In a lesson about the behavior of gases, genaris and her classmates learn that the volume of a gas is affected by its temperature. they formulated a hypothesis: if the temperature of a gas increases, the volume of the gas will increase because the increased temperature will increase the kinetic energy of the particles, which will then result in the expansion of the gas. the results of their experiment supported the hypothesis. they wanted to know if there were other factors that affect the volume of a gas. what would genaris and her classmates most likely do to test this idea? they would formulate a new hypothesis with the same independent variable but a different dependent variable as the original hypothesis. they would formulate a new hypothesis with a different independent and dependent variable as the original hypothesis. they would formulate a new hypothesis with the same dependent variable but a different independent variable as the original hypothesis. they would formulate a new hypothesis that has the independent and dependent variables of the original hypothesis switched.

Jason and mia are both running in a race. as they approach the finish line, you being the physicist that you are decide to time how long it takes them to reach the end of the race. when you start your stop watch (you can take this as time t = 0 s) you notice that mia is an unknown distance d ahead of jason and both are moving with the same initial velocity v_0. you also notice that jason is accelerating at a constant rate of a_j, while mia is deaccelerating at a constant rate of -a_m. jason and mia meet each other for the first time at time t = t_1. at this time (t = t_1) jason's velocity is two times that of mia's velocity, meaning v_j (t_1) = 2v_m (t_1). a) draw the position vs. time graph describing mia's and jason's motion from time t = 0 to time t = t_1. clearly label your axes and initial conditions on your graph. b) draw the velocity vs. time graph describing mia and jason's motion from time t = 0s to time t = t_1. clearly label your axes and initial conditions on your graph. c) how long from when the stop watch was started at t = 0s did it take mia and jason to meet? express your answer in terms of know quantities v_0, a_m, and a_j. d) when the stop watch started at time t = 0s, how far apart, d, were mia and jason? express your answer in terms of know quantities v_0, a_m, and a_j.
