From sea level to the top of the atmosphere, a column of air with a 1-m2 cross section weighs 101,000 N.
To find the answer we have to know about the pressure.
<h3>
What is Pressure?</h3>
- The pressure at a point on a surface is the thrust acting per unit area around that point.
- A particular mass of air is contained in a column that rises from the ocean to the top of the atmosphere. Then,
Pa is the atmospheric pressure at the sea level.
- By combining both the equations, we get the weight of air,
Thus, we can conclude that, the weight of air in a column 1-m2 in cross section that extends from sea level to the top of the atmosphere is 101300N.

Explanation:
Answer:
2160.26 N.
Explanation:
From the question,
The total energy of the woman = work done by the water.
mg(h+d) = F'×d.......................... Equation 1
m = mass of the the woman, g= acceleration due to gravity, h = height of the platform, d = depth of water reached by the woman, F'= Resistance force exerted on her by the water.
make F' the subject of the equation
F' = mg(h+d)/d............................ Equation 2
Given: m = 65.0 kg, g = 9.8 m/s², h = 11 m, d = 4.6 m.
Substitute into equation 2
F' = 65(9.8)(11+4.6)/4.6
F' = 9937.2/4.6
F' = 2160.26 N.
Voltage, resistance and current are the three components that must be present for a circuit to exist. A circuit will not be able to function without these three components. Voltage is the main electrical source that is present in a circuit. :)
