There are three main methods for determining viscosity: the
Ostwald viscometer, the falling ball viscometer, and the cup
viscometer. Briefly describe how each method works.
(a) Estimate the terminal speed of a wooden sphere (density
0.870 g/cm3) falling through air, if its radius is 8.00 cm and its
drag coefficient is 0.500. (The density of air is 1.20
kg/m3.)
Incorrect: Your answer is incorrect.
Your response is within 10% of the correct value. This may be due
to roundoff error, or you could have a mistake in your calculation.
Carry out all intermediate results to at least four-digit accuracy
to minimize roundoff error. m/s

(a) Estimate the terminal speed of a wooden sphere (density
0.790 g/cm3) falling through air, if its radius is 7.50 cm and its
drag coefficient is 0.500. (The density of air is 1.20 kg/m3.)

(b) From what height would a freely falling object reach this
speed in the absence of air resistance?

Consider a medium viscosity liquid silicon polymer: Use building
blocks Me3SiCl, Me2SiCl2 and MeSiCl3.
You will need to decide what ratios to use,the procedure, what
order to add them, and what conditions.

interviews subject about their dietary intake and their medical
history and also draws blood from each other. 2. Mary finds that
she does better on tests if she has carbohydrates prior to the
exam. She wonders if the carbohydrates is really improving her
performance and considers doing a study.
