A tank holds 125 moles of argon gas (atomic mass = 6.633521 × 10^-26 kg) at a pressure of 101300 Pa and a temperature of 301 K. Recall that the number of gas molecules is equal to Avagadros number (6.022 × 10^23) times the number of moles of the gas. Required:
a. What is the volume of the tank?
b. How much kinetic energy is contained in this gas?
c. What is the average speed of one of the argon atoms?
d. The escape speed of Earth is 11200 m/s. What temperature would the argon gas need to have so that the average speed of the gas atoms was equal to this escape speed?

Aman does 500 j of work pushing a car a distance of 2 m. how much force does he apply? assume there is no friction. a. 250 n b. 1000 n c. 125 n d. 500 n

As a car drives with its tires rolling freely without any slippage, the type of friction acting between the tires and the road is 100) a) static friction. b) kinetic friction. c) a combination of static and kinetic friction. d) neither static nor kinetic friction, but some other type of friction. e) it is impossible to tell what type of friction acts in this situation.

Simon is writing a story about an astronaut whose spacecraft has been boarded by space pirates. the astronaut has her lucky penny in her hand behind her back as the space pirates break into the control room. she has just locked the controls so that the ship is accelerating in the direction of the control room’s ceiling. simon wants the astronaut to use the penny to hit a button on the control panel to turn off the lights and escape. the button is located a short distance behind and below the astronaut’s hands. how should simon use the theory of relativity to describe what the astronaut must do in order to hit the button?
