Pressure a vertical piston cylinder device contains a gas at an unknown pressure. if the outside pressure is 100 kpa, determine (a) the pressure of the gas if the piston has an area of 0.2 m2 and a mass of 20kg. assume g = 9.81 m/s2. (b) what-if scenario: what would the pressure be if the orientation of the device were changed and it were now upside down

Explanation:

When Cylinder is vertical Let gas pressure inside is and atmospheric Pressure be

Area of Piston

mass of Piston

from FBD

(b)If cylinder is upside down

From FBD

beta is electron from nucleus

something from nucleus has changed, but charge must be same for cons of charge

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
