Textbook Question

Chapter 18, Problem 63PCE

Predict/Explain (a) An ideal gas is expanded slowly and isothermally. Does its entropy increase, decrease, or stay the same? (b) Choose the best explanation from among the following:

I. Heat must be added to the gas to maintain a constant temperature, and this increases the entropy of the gas.
II. The temperature of the gas remains constant, which means its entropy also remains constant.
III. As the gas is expanded its temperature and entropy will decrease.

An electric power station that operates at 30 KV and uses a 15:1 set step-up ideal transformer is producing 400MW (Mega-Watt) of power that is to be sent to a big city with only 2.0% loss. What which is located 270 km away is the resistance of the Two wires that are being used? 52

Slink, from Toy Story, is a slinky dog whose middle section is a giant spring with a spring constant of 10.9 N/m. Woody, who has a mass of 0.412 kg, grabs onto the tail end of Slink and steps off the bed (as shown in figure A) with no initial velocity and reaches the floor right as his velocity hits zero again (as shown in figure C).

The character Min Min from Arms was a DLC character added to Super Smash Bros. Min Min’s arms are large springs, with a spring constant of 8.53 ⋅ 10^3 N/m, which she uses to punch and fling away her opponents. Min Min pushes her spring arm against Steve, who is not moving, compressing it 1.20 m as shown in figure A. Steve has a mass of 81.6 kg. Assuming she uses only the spring to launch Steve, how fast is Steve moving when the spring is no longer compressed? As Steve goes flying away he goes over the edge of the level, as shown in figure C. What is the magnitude of Steve’s velocity when he is 2.00 m below where he started?
