Question

H=140 Pn=760 мм рт ст p-?

Answer 1

p= pa- h/12 =>

p= 760- 140/12= 748 мм.рт.ст.

Answer 2

It seems like you have provided two pieces of information: H=140 and Pn=760 mmHg (which I assume is the pressure at sea level). And you want to find the pressure denoted as "p."

The relationship between atmospheric pressure and altitude (height) is typically described by the barometric formula. However, since you have not specified the unit for "H," I'm unable to calculate the pressure accurately. The barometric formula requires the altitude or height above sea level to calculate the atmospheric pressure at that location.

If you provide the unit for "H" (whether it's in meters, feet, or another unit), I'll be able to help you calculate the pressure denoted as "p" using the barometric formula.
