Question

If you were standing at sea level measuring the air pressure, you would actually be measuring the air's _____.

friction
speed
weight
moisture

Answer 1

Weight of air per unit area is pressure due to atmosphere. So here correct answer is Weight

Step-by-step explanation:

As we know that air pressure is given by

`P = (Force)/(Area)`

now we know that force here due to air is due to the weight of the air

so here in order to calculate the weight we will have

`Weight = mg`

`Weight = \rho Ah g`

here we know that

Ah = volume of air above the point where pressure is to be calculated

now from above formula we have

`P = (\rho AH g)/(A) = \rho g h`

so here we can say that pressure is due to weight of air
