A speed skater moving across frictionless ice at 9.0 m/s hits a 5.1m -wide patch of rough ice. She slows steadily, but thereafter continues for 22 m in 4 seconds. What is her acceleration on the rough ice? Show all kinematic motion graphs.

The diagram shows four locations in the electric field of a positive point charge m. at which location is the electric potential the greatest.

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.
