Hello everyone. I was just wondering is anyone knew an example of a physical device with a)both inductance and resistance b)capacitance, resistance, and inductance. I looked these up on wikipedia and I got that an example for b) would be a radio tuner, is that right? Plus, I can't get a)...Any help?

OKie, so I guess you gave up on me...any other takers...?

okie, so it's either 2, or the square root of 8, or maybe 7...? I am sorry, I'm seriously physics retarded!

Okie, I understand that that's the correct equation, but how do I distinguish between the different axes??

would you use the same equation for a particle as you would for an sphere? I know that the rotational inertia is equal to mR^2. Is that what you mean?

This is the last problem that is frustrating me... A wheel, starting from rest, rotates with a constant angular acceleration of 1.20 rad/s2. During a certain 5.00 s interval, it turns through 32.5 rad. (a) How long had the wheel been turning before the start of the 5.00 s interval? (b) What...

I absolutely suck at physics. Here is the question I'm stuck on: The masses and coordinates of four particles are as follows: 69 g, x = 2.0 cm, y = 2.0 cm; 38 g, x = 0, y = 4.0 cm; 21 g, x = -3.0 cm, y = -3.0 cm; 24 g, x = -2.0 cm, y = 4.0 cm. What are the rotational inertias of this collection...

OKie, I am having a bit of trouble with this problem... The flywheel of a steam engine runs with a constant angular velocity of 160 rev/min. When steam is shut off, the friction of the bearings and of the air stops the wheel in 1.2 h. (a) What is the constant angular acceleration, in...
