A resistor is wired to a battery in a circuit and dissipates a power P1 as heat. A second battery, with the same voltage, is added in series with the first battery, leading the resistor to dissipate a power P2 as heat. How much does the resistor dissipate with two batteries, relative to with one battery, or in other words, what is the ratio P2/P1?

1) A small steel block and a magnet rest on a horizontal frictionless table. The steel block weighs 0.07N and the magnet is fixed to the table. The force acting on the steel block by the magnet is inversely proportional to the square of the distance between the steel block and the magnet. When the block is 26cm away from the magnet, the force becomes 0.145N. If the block starts its motion from rest at this position, what is the magnitude of the velocity of the block when it is 9.5cm away from the magnet?
