Explanation:
The tangential velocity of the ball is 0.63 m/s.
<h3>
What is tangential speed?</h3>
Tangential speed is the linear component of the speed of any object moving along a circular path.
v = ωr
where;
- v is the tangential speed
- ω is the angular speed (rad/s)
- r is the radius of the circle
At a given radius of the circle = 0.3 m
Let the number of revolution per min = 20 rev/min

v = ωr
v = 2.1 x 0.3
v = 0.63 m/s
Thus, the tangential velocity of the ball is 0.63 m/s.

The carbon cycle refers to the processes by which carbon in the biosphere is recycled. Photosynthesis sucks carbon dioxide out of the atmosphere, while cellular respiration releases it into the environment. Photosynthesis is the process by which solar energy reaches a plant and is converted into glucose.
<u>How photosynthesis and cellular respiration are similar:</u>
<em>Photosynthesis</em> is a method by which plants and other organisms transform light energy into chemical energy, which is then released to fuel the organism's metabolic activities through<em> </em><em>cellular respiration.</em>
