The answer is <u>"d. increased temperature".</u>
At the point when corals are stressed by changes in conditions, for example, temperature, light, or supplements, they remove the symbiotic algae living in their tissues, making them turn totally white. Hotter water temperatures can result in coral bleaching. At the point when water is too warm, corals will oust the algae living in their tissues, making the coral turn totally white. This is known as coral bleaching.
When a coral blanches, it isn't dead. Corals can endure a bleaching occasion, yet they are under more pressure and are liable to mortality.
The average velocity of an object is given by:
Average velocity = total displacement / total time
First, we calculate the time taken to reach the maximum height of the ball. This occurs when the final velocity is 0.
Vf = Vi + at
0 = 19.6 - 9.81 * t
t = 2 seconds
The total trip will be of 4 seconds (2 seconds up, 2 seconds down)
The total displacement is given by:
s = ut + 1/2 * at²
s = 19.6 * 2 - 0.5 * 9.81 * 2²
s = 19.6 meters
This is the distance maximum height, so the total height is
19.6 * 2 = 39.2 meters
Average velocity = 39.2 / 4
Average velocity = 9.8 m/s
<span>This is best understood with Newtons Third Law of Motion: for every action there is an equal and opposite reaction. That should allow you to see the answer.</span>
This doesnt make sense. 2g<span>Δym is simply an equation. </span>
