Answer:
The deceleration of the plane is 0.25 m/
.
Explanation:
Deceleration is the converse of acceleration.
From first law of motion, we have;
v = u + at
where: v is the final velocity, u is the initial velocity, a is the acceleration and t is the time taken.
Thus,
v = 50 m/s
u = 80 m/s
t = 120 s
50 = 80 + 120a
50 - 80 = 120a
-30 = 120a
a = ![\frac{-30}{120}](https://tex.z-dn.net/?f=%5Cfrac%7B-30%7D%7B120%7D)
= -0.25
a = -0.25 m/![s^{2}](https://tex.z-dn.net/?f=s%5E%7B2%7D)
The deceleration of the plane is 0.25 m/
.

Answer:
D. Codominance
Explanation:
Codominance is when both alleles are expressed with the resulting phenotype being the intermediate of the two. For example, red and white phenotypes results to a pink one.

Answer: The nervous system has two main parts:
The central nervous system is made up of the brain and spinal cord.
The peripheral nervous system is made up of nerves that branch off from the spinal cord and extend to all parts of the body.
