Question

if the standard barometer reading of 760 millimeter off mark for respond to pressure of 10 to the power 5 Pascal acting on the surface of mercury in there is a way what is atmospheric pressure in Pascal when the Barometer reads 570 mm of Mercury

Answer 1

1atm = 760mm of Hg = 10^5 Pa[ exact value is 1.01325*10^5 Pascal.]
760 mm = 1atm
So, 570 mm = 570/760atm = 3/4 atm = 0.75atm
1atm =10^5 Pa
So 0.75 atm = 0.75* 10^5 Pa = 7.5* 10^4 Pascal.

Answer 2

Answer :

0.75 × 10⁵ Pa

Explanation:

$here \\ \: 760mm \: of \: hg \: = {10}^{5} pa \\ when \: barometer \: reads \: 570mm \: the \: pressure \: is \\ ( \frac{570}{760} \times {10}^{5} )pa \\ = \frac{3}{4} \times {10}^{5} pa \\ = 0.75 \times {10}^{5} pa$
