Asteroid Toutatis passed near Earth in 1988 at forty-five times the distance to our Moon. If it has a mass of 5.0 ✕ 1013 kg, what force (in N) did it exert on Earth at its closest approach in 1988? (Enter the magnitude.)

The place you get your hair cut has two nearly parallel mirrors 6.00 m apart. as you sit in the chair, your head is 2.00 m from the nearer mirror. looking toward this mirror, you first see your face and then, farther away, the back of your head.
