Question

if the area of the head were 15cmx15cm .how much force will air exert on my head

Answer 1

Explanation:

Given, Area of head=15cm×15cm

=>15/100meters×15/100meters

=>225/10⁴ =225×10⁻⁴

1 atm=10⁵ Pascals

We know pressure formulae,

Pressure=Force/ Area

10⁵ pa=F/225×10⁻⁴ m square

F= 10⁵Pa ×225×10⁻⁴ m square

10⁵N/ m²×225×10⁻⁴ m²

m² in numerator and the denominator will be cancelled.

=>225×10 N

F=2250 N
