Block A rests on a horizontal tabletop. A light horizontal rope is attached to it and passes over a pulley, and block B is suspended from the free end of the rope. The light rope that connects the two blocks does not slip over the surface of thè pulley (radius 0.080 m) because the pulley rotates on a frictionless axle. The horizontal surface on which block A (mass 3.70 kg) moves is frictionless.

please help me correct the following

Given two batteries: one with voltage Vand internal resistance r1; another with also voltage Vand internal resistance r2. Which of the following is true if we connect them in parallel the positive terminal of one connected to the negative of the other? O The answer cannot be found on the other choices. The total voltage will be V, while the total internal resistance is (r1-1 + r21)1. No voltage will remain, while the total internal resistance is (rıi -1 + r2 O The total voltage will be 2V, while the total internal resistance is (r11 + r2)1.

The two figure panels show two ways to connect a real (non-ideal) voltmeter and a real ammeter in a circuit to calculate the resistance R. The internal resistance of the voltmeter is Rv and the internal resistance of the ammeter is Ra. The current flows from left to right in both panels, and the potential difference Vac between points a and c in both panels is the same. In panel (a) 
the voltmeter reads Vac = 12.1 V and the ammeter reads I1 = 0.098 A. In panel (b) the voltmeter reads Vab = 12.0 V and the ammeter reads I2 = 0.100 A.   I need help with Part E.
