The force on the inside of a cork in a champagne bottle is 10 pound-force [lb Subscript f]. If the cork has a diameter of 0.5 inches [in], what is the pressure inside the bottle in units of feet of water [ft Upper H 2 Upper O]?

117.48 is the pressure inside the bottle in units of feet of water.

Explanation:

Diameter of the cork = d = 0.5 inch

Radius of the cork = 0.5 d  = 0.25 inch  =

1 inch =  0.0254 m

Area of the cork :

Force on the cork , F= 10 pound-force = 44.4822 N

1 Pound Force = 4.44822 Newton

Pressure on the cork :

1 Pa = 0.00033455256555148 feet water

feet water

Pressure = 117.48 feet of water

117.48 is the pressure inside the bottle in units of feet of water.

your answer is c) plasma

the correct answer would be b. amelia, because the particals of gas move really fast (charged particals) and gas also has a lot of room (particals move independently) so the only answer that has both of those is amelia's.
