Vedclass · Answer

(A) Pressure is defined as force per unit area. Given mass $m = 1034 \ g \ cm^{-2} = 1034 	imes 10^{-3} \ kg \ cm^{-2}$. Area $A = 1 \ cm^2 = 10^{-4} \ m^2$. Force $F = m 	imes g = (1034 	imes 10^{-3} \ kg) 	imes (9.8 \ m \ s^{-2}) = 10.1332 \ N$. Pressure $P = \frac{F}{A} = \frac{10.1332 \ N}{10^{-4} \ m^2} = 10.1332 	imes 10^4 \ N \ m^{-2} = 1.01332 	imes 10^5 \ Pa$.

Pressure is defined as the force acting per unit area of a surface. The $SI$ unit of pressure,$Pascal$ $(Pa)$,is defined as $1 \ Pa = 1 \ N \ m^{-2}$. If the mass of air at sea level is $1034 \ g \ cm^{-2}$,calculate the pressure in $Pascal$.
