Yes another typo lol...Thank you so much, all your help is greatly appreciated!

Yes, apologies it was a typo it is 1.6*120=192 W. If you could please check the rest of my work it would be great because this problem has been a pain in my side for a couple of days (:

sorry microfarad (µF)

I just wanted to know if I was correct. Whether my process of thinking was correct and the numbers backed it up. The power factor is just p=1/2 VI cosϕ, correct? so is it then 1/2 [120*1.8 cos (0)]= 96 W.

Homework Statement A series RLC circuit has R=75 ohms, C=20 mF and a resonance frequency of 5.0 kHz. (i) What is the value of inductance? (ii)What is the impedance of the circuit at residence? (iii)What is the rms current at resonance if the rms voltage of the power supply is 120 V? (iv) How...

Homework Statement A vendor hangs an 8.6kg sign in front of his shop with a cable held away from the building by a lightweight pole. The pole is free to pivot about the end where it touches the wall, Homework Equations T*L*sinΘ = mgd where d is the distance from the sign to the wall and L...

Yeah I actually just figured it out, that is the only thing I messed up... Should be F=mv^2/r (.4)g=v^2/r (9.8*.4)r=v^2 3.92*18=v^2 v=8.4m/s Thanks for helping you guys

OK well if I am solving for the velocity of the moving coaster, how would I do that because I've drawn the diagram with forces and I don't see it.

Homework Statement A roller coaster car is going over the top of a 18-m- radius circular rise. At the top of the hill, the passengers "feel light," with an apparent weight only 60% of their true weight. How fast is the coaster moving? Homework Equations I think F=mv^2/ (r) F=ma The Attempt...
