The first thing you should know is that the gravitational force is:
F = GMm / r ^ 2
Then, by definition, the force is equal to
F = m * a = mv ^ 2 / r
We match both expressions:
GMm / r ^ 2 = mv ^ 2 / r
Let's clear the speed:
v = (GM / r) ^ (1/2)
On the other hand:
r = R + h
Substituting:
v = (GM / (R + h)) ^ (1/2)
Where,
G = 6.67x10 ^ -11 n · m2 / kg2
M = 5.98x10 ^ 24 kg
R = 6.38x10 ^ 6 m
h = 6.16 x 10 ^ 8 m
Substituting the values:
v = ((6.67 * 10 ^ -11) * (5.98 * 10 ^ 24) / ((6.38 * 10 ^ 6) + (6.16 * 10 ^ 8))) ^ (1/2)
v = 800m / s

Answer:
8
Step-by-step explanation:
Fourmla:
a^2+b^2=c^2
7^2=49
3^2=9
49+9=58
square root of 58 is about 8.

The reason why partitioning and fractioning are different is because; The ratio given is part to part. The total number of parts in the whole is 1 + 3 = 4.
<h3>Why is partitioning different from fractioning?</h3>
It follows from the task content that a close analysis of the statement of ratios; 1:3 implies that the whole is divided into four parts; 1+3 = 4.
On the contrary, one-third simply means 1 out of 3 equal parts of the line.
