A popular wilderness survival tool is a hand held piston where you put dry bits of plant matter into the piston, put the plunger into the top of the piston, and then hit the piston plunger as hard as you can, causing the gas to contract suddenly, which increases the temperature of the gas inside the gas so fast, that it gets hot enough to make the plant matter catch fire. You have a fire piston with a volume of diatomic gas (air) of 0.2 L, a pressure of 102 kPa and a temperature of 293 K. You hit the piston, and the gas inside heats up to 506 K, which is just hot enough to make the plant matter in the bottom of the piston combust. Because you compressed the piston so quickly, this is an Adiabatic process. Required:
Use the fact that this was an adiabatic process, as well as the Ideal Gas Law, to find the final pressure and volume of the gas in the piston right after you compress the piston.

If you were to drop a rock from a tall building, assuming that it had not yet hit the ground, and neglecting air resistance. what is its vertical displacement (in m) after 6 s?

Which is the best for showing percentages of different types of cars sold(gas hybrid , electric , other ) in the united states ?

Aplane flies a distance d from west to east at a constant speed vp , with respect to the air in a time twe . on the return trip, the plane flies a distance d from east to west at a constant speed vp , with respect to the air in a time tew . on both trips the wind blows from west to east at a constant speed va , with respect to the ground 1) what is tew in terms of vp, va, and d, as needed? tew=dvp tew=dvp+va tew=dva tew=dvpâ’va tew=12dvp tew=12dvp+va tew=12dvpâ’va your submissions: b submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 2) what is twe in terms of vp, va, and d, as needed? twe=dvp twe=dvp+va twe=dva twe=dvpâ’va twe=12dvp twe=12dvp+va twe=12dvpâ’va your submissions: d submitted: saturday, january 26 at 6: 49 pm feedback: feedback will be given once all questions have been attempted and the grade cluster button has been pressed. 3) assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is va, the speed of the wind with respect to the ground? va = 100 miles/hr va = 575 miles/hr va = 200 miles/hr va = 175 miles/hr va = 975 miles/hr 4) once again, assuming d = 2300 miles, vp = 400 miles/hr, and twe = 4 hours, what is tew, the time it takes the plane to fly a distance d miles from east to west? tew = 5.75 hours tew = 11.5 hours tew = 7.67 hours tew = 8 hours tew = 10.2 hours
