Suppose a 10 ml beaker and a 100 ml beaker are both filled with water, and that the water in both beakers is the same temperature. which statement below about the water in the two beakers is true? a. the two beakers of water contain equal amounts of heat b. the larger beaker of water contains more heat than the smaller beaker c. the smaller beaker of water contains more heat than the larger beaker d. it is not possible to determine which beaker of water contains the most heat because heat cannot be measured

Electric field of the earth. the earth has a net electric charge that causes a field at points near its surface equal to 150 n> c and directed in toward the center of the earth. (a) what magnitude and sign of charge would a 60-kg human have to acquire to overcome his or her weight by the force exerted by the earth’s electric field? (b) what would be the force of repulsion between two people each with the charge calculated in part (a) and separated by a distance of 100 m? is use of the earth’s electric field a feasible means of flight? why or why not?

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.
