Concept explainers
You are working for an automobile tire company. Your supervisor is studying the effects of molecules striking the inner surface of the tire due to their thermal motion. He gives you the following data from a recent experiment. The air in a tire on a parked car was measured to have a gauge pressure of Pi = 1.65 atm on a day when the temperature was T = 6.5°C. The car was then driven for a while and then measurements were taken again. The gauge pressure in the tire was then Pf = 1.95 atm and the interior volume of the tire had increased by 5.00%. (a) Your supervisor asks you to determine by what factor the rms speed of the air molecules had increased from the first measurement In the second. (b) He also hints at a proposal he is going to make to replace air in tires with argon. Will this change the factor by which the average speed of the molecules changes in the conditions described?

Please help me understand how to get there!arrow_forwardRank the six combinations of electric charges on the basis of the electric force acting on 91. Define forces pointing to the right as positive and forces pointing to the left as negative. Rank in increasing order by placing the most negative on the left and the most positive on the right.
