Experiment:
Car 1 will roll down the ramp and exert a force on car 2. The force experienced by car 2 is measured indirectly using (the distance it travels? or its speed?)
. If the force increases, car 2 will travel (?slower ? Farther?)
. The independent variable, or whatâs being manipulated in the experiment, is (? the starting height of car 1 or The type of bumper attached to car ?)
. The dependent variable, or whatâs responding, is (?The distance car 2 travels or the speed of car 1?)
. The height and starting position on the ramp are constants in this experiment.

Assume that a person skiing high in the mountains at an altitude of h = 15100 ft takes in the same volume of air with each breath as she does while walking at sea level. determine the ratio of the mass of oxygen inhaled for each breath at this high altitude compared to that at sea level. assume that the air composition (i.e. % of air that is oxygen) is the same at sea level as it is at 15100 ft.

Consider a 1000 w iron whose base plate is made of 0.5 cm thick aluminum alloy 2024-t6 (Ď = 2770 kg/m3 and cp = 875 j/kg°c). the base plate has a surface area of 0.03 m2. initially, the iron is in thermal equilibrium with the ambient air at 22°c. assuming 90% of the heat generated in the resistance wires is transferred to the plate, determine the minimum time needed for the plate temperature to reach 200°c.
