Question

calculate the pressure exerted by the column of mercury 7mm on the button of barometer.(density of mercury is 13600 kg/m)​

Answer 1

Answer: 932960P

Step-by-step explanation:

The formula to calculate pressure is:

= density × g × h.

where,

g = acceleration due to gravity = 9.8

h = height of mercury = 7

Therefore, pressure will be:

= 13600 × 9.8 × 7

= 932960P
