Question

Calculate the atmospheric pressure acting on the head of a person if the area of his head is 10 cm X 10 cm and the amount of atmospheric pressure present over his head is 1000kg​

Answer 1

Answer:

Explanation:

area on your head=(10×10)cm=

atmospheric pressure=

weight is nothing but force,

PRESSURE=FORCE/AREA

FORCE=PRESSURE×AREA

FORCE=1.01×10^5×100

Force=1.01×10^7 Newton

Hence, the weight on the air that you are carrying will be 1.01×10^7 newtons

Answer 2

Answer:

0.98 Pa

Explanation:

We know that

Pressure = Thrust/Area

Here,

Given,

Length = 10 cm

Breadth = 10 cm

Pressure = 1000 Kg

Area = 10*10 cm^2 = 100 cm^2

Force = 10 kg× 9.8 m/s = 98 N

Therefore,

Pressure = 98/100 Pa = 0.98 Pa
