Answer:
2.87m
Explanation:
Using the law of gravitation to solve this question
F = GMm/r²
G is the gravitational constant
M and m are the masses
r is the distance between the masses
Substitute the given values
G = 6.67×10^-11 m³/kgs²
M =8.8 x 10^6 kg
m = 5.6 x 10^5 kg
F =440N
400 = 6.67×10^-11×8.8 x 10^6 ×5.6 x 10^5/r²
400r² = 328.698×10
400r² = 3286.98
r² = 3286.98/400
r² = 8.21745
r = √8.21745
r = 2.87m
Hence the distance of separation is 2.87m

The total distance you would have covered is equivalent to going around the earth 22 times.
<h3>
Total distance traveled</h3>
The total distance traveled at a given speed and time of motion is calculated as follows;
Distance = speed x time

<h3>Distance round the Earth</h3>
The distance round the earth or circumference of the earth of the earth has been given as 25,000 miles
<h3>Number of times round the earth</h3>

Thus, the total distance you would have covered is equivalent to going around the earth 22 times.

Answer:
6
Explanation:
The rate of change in this scenario corresponds to the number of inches that Ree grows every year. Basically, Ree's height can be written as a linear equation as follows:

where
x is the number of years after the first birthday
y is the height in inches
q = 27 is the height of Ree on her first birthday
m = 6 is the inches gained by Ree at each birthday
So the equation can also be rewritten as
y = 6x + 27
Answer & Explanation:
Formula
Acceleration = change in velocity / time taken
Acceleration = 5 / 300
Acceleration = 0.016
hence final answer = 0 m / s^2
