Help with the access part
Let's design a physics experiment to make a grape hover in midar. We can insert a point charge of q=15 into the grape, and then paint a uniform charge onto the floor. Suppose our grape has a mass of m仁5 g, what surface charge density must we paint onto the floor? PAPER SOLUTION Solve the problem on paper first, including all four IDEA steps. You will become a better physicist that way! Have you finished...

4. Question 5.7. Johnson and Leone (Statistics and Experimental Design in Engineering and the Physical Sciences, Wiley, 1977) describe an experiment to investigate warping of copper plates. The two factors studied were the temperature and the copper content of the plates. The response variable was a measure of the amount of warping. The data were as follows: Copper Content (%) Temperature (C)40 100 17, 20 16,2 24. 22 28, 27 12.9 18, 13...
