Solve the following problems:

Problem I: What is the voltage across six 6.0V batteries when they are connected five in parallel with one another and this combination wired in series with the remaining one? Assume all batteries are ideal unless told otherwise.

Problem II: What is the emf of a battery with a 0.15ohm internal resistance if the battery delivers 2.0A to an externally connected 5.0ohm resistor?

Please explain clearly with details so that I can follow.

Size of the tank and the final pressure in the tank : An insulated rigid tank is divided into two equal parts initially by a partition. Initially, one part contains 5 kg of air at 800 kPa and 75° C and the other part is evacuated. The partition is now removed and the air expands into the entire tank. De..

What are the charges on the inner surfaces of the shell : A conducting spherical shell of inner radius a = 0.8 m and outer radius b = 1.0 m carries a charge of QC = -20 µC. What are the charges on the inner surfaces of the shell

Determines work done and heat transfer : For the cylinder-piston shown, piston is initially resting on the lower stops. The cylinder contains 1 kg of water at 1 bar and x = 0.64. A pressure of 3 bars is required to move the piston. The system is now heated until the water reaches 600° C. Sh..
