Magnitude of the maximum gravitational force problem
A bowling ball (mass=7.2kg, radius=0.11m) and a billiard ball (mass=0.38kg, radius=0.028m) may each be treated as uniform spheres. What is the magnitude of the maximum gravitational force that each can exert on the other?

Do the sample data provide sufficient evidence to conclude that gender and opinion are related in the population? Use ?=.05. (Need a walkthrough for how to do this in Minitab: A > B > C > D works)
Assuming there are no energy losses due to air resistance and therefore that the acceleration is constant. Plot a graph of the kinetic energy of the mass against distance.
Suppose you conduct a significance test and decide to Fail The reject the null hypothesis H0 at the alpha =.05 level. If you conduct the same test on the same data but instead use the alpha =.01 level, what decision would you make? Circle your ans
A S2- ion-selective electrode gave an electrodepotential of E = -0.254 V when immersed in a 7.76 10-2 M standard K2S solution. Assuming thatthe electrode behaved ideally, calculate the molarity of an unknownS2- solution which gave a potential of E
A point charge +6q is located at the origin, and a point charge -3q is located on the x-axis at D = 0.447 m. At what location on the x-axis will a third charge, q0, experience no net force from the other two charges?
