Scientists crossed two different species of fruit trees. This produced offspring whose fruit had characteristics of each parent. What is most likely true about the offspring?

They are the same species as the male parent.
They will not be able to produce offspring.
They are the same species as the female parent.
They will be able to produce offspring.
what is the correct answer?

The space between two 15-in.-long concentric cylinders is filled with glycerin (viscosity = 8.5 × 10-3 lb·s/ft2). the inner cylinder has a radius of 1 in. and the gap width between cylinders is 0.1 in. determine (a) the torque and (b) the power required to rotate the inner cylinder at 180 rev/min. the outer cylinder is fixed. assume the velocity distribution in the gap to be linear.
