the answer is d it reflects all the wavelengths of visible light.
That's true.
Netwon's second law states that the resultant of the forces F acting on a body is equal to the product between its mass m and its acceleration a:

This means that if the net force acting on an object is different from zero (term on the left), than the acceleration of the object (term on the right) must be different from zero as well, and therefore the body is accelerating.
In particular, both F and a in the equation are vectors: this means that if the acceleration is positive, F and a have the same direction. In this problem, the acceleration is positive (because the object is speeding up), therefore the force and the acceleration have same direction.

Explanation:
Step 1:
We know that the expression for potential energy is
PE = mgh
where, m =Mass
g = Acceleration due to gravity
h Height
Step 2:
Here m = ?
PE = 108486
h = 30 m
g = 9.8 ms⁻²
108486 = 
The similarity between tornadoes and hurricanes is they both contain strong rotating winds that can cause damage. The parent storm clouds are much larger for a hurricane than a tornado, a tornadoes "life" is a lot shorter than a hurricane, etc.
C. Farmers and gardeners should use other methods..........
