The magnitude of the force of the elevator floor on the person is; 807.13 N
<h3>What is the Magnitude of force? </h3>
We are given;
Weight; W = 0.7 KN
Acceleration; a = 1.5 m/s²
There are only two forces acting on the person: which are his weight W (downward) and the normal force N of the floor against the body (upward). Thus the equilibrium equation here is;
N - W = F
N - W = ma
Here, m is the mass of body, and its value is calculated as;
W = mg
0.7 = 9.81m
m = 0.7/9.81
m = 71.42 kg
Thus;
N - 0.7 = 71.42 * 1.5
N = 0.7 + (71.42 * 1.5)
N = 807.13 N

The example which best illustrates the role of the legislative branch in national security is: A. united states meets with other leaders to negotiate a trade treaty.
<h3>What is the
legislative branch?</h3>
Legislative branch can be defined as one of the three branch (arm) of government that is saddled with the responsibility of creating and enacting laws in a particular country.
In the area of national security, an example which best illustrates the role of the legislative branch is the United States of America meeting with other world leaders to negotiate a trade treaty, so as to foster the buying and selling of goods among them.

It should be noted that the angular momentum remain constant and kinetic energy of the skater increases.
<h3>What is Angular momentum?</h3>
Angular momentum can be regarded as the property of any rotating object given by moment of inertia times angular velocity, since No net torque is done on the object, then angular momentum is constant.
Kinetic Energy which is also the energy of motion in the Ice skater will increase since their is a pull.

A central character whose trustworthiness the reader is invited to doubt.
For better understanding, let us explain why the doubt
- A central character in a story is one story is one who the people, audience or readers base their focus upon. The reader's state of mine be it emotional attachment is often yielded towards the story.
- When the main character has lost its credibility and cannot be trusted no more, it will invite a lot of doubt in the reader's mind.
from the above, we can therefore say that the answer A central character whose trustworthiness the reader is invited to doubt is correct
