Final answer:
The force exerted by Mars's atmospheric pressure is about 144 times smaller than that exerted by Earth's atmosphere at sea level.
Step-by-step explanation:
The student has asked how many times smaller the force exerted on your body by the atmospheric pressure on the surface of Mars would be, compared to the force exerted by Earth's atmosphere at sea level. To answer this, we compare the atmospheric pressure on Mars, which is about 700.0 Pa (0.007 bar) to the atmospheric pressure at Earth's sea level, which is about 1.01×105 Pa (1 atm or 1.013 bars).
The ratio of the Martian pressure to the Earth pressure is 700.0 Pa / 1.01×105 Pa = 0.00693 (rounded to five significant figures). This means the force exerted on your body by Mars's atmosphere is approximately 1/144 (0.00693 is roughly 1/144 when converted to a fraction) of the force exerted by Earth's atmosphere at sea level.
Therefore, the force exerted on your body by the atmospheric pressure on Mars is about 144 times smaller than that on Earth at sea level.
