Oh. Okay. I missed that. Thank you so much!

I think I must have forgotten to square "I"...your figures are correct. But then don't you also have to take into consideration that when you do 1/r1 + 1/r2 , that it equals 1/Req? ?

I have my two equations, but I'm having trouble putting the two equations together. I have r1 + r2 = 7 and 1/r1 + 1/r2 = 1/52

Homework Statement When two unknown resistors are connected in series with a battery, the battery delivers 260 W and carries a total current of 5.00 A. For the same total current, 35.0 W is delivered when the resistors are connected in parallel. Determine the values of the two resistors...

Alright thanks so much! I understand how to do it now!

Okay. I think I got it...part of my problem was that I didn't have my calculator set in degrees. The other part of my problem was that I had originally gotten the torque from the jack, not from the car. Thank you for your help!

Homework Statement A cylindrical fishing reel has a mass of 0.85 kg and a radius of 4.5 cm. A friction clutch in the reel exerts a restraining torque of 1.6 N·m if a fish pulls on the line. The fisherman gets a bite, and the reel begins to spin with an angular acceleration of 66 rad/s2. a)...

So you subtract the lengths to get from the jack to the rear wheels?

Homework Statement A mechanic jacks up a car to an angle of 10.0° to change the front tires. The car is 2.95 m long and has a mass of 1150 kg. Its center of mass is located 1.12 m from the front end. The rear wheels are 0.40 m from the back end. Calculate the torque exerted by the car around...
