An ideal gas in a cylinder occupies a volume of 0.065 m3 at room temperature (t = 293 k). the gas is confined by a piston with a weight of 100 n and an area of 0.65 m2. the pressure above the piston is equal to one atmosphere (atm = 1.013x105 pa). the piston is free to move up and down. 1) what is the magnitude of the net force on the piston? zero 50 n 100 n 2) briefly explain your answer.

zero

Explanation:

There are three forces acting on the piston

1. force due to atmospheric pressure = F1 downward

2. force due to gaseous pressure = F2 upward

3. force due to the weight placed on the piston = F3 = mg downward

As the piston is in equilibrium condition, so the net force on the piston is zero.

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.

gas and liquid
