1: C because force s is pushing 250n to the left and force t is pushing 250n to the right so they both cancel each other out
2: A because forces q and r both push 200n to the left
3: A a baseball bat hits a ball because the force of the baseball bat is going into the ball which sends the ball through the air.
4: B because the gravitational force is deceasing as the distance stays the same.
5: the grvitational between the two objects decreases as the distance between the two objects increases.
6: A the static friction on the cart is -150n because since the the cart is not moving the forces would have to be cancleing each other out.
hope this helps
