on the right side of the page.

I'm having trouble with with understanding what this is, our text, Astronomy: a physical Perspective by Kutner, uses R(t). I understand r(t) is the distance between two objects at a point in time, but what is the scale factor big R(t)?

Awesome. Thank you

So, just a little clarification, I did a little research online, is M the magnetic strength of each pole and r, I take it is the distance? Thanks btw.

Not for a class or anything, just out of curiosity, how would you calculate the current in a solenoid, not given a magnetic field, but just using a bar magnet? I know it will just be some form of Faraday's law. E=N(dphi/dt). Maybe not. I'm imagining all I'm really missing is how to calculate the...

I was assigned problem 4, the apparent magnitude was given in problem 3. I should have just read that, thanks though.

1. (a) What is the distance modulus of the Sun? (b) What is the Sun’s absolute magnitude?2. I found the distance modulous using 5log(4.84E-6/10) to be -31.6. I feel like I need the apparent magnitude to get the absolute, my teacher is very vague about what we are given to use. Is there a way...
