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: y=5x+3
Step by step explanation:
Perpendicular meaning that the product of the slope/gradient is -1 hence ...
-1/5 * x = -1
x = -1/-1/5
x = 5
The equation perpendicular to y=-1/5x-3 is y=5x-c
Now it contains the points (1,2)
x variable is 1 and y variable is 2 plug them into the line equation
2=5(1)-c
2=5-c
2-5=-c
-3=-c divide by -1
3=c
Hence the perpendicular equation is y=5x+3
Hopefully it’s correct :)
Step-by-step explanation:
Given
(-2) * ( - 4.5)
= 9
Hope it will help :)
5682 divided by 4 is 1420 remainder 2 Hope that helped Have a good day! :-)
