Complete these sentences. if a roller coaster train has a potential energy of 1,500 j and a kinetic energy of 500 j as it starts to travel downhill, its total energy isj. once the roller coaster train gets closer to the bottom of the hill, its kinetic energy increases to 1,100 j, and its potential energy decreases to j. when the train reaches the bottom of the track and is traveling along the ground, its kinetic energy isj.

Along wire of diameter 1 mm is submerged in an oil bath of temperature â 31°c. the wire has an electrical resistance per unit length of 0.01 Ď/m. if a current of 103 a flows through the wire and the convection coefficient is 500 w/m2¡k, what is the steady-state temperature of the wire? from the time the current is applied, how long does it take for the wire to reach a temperature that is within 1°c of the steady-state value? the properties of the wire are 8000 kg/m3, 500 j/kg¡k, and 20 w/m¡k.
