A 90kg person stands 0.5m from a 60kg person sitting on a bench nearby. What is the magnitude of the gravitational force that the 90kg person exerts on the 60kg person?

The answer is 1.44*10^-6N. I need to know which formula to use.

One piece is then cut into four equal cubes and the other into 32 equal cubes.How many cubes have atleast one blue face?

I work for Wikipedia and I have a question: I've tried and tried to find information on the extinct mammal order "Macraucheniidae", but have, so far, found very little information. In all honesty, I expect that few will even know what I'm talking about.
But to those of you who do, kindly share your knowledge.

I take poppers (iso-butyl nitrite) and, admittedley, have not felt any deleterious effects. I do realize that this is no indication that there have been no deleterious effects and was wondering if there is any scientific evidence for any.

Thank you

Graph each system of equations and state its solution. Then state whether the system is consistent and independent, consistent and dependent, or inconsistent.

x + y = 6
x - y = -2


x + 1 = y
2x - 2y = 8


2x + 4 = 8
x + 2y = 4


x + y = 1
3x + 5y = 7

Thank you
