Answer:

Incomplete question but the closest ans is

A) The displacement is not zero

Explanation:

For work to be done, the direction of force has to be parallel to or in the same direction as the displacement, this can then be calculated by

W=Fs   \ cosθ

Where θ is the angle between direction of force and direction of displacement

By this equation,

if Force is zero, W is zero

if displacement is zero, W is zero

if force and displacement are perpendicular θ=90, cosθ = 0

So A is the cloest choices

The weight of the mass added to the hanger is equal to the extra force on the gas, but what area should we use to calculate the
kari74 [83]

Answer: according to the Avagadro's law, volume is directly propotional to no of moles: VXn

according to the Charles law, volume is directly propotional to  temperatue: VXT

according to the Boyle's law, volume is inversely propotional to P: VX1/P

when we combine them we get:

VXnT1/P

V=knT/P

k= R(universal gas constant)

V=RnT/P

PV=nRT

How much heat is released when 12.0 grams of helium gas condense at 2.17 K? The latent heat of vaporization of helium is 21 J/g.
uranmaximum [27]
To determine the heat released by the process of condensation, we simply multiply the amount of the gas that condensed to the latent heat of vaporization. We do as follows:

Heat released = 21 J/g (12.0 g ) = 252 J of heat released

A 1.5 kg tether ball is hit so that it circles the pole with an angular speed of 4m/s
My name is Ann [436]

Well, you didn't ask a question, and 4 m/s is not an angular speed.
So all I can offer is a couple of observations:

1). The tension in the rope is

      M V² / R  =  (1.5 kg) x (4 m/s)² / R

                     =  (24 kg-m²/s²) / (distance of the ball from the pole).

2).  Tetherball was the only thing I played at camp,
       more than 60 years ago, and I loved it !
       It was a tough game, because we had to skin
       our own T.Rex and use his hide to make the ball
       and his guts for the rope.
