Suppose you have made the following hypothesis: the greater the height from which you drop a ball, the faster the ball will be traveling when it hits the ground because gravity has more time to speed it up.

what prediction could you make based on this hypothesis?

a. two identical balls dropped from a height of 5 m will hit the ground with different speeds.

b. two identical balls dropped from a height of 10 m will hit the ground with different speeds.

c. a ball dropped from a height of 10 m will hit the ground at a higher speed than an identical ball dropped from a height of 5 m.

d. a ball dropped from a height of 5 m will hit the ground at a higher speed than an identical ball dropped from a height of 10 m.

C. A ball dropped from a height of 10 m will hit the ground at a higher speed than an identical ball dropped from a height of 5 m.

Explanation:

The statement of the hypothesis is that " the greater the height from which you drop a ball, the faster the ball will be traveling when it hits the ground because gravity has more time to speed it up ".

The hypothesis statement is quite explicit. We can deduce that objects at a higher height above the ground will hit the ground much more faster and harder compared to those at a shorter height.

A ball at height of 10m is expected to drop with a higher speed on the ground compared to an identical ball at a height of 5m.

If the balls are at the same height, they are expected to fall with the same speed so far they are identical. Also, a ball at a shorter height will fall at a lower speed.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.
