I believe the answer is : A - Evolution
Good luck!
To find the circumference we must work backwards from the area to find the radius of the circle.
Area = pi x radius squared
4 x pi = pi x radius squared
4 = radius squared
2 = radius
Now that we have the radius, we can plug it into our formula for circumference.
Circumference = pi x diameter (or 2 x radius)
Circumference = pi x 4
Circumference = 4
Answer:
B) Air Resistance
Explanation:
A reaction force is the opposite of an action force, so what is opposing gravity? Momentum certainly isn't in this instance of the apple falling. Thermal velocity isn't, and anti gravity is a hypothetical phenomenon.
