Question

The atmospheric pressure at the surface of Venus is 91 times the pressure at sea level on Earth. With approximately how much total force would Venus’s atmosphere push on an average human being at sea level? Assume that the surface area of an average human being is 1.8 m2.

Answer 1

The total force Venus's atmosphere would exert on an average human at the surface of Venus, with a surface area of 1.8 m2, would be approximately 16.674 × 106 Newtons.

Step-by-step explanation:

The atmospheric pressure on Venus is approximately 92 times that of Earth. If the atmospheric pressure at Earth's surface is 1.01 × 105 N/m2, then the atmospheric pressure on Venus can be estimated to be 92 × 1.01 × 105 N/m2. Given that the surface area of an average human is around 1.8 m2, we can calculate the total force exerted on a human body by Venus's atmosphere.

To find the total force, we multiply the atmospheric pressure by the surface area:

Force = Pressure × Area = (92 × 1.01 × 105 N/m2) × 1.8 m2 = 1.6674 × 107 N

Therefore, the total force exerted on an average human at the surface of Venus would be approximately 16.674 × 106 Newtons, or 16.674 MegaNewtons (MN).

Answer 2

17×10⁶ N

Step-by-step explanation:

1 atm on Earth is 101325 Pa.

So on Venus, the atmospheric pressure is:

91 × 101325 Pa = 9220575 Pa

The force on an average human being would be:

F = PA

F = 9220575 Pa × 1.8 m²

F = 16597035 N

Rounded to two significant figures, the force would be 17×10⁶ N, or 17 MN.
