Two students, student 1 and student 2, did the same experiment simultaneously to measure parallax. student 2's eyes are farther apart than student 1's eyes. the steps of the experiment are listed below. 1. hold the thumb out at arm's length. 2. look at the thumb and alternately open and close each eye. 3. estimate the distance by which the thumb appears to move with respect to background objects. based on the experiment, what would the students most likely conclude about the parallax method of measurement of star distances? a. both the parallax measurements should be taken at the same time b. parallax shift remains the same when measured by different instruments c. the shift in parallax while measuring star distances depends on the distance between the two points of observation d. parallax would be most effective in measuring distances to stars which are more than a billion light years away from earth

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
