You guys made me feel much better about it :-) I can guarantee my fiance is more than supportive and would probably put my dreams even ahead of his own (although I won't let him!) and I'm positive he'd help with a baby when the time comes. Thanks for boosting my confidence

I'm debating pretty heavily with myself whether to continue with my education. I really would like to but the main problem is my age and that fact that I'm a woman with a body clock to consider. It will have taken me 8 years to get my B.S. in Physics minoring in Mathematics in Spring 2013. I...

Homework Statement Consider a sound wave in air of density 1.2 kg/m3. The displacement wave has the form s(x,t)=smaxcos(kx-\omegat) where k=8.79rad/m, \omega=3021.6 rad/s and smax=2.51 x 10-7m. Calculate the sound pressure \DeltaP(x,t) of this wave at x=0.282m and t=0.00137s. Answer in units...

awesome! thanks so much! And yeah I double checked the resistivity and the units given in the problem and I posted it correctly...This problem isn't very close to reality then huh? I didn't know that about silver though! You learn something new everyday!

ok so what you're saying is the resistance is [(resistivity)x(length of the wire)]/(cross-sectional area of the wire) ? and for turns density: the length of the wire to make one turn around the solenoid is the circumference of the solenoid. the length of the solenoid isn't given however the...

A solenoid of radius 0.0523m is made of a long piece of wire of radius 0.002432m, length 54.0m, and resistivity 7.4x10^-9 \Omegam. The solenoid is closely wound with a single wire thickness. The permeability of free space is 1.25664x10^-6 Tm/A. Find the magnetic field at the center of the...
