The diagram below represents two carts with low-friction wheels. A magnet is mounted on each cart. The magnet on cart 2 is twice as strong as the magnet on cart 1. Both carts are kept at rest by the attached spring scales. The sprint scale on the left reads 10 N. What does the spring scale on the right read, in Newtons? Explain your reasoning.

An ice-making machine inside a refrigerator operates in a carnot cycle. it takes heat from liquid water at 0.0 degrees celsius and rejects heat to a room at a temperature of 19.2 degrees celsius. suppose that liquid water with a mass of 76.3kg at 0.0 degrees celsius is converted to ice at the same temperature. take the heat of fusion for water to be l_f = 3.34*10^5 j/kg. how much energy e must be supplied to the device? express your answer in joules.
