b) 5/3 m/s
Explanation:
For constant speed V at the interface of the two fluids the net force is zero.
Hence, F top = F bottom thus the shear stresses at top and bottom must be the same.
For force of top plate

Explanation:
COP is the coefficient of performance of refrigerator and Heat pump
COP of refrigerator is given by
cooling effect/work input =
And for ideal refrigeration cycle
COP=
COP of heat pump is given by
Heating effect/ work input =
And for ideal Heat pump cycle
COP=
Now, we can conclude that
