Homework Statement 6550 J of electrical heat is added to a constant pressure calorimeter containing 125 grams of water at 22.6 ◦C. If the final temperature of the calorimeter is 33.7 ◦C, the heat capacity of the calorimeter (including the water) is: Homework Equations I think it is...

so for delta \Phi it would be (14.4x10^-6)-(0)?

Homework Statement A solenoid with a length of 25.0 cm, radius 1.60 cm and 5500 turns carries a current of 1.50 A. A small coil of radius 1.05 cm and 130 turns is placed at the center of the solenoid with its axis in the same direction as that of the solenoid. A 470 ohms resistor is connected...

Your answer has helped me a great deal! So if my understanding is correct, the change is -200, and i would multiply this by -1.602x10^-19. Since it is an external force the sign changes to a +3.2x10^-17. I am not sure if my understanding is right, but that's the first thing that came to mind...

The question I am having trouble with shows an image of 2 different conductors, one is at +300 volts, while the other is -600 volts with a few lines going in between which circle around. The points on the equipotential surface are on lines labeled as a (which lies on a -200V line) and the other...
