Space probes may be attached to their launchers by exploding bolts, which can be used to separate the parts after takeoff. suppose a 4800-kg satellite uses this method to separate from the 1400-kg remains of its launcher, and that a total of 4850 j of energy is supplied to the two parts by the explosion. this process is "perfect" in the sense that the energy is transferred entirely to the motion of the system, rather than any deformations or other internal energy changes.

As shown in fig. p3.64, a closed, rigid tank fitted with a fine-wire electric resistor is filled with refrigerant 22, initially at 2108c, a quality of 80%, and a volume of 0.01 m3. a 12-volt battery provides a 5-amp current to the resistor for 5 minutes. if the final temperature of the refrigerant is 408c, determine the heat transfer, in kj, from the refrigerant.

Light from the sun reaches the earth in 8.3 minutes. the velocity is 3.00 x 10^8 m/s. how far is earth from the sun? i know how to get to d = (3 x 10^8 m/s)(498 sec). i just don't know how to get from there to the answer being 1.5 x 10^11 m.
