6. You get to your dive site and park the car. You put on your gear and get ready to enter the water. But first you check your scuba tank. It is filled to a pressure of about 25,000 kPa at 300 K. The volume of the tank is 25 L. You begin to wonder: If pressure remains constant, what would happen to the volume of gas in the tank if its temperature increased? (6 points) a. Which of the four thermal processes describes the temperature-volume relationship at constant pressure? (3 points)

b. Write the equation for this process. Hint: Think about the first law of thermodynamics. (3 points)

If a textbook weighs 37.2 n on venus, and the book has a mass of 4.4 kg, what is the strength of gravity on venus? 8.9 m/s28.9 m/si don't have enough information,9.8 m/s2

Suppose water is leaking from a tank through a circular hole of area ah at its bottom. when water leaks through a hole, friction and contraction of the stream near the hole reduce the volume of water leaving the tank per second to cah 2gh , where c (0 < c < 1) is an empirical constant. a tank in the form of a right-circular cone standing on end, vertex down, is leaking water through a circular hole in its bottom. (assume the removed apex of the cone is of negligible height and volume.) (a) suppose the tank is 20 feet high and has radius 8 feet and the circular hole has radius 2 inches. the differential equation governing the height h in feet of water leaking from a tank after t seconds is dh dt = − 5 6h3/2 . if the height of the water is initially 8 feet, how long will it take the tank to empty? (round your answer to two decimal places.)

The seven sisters, seven stars located more than 400 light-years away in the taurus constellation can be seen here with venus and another constellation, orion. the seven stars stay grouped together but seem to move, like the planet venus. why do stars seem to move like planets in the night sky?
