What is Atmospheric Pressure in Physics
Atmospheric Pressure in Physics
Atmospheric pressure is measured by barometers.
Atmospheric pressure measured by a simple mercury barometer can be calculated using the formula
p = h g
Standard atmospheric pressure at sea level is usually 76 cm Hg or 10 m water. It can also be expressed as 1 bar.
(Note: cm Hg is an accepted unit of atmospheric pressure. Other similar units involving different liquids are also accepted)
Five books a year is not much, and five minutes to read a day is negligible. Five minutes. So much you need to think about which pizza to order. Or to wait for the kettle to boil. Or read the mailing list from the supermarket. Or read this article. If you increase five minutes to 15 per day, then in a year you will spend 5475 minutes (91.3 hours) reading. In a year, you will read 18.25 books out of 300 pages, and this number can be reduced to 15.
