Sorry, forgot to attach a picture of the circuit. Will do that soon.

Homework Statement The circuit used in this problem is attached as an image. I made this in gEDA (the circuit is from the homework problem, I just didn't feel like using a scanner to get the image) The 2-microfarad capacitor shown in the circuit attached is fully charged by closing switch...

Homework Statement Find the moment of inertia of a right circular cone of radius r and height h and mass m Homework Equations I = ∫r2 dm V = 1/3*π*r2*h The Attempt at a Solution Assume density is p dm = p dv divide both sides by dr dm/dr = p dv/dr dm/dr = p (d/dr * 1/3*π...

Thanks! And I think my handwriting might be worse.

Yes please!

Does anyone have a formula for the current in a series RCL circuit, if I have the: resonance frequency, current at resonance, capacitance (only one resistor, one capacitor, and one inductor), the voltage of the battery attached, and resistance?

When I said what direction is the magnetic field flowing, I meant by convention, as in, if it's flowing clockwise, then if I wanted to use the other right hand rule, what direction would I point my middle finger (which represents the magnetic field)?

Thanks! And the online thing doesn't let us (for most questions) put in scientific notation

Homework Statement In the figure (see attached) what is the velocity of the charged particle to the nearest tenth of a m/s that will allow it to travel undeflected through the crossed magnetic field if E = 6852 N/C and B = 3.6 T? Homework Equations F = E*q + q*V*B The Attempt at a...

Hi everyone, If I have a current going up a straight wire, and use the right hand rule (the one where you stick your thumb up and curl your other four fingers), then the magnetic field is in the right direction, correct (my fingers curl to the right)? However, according to this video: It's...

okay, thanks

I see part of it, but shouldn't the current in I3 flow the other direction?

Now it is :smile:

Homework Statement I have this circuit diagram (see attached), and the question is: Which of the following equations is Kirchhoff's first rule as applied to the above circuit? With the answers: I1 + I2 + I3 = 0 I1 - I2 + I3 = 0 I1 + I2 - I3 = 0 I1 - I2 - I3 = 0 (it's multiple...

"converting" tangential momentum to angular momentum If someone is running and jumps onto a merry-go-round, momentum is still conserved, correct? (ignoring friction). So, would the momentum of the person while they were running be the same as the angular momentum of the merry-go-round after...
