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

people need to watch out for their environment by not smoking, not littering, and such bad things like that.
One of the examples from the text that can be regarded as clear, logical and sincere is:
- The speaker said, this nation would endure, revive and prosper.
He goes to say that they only thing that they had to fear was fear itself. He said this to show that fear may keep them from advancing when they should have done so.
The president used the words such as revive to show that the nation was still capable of enduring and coming out of the dark times that they were in.
From these words we can see that the president was logical and also sincere in what they were passing through and how they were to overcome it.
