Awesome thanks! :)

So if it's nowhere near the solenoid, I don't use the solenoid equation, B=(m0NI)/l? Is that what you're saying? Would I use B=(m0/2pi)(I/d) since the wires are in parallel right there and not all twisted up like a solenoid? The d value would be either d1 or d2, depending upon which I chose to...

Yes it was. I thought I posted it already. Sorry, here it is

Homework Statement A pair of wires carry a current I=2.4 A to and from a solenoid. The solenoid contains 600 coils of wire wrapped in a cylinder 15 cm long and 1 cm in diameter. a.) What is the magnitude and direction of the magnetic field at point A d1= 5 mm from the near wire and d2= 7 mm...

Thank you guys so much!

Sorry I didn't mean to post that twice. So I got approx. 13.0034 for the height of the building. Is that correct?

So it's 0 m/s instead of 12.4 m/s?

So it's 0 m/s instead of 12.4?

I have y=y0+vyo(t)+.5at^2 Then I plugged in y=0+12.4t+.5(-9.8)t^2 Which then becomes y=12.4t+.5(-9.8)t^2 I then plugged in the time, so y=12.4+.5(-9.8)(1.6290)

I got the time as approx. 1.6290. Is that right? I plugged the time into the vertical equation and got approx. y=-5.8067

Homework Statement A ball thrown horizontally at 12.4m/s from the roof of a building lands 20.2m from the base of the building. How tall is the building? Homework Equations I think I'm supposed to use these: horizontal motion: x=x0+vx0t vertical motion: y=y0=+vy0(t)-.5at^2 The Attempt at a...
