Consider dropping a ball from rest. This ball moves from astate of high gravitational potential energy to one of lowgravitational potential energy as it falls to the ground. Similarly, charges move from a state of high electric potentialenergy to one of low electric potential energy. Mustang Sally just finished restoring her1965 Ford Mustang car. To save money, she did not get a newbattery. When she tries to start the car, she discovers that thebattery is dead and she needs a jump start. While unhooking thejumper cables, the positive and negative cables almost touch and aspark jumps between the ends of the cables. This spark is caused bythe movement of electrons through the air between the batteryterminals. In what direction are the electrons traveling?

The key to stability is feedback between the reservoir and the fluxes into and/or out of the reservoir. assume that the rate of outflow from a reservoir depends on the size of the reservoir according to the following relationship: outflow rate= k x (size of reservoir), where k is a constant. a reservoir of water has a volume of 5000 liters, and the rate of outflow at steady state is 25 liters per minute. what is k? (give both the numerical value and its units.) what is the residence time? what is the relationship between k and the residence time?

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
