Problem 2: The force between a positively charged foam cup and a positively charged metal sphere is 5.2 x 10-4 newtons. The charge on the cup is 7.2 x 10-6 coulombs, and the charge on the metal sphere is 6.8 x
10-6 coulombs. What is the distance between the two objects? (k = 9.0 x 10° newtonmeters 2 coulombs?)
Part C: Modify the force equation to solve for the distance, r. Do not enter any numbers. Just express r as an equality
in terms of the other variables. Use your keyboard and the keypad to enter your answer. Then click Done.

Mercury poisoning is dangerous overload of mercury within the body. a major source of mercury within the body, a major source of mercury poisoning is consuming fish that contain mercury. certain fish are more prone to having higher levels of mercury than others. the pie chart shows the distribution of four breeds of fish at a hatchery. the hatchery has approximately 6,000 fish. a biologist from the centers for disease control and prevention randomly test 5% of each breed of fish for mercury content. her findings are shown in the following table. based on the biologist's findings, if a single salmon is randomly selected from those that were tested, what is the probability that this particular fish would have a dangerous mercury level? a) 0.001 b) 0.004 c) 0.02 d) 0.08
