Question

if the area of my head were 10 cm 10 cm how much weight of air would i be carrying on my head​

Answer 1

Answer:100N

Explanation:

pressure(P) = force (F) ÷ area in contact(a)

hence ,

F = p × a

atmospheric pressure of earth is approximately 100000N/m²

hence ,

p = 100000N

a = 10 cm² = 10/( 100 × 100 ) = 0.001m³ ( converted the unit since si unit of area is m³)

hence :

F = (100000 × 0.001)N

  = 100N (ANS)
