Stokes' law describes sedimentation of particles in liquids and can be used to measure viscosity. Particles in liquids achieve terminal velocity quickly. One can measure the time it takes for a particle to fall a certain distance and then use Stokes' law to calculate the viscosity of the liquid. Suppose a steel ball bearing (density 7.8 x 103 kg/m3, diameter 2.0 mm) is dropped in a container of motor oil. It takes 11 s to fall a distance of 0.65...

One can measure the time it takes for a particle to fall a certain distance and then use Stokes' law to calculate the viscosity of the liquid. Suppose a steel ball bearing (density 7.8 ✕ 103 kg/m3, diameter 3.2 mm) is dropped in a container of motor oil. It takes 11 s to fall a distance of 0.45...
why and how do low pass filters and high pass filters work?
29. In your own words, describe the two processing steps to implement before sterilizing instruments used for patient care.
A certain preparation consists of liquids x, y, and z in the proportion 5:2:1. How many gallons of the preparation can be made from a stock of materials consisting of 25 gallons of x, 20 gallons of y, and 8 gallons of z?
Use the kinetic molecular theory to explain why: -Gases can be compressed much more than liquids or solids. -A blood sample to be analyzed for ammonia gas must be cooled immediately after the blood is drawn from the patient.
Follow-up Question Organic liquids such as hexane can be used as nonpolar solvents, but some have significant vapor pressures at room temperature. The vapor pressure of hexane at 25°C is 169 torr, and hexane's normal boiling point is 69.0℃ Calculate an estimate of the heat of vaporization of hexane.
Explain why the frequency response of discrete-time filters is
always
periodic.
Liquids might be partially miscible, there are miscible only over a certain range of compositions. Verify this statemen using the following figure! AGART
Explain how to choose the two liquids used for an extraction.
