Ok, so I found the two values for Q1 and Q2 (.49 and 1.51, respectively) and used that to solve for voltage. Thanks!

I considered that and tried to just put 1Q0 as the answer, but that was wrong.

Yes it does. Do I need to use that?

Homework Statement Two identical capacitors are connected in parallel and each acquires a charge Q0 when connected to a source of voltage V0. The voltage source is disconnected and then a dielectric (K=3.1) is inserted to fill the space between the plates of one of the capacitors. Assume that...

I used the v^2 = 2gh equation to get v=26.9295 I then plugged this into the F=p/t equation: F = 0.145(39-26.9295) / 0.001 F=1750.22 and that was wrong - and I don't have anymore attempts left on that part, apparently the correct answer was 6900 N. For the second part I need to find the...

Ok, I tried using x=xo + vot + 1/2at^2 to find the initial velocity after leaving the bat, but I got a huge number: 37=0 + Vo(0.001) + 1/2 (39/.001)(.001)^2 Vo=36980.5 m/s I'm sorry, for some reason I'm just not getting it tonight. I also thought about using conservation of energy to find V and...

How would you do that?

Homework Statement A 0.145 kg baseball pitched horizontally at 39.0 m/s strikes a bat and is popped straight up to a height of 37.0 m. (a)If the contact time between bat and ball is 1.0 ms, calculate the magnitude of the average force between the ball and bat during contact. (b)Find the...

Is it allowed to have T1 in the answer? I didn't think it was because it said in terms of some or all of the variables m, θ1, and θ2, as well as the magnitude of the acceleration due to gravity g. It never mentions T1.

I tried that, but I kept getting an answer where T1 was equal to something that had T1 in it. Such as: T1 = (mg - T1cosθ1tanθ2) / sinθ1 I got that when I plugged T2 = T1 (cosθ1)/(cosθ2) into the y component.

Homework Statement A chandelier with mass m is attached to the ceiling of a large concert hall by two cables. Because the ceiling is covered with intricate architectural decorations (not indicated in the figure, which uses a humbler depiction), the workers who hung the chandelier couldn't...

Homework Statement What is the solubility (gram/liter) of Cr(OH)3 (103.02 g/mol) in a solution buffered at pH = 8.673? The pKsp of Cr(OH)3 is 30.220. Homework Equations Ksp = [Cr][OH]^3 Cr(OH)3 -> Cr + 3OH The Attempt at a Solution I have already solved that Ksp = 6.0256 E -31...
