Answer:
Explanation:
The value of acceleration due to gravity of mars is same as that the value of acceleration due to gravity of Mercury.
The value of acceleration due to gravity of a planet depends on its mass and the radius.
The formula for the acceleration due to gravity is given by

Where, M be the mass of the planet, R be the radius of the planet.
As according to the question, the value of acceleration due to gravity for Mercury is same as that of Mars.


As teh radius of Mercury is small, and acceleration due to gravity is same, it is possible because the mass of Mercury is more than the mass of Mars.
Answer:
The Troposphere is the lowermost portion of Earth’s atmosphere. It is the densest layer of the atmosphere and contains approximately 75 percent of the mass of the atmosphere and almost all the water vapor and aerosol. The troposphere extends from the Earth’s surface up to the tropopause where the stratosphere begins.
Explanation:
So this is dealing with the conservation of energy. So you set kinetic energy equal to potential energy, so it looks like this:
1/2mv^2=mgh. The m's cancel out, so it is 1/2v^2=gh.
To find out what the height h is, divide g on both sides, so...
h=0.5v^2/g. v=22m/s, g=9.81m/s^2, so h=(0.5)(22^2)/(9.81)=24.67m
