Air pressure is measured in pascals. For a professional American football game, the ball should be inflated to about 90,000 pascals. Scientists studied the effects of air temperature on the pressure inside American footballs by taking these steps: 1. Prepare 100 footballs. 2. Measure each football's air pressure. 3. Divide footballs into 10 groups. 4. Place the groups in different lockers cooled to different air temperatures. 5. After 12 hours, remove the footballs from lockers. 6. Measure each football’s pressure again. 7. Compare the new pressures to the starting pressures. What two terms best describe the variable "air pressure inside the football" in this experiment?

the one that starts with d and the one that starts with q

Explanation:

The Answer is d

Explanation:

like many students at university, you may be unhappy about the results you attain in exams. you may feel that even with all you are doing there must be something more -- or different-- you could be doing to get better grades. we have all at some time or other heard of that student who only studies a couple of hours for final exams and scores a's every time. we stand in awe of those who seem to breeze through without undue effort and seem to need very little in the way of studying to nail an exam. the reasons for success, in what i think are the vast majority of cases, are less esoteric than many students think: successful students consistently apply a series of productive strategies with view to attaining clearly identified learning and grade goals throughout the academic term.
