Water gets to the leaves in the tops of the tallest trees by something called the cohesion-tension theory. Water has two very unique properties called adhesion and cohesion. Cohesion is the tendency of water molecules to stick together with one another. The water sticks together, leaving no room for air, strengthening the "force" of the water going up the tree. The water also sticks to the sides of the xylem inside the tree. In addition to these properties, there are also the factors of negative and positive water potential. For more information, look up more details of the cohesion-tension theory.
the answer is (a) molecules

Find the final velocity of the rock first:
The total energy of the rock at rest:

The total energy of the rock after 7m:

Energy must be conserved:

Momentum must be conserved also.
Momentum with the ball at rest:

The total momentum is zero with the ball at rest and must remain zero.
Momentum with the ball at 7m:

Solving for the earth's velocity v₂:
Answer:
Decreases
Explanation:
The potential energy of an object is how much energy that object COULD release. When in reference to falling objects, the formula for the potential energy of an object is mgh, where m is the mass in kilograms, g is the acceleration, and h is the height. This is why, as the height of an object decreases, so does its potential energy. Hope this helps!
