How is it true that that if earth pulls on a grapefruit with a force of 1 newton the grapefruit also exerts a force of 1 newton on Earth?

It is true. Such forces always come in pairs. (This is related to Conservation of Momentum.) Of course, the effect of such a force on the Earth - the amount Earth accelerates, if you release the grapefruit - will be much less than the effect on the grapefruit (by Newton's Second Law).

What Force That Gravity exerts on a mass?
Gravity is approximately a 9.8 newton force towards the center of the earth.
How does the size of the force exerted by earth's gravity on a car compare with the size of the car exerts on earth?
The magnitude of the force is exactly the same (Newton's Third Law).
1Newton in kgs?
A Newton (or a Kilonewton) is a measure of FORCE, not of weight. On Earth's surface, a mass of 1 kg exerts a force of approximately 9.8 N [down]
When a ball is dropped it is easy to see that earth exerts a force on it Why cant you tell that the ball exerts a force on earth?
it moves
When you drop a 0.40 Kg apple earth exerts a force on it that accelerates it 9.8 ms2 toward the earth's surface according to Newton's third law the apple must exert an equal and opposite force on?
I believe earth eats the apple. that's it.

How much force does a person in outer space exert on earth if the earth exerts 850 N on the weightless person?
The person in space exerts a force of 850 N on the earth. The fact that the person is weightless has no bearing on this question. Ever since Newton enunciated his three laws of motion we have known that action and reaction are equal and opposite. If the earth pulls him with 850 N, then he pulls the earth with 850 n.
Does Earth exert gravity?
Anything that has mass exerts a gravitational field, so yes, earth exerts one.

Who has more gravity the moon are the earth?
The earth exerts a stronger gravitational force.
Earth exerts a force on an object equal to the object's weight. the object exerts a force on Earth?
Of exactly the same magnitude but in the opposite direction.
When you drop a 0.40 Kg apple earth exerts a force on it that accelerates it 9.8 ms2 toward the earth's surface according to Newton's third law the apple must exert an equal and opposite force on?
I believe earth eats the apple. that's it.
How does the size of the force exerted by Earths gravity on a car compare with the force the car exerts on Earth?
The magnitude of the force is exactly the same (Newton's Third Law).
