I can't make an assumption on the mass. I emailed my prof: "Think of small masses at Celeste's feet and head and what would be the forces on them. The difference in the forces is the same even if the points are not attached. You're calculating a difference, so the exact masses you use...

Homework Statement In the Schwarzschild Slalom, brave athletes dive from a platform orbiting at a distance of 1 AU from the singularity at the centre of a black hole with a mass of 10 MSun. The competitor who can get closest to the singularity, and survive, wins the event. (The rules state the...

Is not thermal energy also related to the potential energy of the molecules?

Will be obtaining my BSc in microbiology and immunology from UBC next May, and then hopefully in September 2011, I will be in med school or touring Europe and getting absolutely smashed a couple (or 365) more times before entering med school.

This isn't really a homework question per se. I'm studying for my MCAT and I'm having trouble trying to firmly get down some of the concepts in thermodynamics. As far as I know, heat is the means of energy transfer that isn't work from one substance to another due to a difference in...

Homework Statement A small 2.0-mm-diameter circular loop with R = 0.020 Ohms is at the center of a large 100-mm-diameter circular loop. Both loops lie in the same plane. The current in the outer loop changes from +1.0 A to -1.0 A in 0.10 s. What is the induced current in the inner loop...

A general rule of thumb is to use the least amount of sig figs as the values given to you in the question.

No, all of the carbon found in nature are isotopes of each other. You can't really call anyone of them 'standard' because they all exist. You can call one of them the most common.

Did they give you a battery voltage or emf?

It's asking for the potential energy, not the potential.

Right.

Show your work, we can't help you if we don't know where you went wrong.

Apparent frequency is the frequency of the sound you hear due to the Doppler effect (f').

N-12 doesn't exist. C-12 is common.

2x\sqrt{3x-1} \neq 12x^2 - 4x
