Hey so, I was just wondering: If Carbon-14 (6 protons, 8 neutrons) decays into an electron, a neutrino, and Nitrogen 14 (7 protons, 7 neutrons) How is charge conserved? I get that nucleons are conserved, but if nitrogen-14 is neutral, then it has 7 protons and 7 electrons, versus Carbon...

Okay, this is not a homework question, but a conceptual question already answered in the book. Problem: Suppose the Earth's orbit around the sun is perfectly circular. What is the work done by the gravitational force of the sun on the Earth through a small displacement over a small time...

Ahh thank you guys so much! This is very helpful. I think I'll probably just be lacking mostly in some advanced inorganic/organic knowledge, but if the GRE test doesn't go into that much detail then I should be fine. Thanks again!

GRE Chemistry subject test preparation help Hello! I am a physics major with a passion for chemistry that I might want to pursue. Unfortunately I do not have time to complete both a physics degree and a chemistry degree in the 1.5 years I have left as an undergrad. I would however...

Homework Statement A long copper rod of radius R has uniformly distributed free current I. Find the value of H inside and outside the rod Homework Equations ∫Hdl=I(free enclosed) The Attempt at a Solution Copper is diamagnetic so the magnetization will be circumferential and...

Homework Statement A thick slab extending from z=-a to z=+a carries a uniform volume current J=J (in the x direction) Find the magnetic field, as a function of z, both inside and outside the slab. Homework Equations ∫Bdl=(µ0)Ienc The Attempt at a Solution I am not sure how to...

Ah! Thank you, that makes sense.

Homework Statement Suppose that the magnetic field in some region has the form B = k z ˆx. (where k is a constant). Find the force on a square loop of side a, lying in the yz plane and centered at the origin, if it carries a current I flowing counterclockwise when looking down the x...
