The pressure inside a bottle of champagne is 2.5 atm higher than the air pressure outside. the neck of the bottle has an cross sectional area of 3.0 cm^2. what is the frictional force on the cork due to the neck of the bottle?

To solve this problem it is necessary to apply the concepts related to Pressure, Strength and Area.

We know by definition that Pressure is the amount of Force expressed per unit area, that is,

Where,

F = Force

A = Cross-sectional Area

The net pressure on the bottle would be given by the difference between the internal pressure and the atmospheric pressure, therefore

The given radio is,

Hence the Cross-sectional Area would be

Applying the equation for Pressure we have that

Therefore the frictional force on the cork due to the neck of the bottle is 429.66N.

there is no correct list among the choices you've provided.

the list might look something like this:

-- baby human

-- piccolo

-- flute

-- soprano singer

-- trumpet

-- tenor singer

-- trombone

-- baritone singer

-- baritone horn

-- bass singer

-- tuba

since i had to make up the list myself, i made it easy on myself, and i didn't try to shuffle the string instruments and woodwinds into it too.

find the surface area of the sphere to the nearest square unit. use a calculator.

a. 254 in.2

b. 64 in.2

c. 127 in.2

d. 1,018 in.2
