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.

Explanation:
The height of the tomato in air after 2.1 seconds is 78.31 m.
<h3 /><h3>What is height?</h3>
Height can be defined as vertical distance either between the top and bottom of something or between a base and something above it.
To calculate the height of the tomato after 2.1 seconds, we use the formula below.
Formula:
- H = ut+gt²/2............. Equation 1
Where:
- H = Height of the tomato
- u = Initial velocity = 27 m/s
- g = Acceleration due to gravity = Constant = 9.8 m/s²
- t = 2.1 seconds
Substitute these values into equation 1
- H = (27×2.1)+(9.8×2.1²)/2
- H = 56.7+21.609
- H = 78.31 m
Hence, the height of the tomato after 2.1 seconds is 78.31 m.

Answer:
Explanation:
An object’s mass will remain constant throughout the universe, but its WEIGHT can change from planet to planet.
If you increase the mass of a planet, what happens to its gravity?
If the radius does not change, Then its gravity increases.
If the gravity on a planet decreases, what happens to the weight of an object on that planet? Weight decreases.
