(I tried to tag them but it didn't work =.=. There! Now other peoplez can see da bootifulness~

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.

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation

What is the acceleration of a spaceship that is initially at rest and then speeds up to 220 m/s in 20 seconds
