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

A. The rest have different factors that have nothing to do with college education
Answer:
no.of protons =no.of electrons = atomic number
Layers of ice and tree rings are similar in that they can both record or store data from past environmental conditions. ... Layers of ice in an ice sheet trap information that can tell about past conditions such as climate. Just like the tree rings specific sections represent a specific period of time.
brainlist would be nice i’m trying to rank up
but i hope this helped
