Answer:
3149.181 N
Explanation:
the force exerted by the atmosphere can be calculated as
F = PA
Where P is the atmospheric pressure and A is the area of the sheet of paper.
The atmospheric pressure is P = 101325 Pa
And the area is equal to
A = Length x Width
A = 0.148 m x 0.210 m
A = 0.03108 m²
Because 14.8 cm = 0.148 m and 21.0 cm = 0.210 m
Now, we can calculate the force as
F = (101325 Pa)(0.03108 m²)
F = 3149.181 N
So, the force exerted is 3149.181 N
