A thin spherical shell with radius R1 = 4.00 cm is concentric with a larger thin spherical shell with radius 7.00 cm. Both shells are made of insulating material. The smaller shell has charge q1 = +6.00 nC distributed uniformly over its surface, and the larger shell has charge q2 = -9.00 nC distributed uniformly over its surface. Take the electric potential to be zero at an infinite distance from both shells. A. What is the electric potential due to the two shells at the following distance from their common center: r= 0? B. What is the electric potential due to the two shells at the following distance from their common center: r= 5.00 cm? C. What is the electric potential due to the two shells at the following distance from their common center: r= 8.00 cm? D. What is the magnitude of the potential difference between the surfaces of the two shells? E. Which shell is at higher potential: the inner shell or the outer shell?

The magnitude of the amount of energy released by burning a fuel source, measured in energy per unit mass, is called its fuel value. note that the fuel value is the negative of the isobaric specific heat of combustion for the fuel. if all the energy obtained from burning 1.23 pounds of butane with a fuel value of 10.85 kcal/g is used to heat 128.0 kg of water at an initial temperature of 18.3 °c, what is the final temperature? note that 1 lb = 453.6 g.
