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

With 3D printing, in society, most goods will be designed on computers and “manufactured” in the homes of consumers, which over time will reduce both the costs and environmental impacts of transportation.
<h3>What is conventional theory of the formation of the galaxy ?</h3>
The conventional theory of the formation of the galaxy can be regarded as one that stressed that the formation of milky way was done relatively short time some million years ago.
And this was when spherical cloud of gas collapsed as a result of pressure the particular gravity which was surrounded by a halo.
Therefore, formation of the galaxy was recorded to occur roughly 12 to 13 billion years ago .
