Seasons are caused by revolutions around the sun
Answer:
9:3:3:1
Explanation:
There are 420 kernels, over half of these are purple wrinkled (242/420=0.576) one fifth are purple smooth (84/420=0.2), just under one fifth are yellow wrinkled (70/420=0.167), and just over one twentieth are yellow smooth (24/420 = 0.057).
The ratio is 0.567: 0.2: 0.167: 0.057
0.567/0.057 = 9.9, so the ratio of purple wrinkled to yellow smooth is around 9:1.
0.567/0.2 = 2.835 and 0.567/0.167 = 3.39, so the ratio of purple wrinkled to purple smooth and yellow wrinkled is approx 3:1
0.2/0.057 = 3.5 and 0.167/0.057 = 2.92, so the ratio of purple smooth and yellow wrinkled to yellow smooth is approx 3:1
Therefore, the ratio is approximately 9:3:3:1.
This is a classic Mendelian ratio for a independent assortment associated with a dihybrid cross.

Newton's 3rd law of motion is the " action - reaction " law .
This 3rd law states that ;
If a body A applies a force on body B then body B also applies force on body A which is equal in magnitude and opposite in direction .
In simple terms it is stated as ;
For every action there is an equivalent opposite reaction .
This is represented as ;
![\tt{ {F}_{AB} = - {F}_{BA} }](https://tex.z-dn.net/?f=%5Ctt%7B%20%7BF%7D_%7BAB%7D%20%3D%20-%20%7BF%7D_%7BBA%7D%20%7D)
Example :-
When a birds flys in the air it pushes the air with it's wings downwards ( action ) . Similarly, the air pushes the bird upwards ( reaction ) .
