Homework Statement This is not really a question, just a concept I am trying to understand. I understand changing magnetic field induces an electric field - but how does it do this? Homework Equations The Attempt at a Solution I figure since the changing magnetic field would...

Great, thanks for all the help guys :)

Consider each loop separately. Assign a current to each branch (doesn't matter the direction). Set up a junction rule equation based on the sum of currents and set up two or more loop rules. Isolate and solve for unknown variables. In your specific case, I1 + I2 = I3

Actually, I think I just figured it out: If I express them in terms of E and energy stays constant for both: r2 / r1 = m2v2 / m1v1 = m2sqroot(2E/m2) / m1sqroot(2E/m1) r2 / r1 x sqroot(m1) = sqroot(m2) m2 = (r2 / r1 x sqroot(m1))^2 m2 = 13 u Is that correct?

Okay, so I am still totally confused. I know r = mv / Bq, the magnetic field and the charge are constant but the mass and velocity are NOT constant, but we aren't given the velocity. So if I set up a ratio: r2/r1 = m2v2/m1v1 and isolated for m2 (r2/r1 x m1v1) / v2 = m2 r2m1v1/r1v2 = m2 Do I...

I thought so too, but the textbook states that if the mass is different of the two charges, than, when they pass through a potential difference, the velocity is not the same. If I follow the logic you provided, I end up with the ratio: r2/r1 = m2/m1 m2 = r2/r1 x m1 m2 = 12.48 u When the actual...

According to me, density is mass / volume. When you heat up a liquid and turn it into gas, its density increases because its volume increases. However, different liquids have different heat capacities (the amount of heat required to raise the temperature by 1 degrees celcius), therefore, the...

Homework Statement Natural carbon consists of two different isotopes. The isotopes have different masses, which is due to different numbers of neutrons in the nucleus; however, the number of protons is the same, and subsequently, the chemical properties are the same. The most abundant isotope...
