Answer:
its most definitely c. trust me
Explanation:
Answer:
9.6
Explanation:
to convert km to miles multiply by 1.609
The strength of the gravitational field is given by:

where
G is the gravitational constant
M is the Earth's mass
r is the distance measured from the centre of the planet.
In our problem, we are located at 300 km above the surface. Since the Earth radius is R=6370 km, the distance from the Earth's center is:

And now we can use the previous equation to calculate the field strength at that altitude:

And we can see this value is a bit less than the gravitational strength at the surface, which is

.
It would take about 2 thirds of a second or .66666666 repeating of a second. please give brainliest?
