Ahh ok thanks

yeah i know the letters...the charge is -0.010C, my page is not vertical...

A stone is moving constantly in a horizontal motion in a uniform magnetic field in the direction pointing into the page. The field's strength is 1.7T. How fast does the stone have to move in order for it to remain moving horizontally without any vertical deviation? For this quesion, using...

If I have two different charges and I'm told to calculate net force, do I just use F=KQ1Q2/r^2 or Fnet=F1+F2... Please explain.

Wouldn't I just add 1/40+1/900=38.29ohms?

I found out the answer was to be 1.5*40/940. I have no idea how the person got 40/940 can someone please explain

Homework Statement Suppose that a person's body resistance is 900ohms. a) what current passes through the body when the person accidentally is connected to 110V? b) if there is an alternative path to ground whose resistance is 40 ohms, what current passes through the person? c) if the...

ok, i finally got this figured out, thanks for the help

I got 7.14amps with the 25ohm resistor and 6.9amps without the 25ohm resistor.

If the 25ohm resistor in figure19-39 were shorted out, what then would be the current through the 10ohm resistor?

Homework Statement How would you calculate the voltage at a specific resistor given that it's a parallel circuit.

I have no idea, can someone clarify this please?

that equation doesn't give me a velocity of 0.3445m/s. mgh=1/2mv^2 (1kg)(9.8m/s^2)(1.1m)=1/2(1kg)(v^2) =4.64m/s Is it 4.64 m/s?

yeah i got that answer (I don't know if it was right though since I don't have the answer key). How did you find V again? I have no idea what '-wAsin(wt) and from x=Acos(wt)' was.

it's for tension
