Question

The atmospheric pressure is 75 cm of Hg. Express it in N/ sq. m.[Use : density of Hg = 13.6 g/ cu.cm, g= 9.8 m/ sq. s

Answer 1

Answer:

9996×10^4 N/m

Step-by-step explanation:

first you have to convert height and density in metre form

h = 75/100

d = 13.6 × 10^6

so by given relation

P = hdg

P = 0.75 × 13600000 × 9.8

P = 99960000N/m
