Answer :
Final answer:
To find the atmospheric pressure using a closed bulb mercury manometer filled with gas, apply the equation p = hpg where h is the height of the fluid, p is the density of the fluid, and g is acceleration due to gravity. Given specific values, the atmospheric pressure can be calculated to be around A) 95.4 kPa.
Explanation:
The atmospheric pressure can be calculated using the equation:
p = hpg
Given that the height difference of mercury in the manometer is 1.93 cm, and the density of mercury is 13540 kg/m³, we can find the atmospheric pressure to be approximately 95.4 kPa.
