Question

calculate the pressure at a place is barometric height is 76 centimetre of Mercury and density of mercury is 18.6 kg per metre cube acceleration due to gravity is 9.8 m/s^2

Answer 1

P=density .g.h
..;0.76×9.8×18.6
=127.6pa

Answer 2

Pressure = hdg ……………[Here is the derivation of this formula: https://brainly.in/question/1567673]
= 0.76 m × 18.6 kg/m³ × 9.8 m/s²
= 138.53 Pa

Pressure at that place is 138.53 Pa
