Final answer:
The average force exerted by the atmosphere at sea level is approximately 1 kg/cm².
Step-by-step explanation:
The average force exerted by the atmosphere at sea level is approximately 1 kg/cm².
Atmospheric pressure at sea level is about 1.01 × 105 N/m², which is equivalent to 1 atm. This pressure results in a weight of 1.01 × 105 N on 1 m² of the Earth's surface.
Since 1 cm is equal to 0.01 m, the force exerted on 1 cm² of the Earth's surface is approximately 1 kg/cm².
