Four 6.5 kg spheres are located at the corners of a square of side 0.78 m. Calculate the magnitude and direction of the gravitational force on one sphere due to the other three.

I have tried using the formula with Cavendish's constat it didn't work. I did Gm1m2/r^2 which i got my answer as 9.26E-9 which was WRONG. There is an identical problem in my book with 7.5 kg mass and .6 length of a square side. I did that one the same way and got the right answer in the back. 2.0E-8, could someone tell me how to do my problem correctly? Show steps so i can understand it.

In physical terms, what exactly IS a smell or odor? OK, if it's a fart, I know that you're smelling gases such as methane and sulfur dioxide. But what about wet leaves or fried chicken or cookies baking? When you catch the smell of it, what exactly is being sensed by your olfactory nerve and taste buds? Is an odor composed of invisible particles of the substance or something like that?

If I understand correctly, in order to be blonde, a person must have two recessive blonde genes. If that person had a child with another person who was also blonde, how is it possible for them to have a child with brown hair when there was no dominant gene passed down? Is it impossible? Will light-haired parents always have light-haired children?
