Answer:
The answer to the question is as follows
The acceleration due to gravity for low for orbit is 9.231 m/s²
Explanation:
The gravitational force is given as
Where = Gravitational force
G = Gravitational constant = 6.67×10⁻¹¹
m₁ = mEarth = mass of Earth = 6×10²⁴ kg
m₂ = The other mass which is acted upon by and = 1 kg
rEarth = The distance between the two masses = 6.40 x 10⁶ m
therefore at a height of 400 km above the erth we have
r = 400 + rEarth = 400 + 6.40 x 10⁶ m = 6.80 x 10⁶ m
and =
= 9.231 N
Therefore the acceleration due to gravity = /mass
9.231/1 or 9.231 m/s²
Therefore the acceleration due to gravity at 400 kn above the Earth's surface is 9.231 m/s²
Answer:
The distance in kilometers is 4012 × km.
Explanation:
We know that the conversion of 1 millimeters is equal to meter. And then the conversion of 1 meter is equal to
km. Then the conversion of 1 millimeter to km will be
1 mm = m
1 m = km
So, 1 mm = ×
km =
km.
As here the the distance is 4012 mm, then the distance in km will be
4012 mm = 4012 × km.
So the distance is 4012 × km.
