A steel bucket contains 4 liters of water at 12C. An electric immersion heater rated at 1400 Watts is placed in the bucket. Determine how long it will take for water to heat to 70C. Assume that the empty bucket weighs 1.1 kg. The specifi c heat of steel is 0.46 kJ/(kgC). Use an average specifi c heat of water of 4.18 kJ/(kgC). Disregard any heat loss to the surroundings.

Which of these describe conduction transfer of heat between two objects that are touching transfer of heat by the actual movement of war matter the process in which energy is imitated by one of the object transmitted through space and absorbed by another a process in which energy is released by the molecules breaking apart

(a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
