Gravity on Mars is 1/3 of that on earth. If Mars atmosphere is only 2 km thick, what is atmospheric pressure on Mars?
To calculate the atmospheric pressure on Mars, we need to know the density of its atmosphere at the surface. However, without that information, we can make an assumption to estimate the pressure.
First, we know that the gravity on Mars is 1/3 of that on Earth. This means that the force exerted on a given mass on Mars would be 1/3 of the force exerted on the same mass on Earth.
Since pressure is defined as force per unit area, we can infer that the atmospheric pressure on Mars would be approximately 1/3 of the atmospheric pressure on Earth. On Earth, the standard atmospheric pressure at sea level is about 101.325 kilopascals (kPa).
Therefore, we can estimate the atmospheric pressure on Mars to be around 1/3 of 101.325 kPa, which is approximately 33.775 kPa.
Please note that this is a rough estimation, as the density of the Martian atmosphere can vary at different heights and locations.
