Hey there!
Given;
Mass of the Earth (M) = 6.0*10^24kg.
Radius of Earth (R) = 6400km = 6400*1000= 6.4*10^6.
Gravitational constant (G) = 6.67*10^-11Nm^2/kg^2.
Height from surface of Earth (h) = 350km= 3.5*10^5m
Gravity (g) = ?
We have;
Where "G" is gravitational constant, "M" is mass of earth, "g" is acceleration due to gravity, "h" height from surface of Earth.
Keep all values.
g=8.7m/s^2
Therefore,gravityfromdistance350kmabove theEarth'ssurfaceis8.7m/s^2.

Answer:
about 7500 km
Explanation:
The mass of planet Katar is 7.27×10^25 kg. The force on the kangaroo is given by ...
F = GmM/r^2
Solving for r, we have ...
r = √(GmM/F) = √(6.67×10^-11 × 78.2 × 7.27×10^25 / 6742) ≈ √(5.62×10^13)
This is in meters, so the radius in km is about ...
r ≈ 7500 km
B. absolute zero.
C. evaporation.
D. condensation.
By definition we have to:
In physics, condensation is a change of state by which a substance passes from a gaseous state to a liquid state.
For example, in a refrigeration cycle, the refrigerant leaves the compressor in the gaseous state, from here, it enters the condenser, a state change called condensation occurs and the refrigerant leaves in liquid form. This process is useful in air conditioners.
Answer:
The process in which a substance changes from a gaseous state to the liquid state is:
D. condensation.
