the object con tinues to fall but with NNO acceleration! notice that there is not net force if the upward and dowward forces are equal.
This is a big looking question for school and for 5 points.It seems to relate to superfluidity in helium III and helium IV and something called the "lambda" point. Though I can't do it justice yet and here, it looks as though i can find tis in "Heat and Thermodynamics", Mark W Zemansky ...If rho is the density of helium II, rhon the density of the normal part, and rhoz the density of the superfluid part rho=rhon+rhoz.At the lambda point, all the atoms are normal and rhon/rho = 1, whereas at absolute zero all the atoms are superfluid and rhon/rho=0.Best I can do with the info and point available ..ps, I think that both Bose and Einstein were nobel prize winners, and the word "Boson" is in honour of the, I believe, Indian physicist Bose. It is a very interesting question, and I can in no way do it justice here.

highest is C.
Answer:
5833.33
Explanation:
= Angular acceleration
= Number of revolutions
= Initial angular speed = 0
t = Time taken = 2 s
Final angular speed
From the equation of rotational motion we have
The number of revolutions is 5833.33
