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.

                    Pressure, P=\frac{Thrust}{Area}=\frac{F}{A}

  • A particular mass of air is contained in a column that rises from the ocean to the top of the atmosphere. Then,

                   P=P_a=1.013*10^5 pascal

Pa is the atmospheric pressure at the sea level.

  • By combining both the equations, we get the weight of air,

                                       \frac{F}{A}=P_a

              F=W=P_a*A=1.013*10^5*1=101300N

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.

Electromagnetic waves can behave like particles
Ilya [14]
Yes they can.  Uh-huh.  Indubitably.  That's right, Vanessa.  It's true.

A better way to say it might be:

         Electromagnetic radiation can behave like waves AND like particles.
