Suppose object A (2 kg) is at rest and object B (10 kg) runs into it with high speed. What is the likely result?
A.
Object A will remain at rest.
B.
Object B will come to a stop.
C.
Object B's final momentum will be larger than its initial momentum.
D.
Object A will move in the direction of object B's velocity; object B will continue in that direction with a final speed less than its initial speed.

Along wire of diameter 1 mm is submerged in an oil bath of temperature ∞ 31°c. the wire has an electrical resistance per unit length of 0.01 ω/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.
