That worked out great! I used the Pythagorean theorem to fix the relationships and then eliminate all the trig all together. Thanks for the help!

[SOLVED] Snells Law (Changing view of an object through different materials) Homework Statement A shallow glass dish is 4.0cm wide at the bottom, as shown in the attached figure. When at observer's eye is positioned as shown, the observer sees the edge of the bottom of the empty dish. When...

That would make sense to me, and of course it would agree with what was previously stated. Gravity on any of those planets would merely affect the amplitude which would not change the period of the oscillation and not change the mass requirements according to the problem.

Thanks, that makes perfect sense to me. Now that I think about it, the equilibrium point will change but the change of the mass on the period will not since the spring constant remains the same at both locations.

[SOLVED] Harmonic Motion of Pendulum on Mars Homework Statement The problem is as follows: The acceleration due to gravity on Mars in 3.7m/s^2. A mass is suspended from a spring with a force 10 N/m. Find the mass suspended from this spring that would result in a one second period on Earth...

No problem. I just wanted to really make sure that my concepts were correct. I can always recheck the number as I write it down in my actual homework. Thanks for all the help! Greatly appreciated.

Alright... that took a few minutes to make sense of. Allow me to explain my recalculations: \Phi = BACos(\Theta) Emf = -N(\Delta\Phi/\Deltat) Thus: \Delta\Phi = (0.15T*(pi*(.15)^2)) - (0.2T*(pi*(.15)^2)) = -0.003534 EMF = -(5 Turns)*(-0.003534)/3s = .00589V The average current...

[SOLVED] Average Current Through A Coil Over An Interval Homework Statement The problem comes from a homework assignment I have. It has to deal with average current flowing through a wire over an interval. It is stated as follows: A five-turn circular coil of radius 15cm is oriented with its...
