Explanation:
Given:
Gravity of Mars = 0.38 times the gravity at Earth
Gravity of Earth is, 
Radius of Mars (R) = 3400 km
Mass of mars (M) = ?
We know that, the acceleration due to gravity of a planet of mass 'M' and radius 'R' is given as:

Now, as per question:

Plug in 9.8 for
and solve for
. This gives,

Now, plug in this value in the above equation and solve for 'M'. This gives,

Therefore, the mass of Mars is
.

Explanation:
Answer: 1.11 x 10⁸ Pa
Explanation:
At any deep, the absolute pressure is the same for all points located at the same level, and can be expressed as follows:
p = p₀ + δ. g . h, where p₀ = atmospheric pressure = 101, 325 Pa
Replacing by the values, we get:
p= 101,325 Pa + 1025 Kg/m³ . 9.8 m/s². 11,033 m = 1.11 x 10⁸ Pa.
