In the "uniform circular motion" lab a group of students are to spin a 500 gram mass with a constant centripetal force of 5.88 n at a radius of 17.0 cm, they are to measure the period and then increase the radius and repeat the measurement for 5 different radii. if they plot v2 vs. r what is the expected slope of the linear line that should result from their plotted data.

The air in an automobile tire with a volume of 2.60 ft3 is at 70°f and 21 psig. determine the amount of air that must be added to raise the pressure to the recommended value of 30 psig. assume the atmospheric pressure to be 14.6 psia and the temperature and the volume to remain constant. the gas constant of air is ru = 53.34ft⋅lbflbm⋅r(1 psia144 lbf/ft2) = 0.3704 psia⋅ft3lbm⋅r the amount of air that must be added to raise the pressure is lbm

The ph is the a.independent variable b.the dependent variable c.control group
