Answer:
E. downward and constant
Explanation:
Freefall is a special case of motion with constant acceleration because the acceleration due to gravity is always constant and downward. This is true even when an object is thrown upward or has zero velocity.
For example, when a ball is thrown up in the air, the ball's velocity is initially upward. Since gravity pulls the object toward the earth with a constant acceleration ggg, the magnitude of velocity decreases as the ball approaches maximum height. At the highest point in its trajectory, the ball has zero velocity, and the magnitude of velocity increases again as the ball falls back toward the earth.
Answer: Explanation:
Carbonated drinks are mixtures of water, sugar, flavorings, and dissolved carbon dioxide gas. They are homogeneous because the ingredients are mixed together to form a consistent liquid.
Answer:
built in potential Vbi = +0.5V
barrier height = 0.139 V

Explanation:
i took the test on engenuity
The average speed of the runner is 8.7m/s.
Therefore, Option C) 8.7m/s is the correct answer.
Given the data in the question;
Distance covered; 
Time taken; 
Average speed; 
Speed is the rate at which an object covers a certain distance. It is expressed as:
Where s is speed, d is distance and t is time taken.
We substitute our given distance into the equation
The average speed of the runner is 8.7m/s
Therefore, Option C) 8.7m/s is the correct answer.
