An aluminum sphere (specific gravity = 2.70) falling through water reaches a terminal speed of 8.36 cm/s. what is the terminal speed of an air bubble of the same radius rising through water? assume viscous drag in both cases and ignore the possibility of changes in size or shape of the air bubble; density of air at 20°c is 1.20 kg/m3 and that of water is 998.21 kg/m3.

What is the final velocity of the initial velocity of 25 and -50?

The difference between a red shift and a blue shift has to do with wavelength frequency. t or f
