Homework Answers
Barometer reading at location in height of mercury column is given.the temperature of the mercury is 10°c.the density of the mercury is 13570kg/m^3.
Atmospheric pressure = density×acceleration due to gravity×height of mercury column
Patm= 13570×9.81×0.9
=119809.53pa
=119.809 Kpa
Option C is correct
