You wish to capture particles with a 3 µm radius suspended in a fluid that has a linear density gradient with a density of 1.12 g/cm^3 at the bottom and 1.00 g/cm^3 at the top. you layer a thin particle suspension on the top of the 6 cm column of fluid with a viscosity of 1.0 cp and allow particles to settle.
a) how long must you wait for particles with a density of 1.07 g/cm^3 to sediment to within 0.1 cm of their isopycnic level (i. e., within 0.1 cm of the position where the density of the particles and the density of the fluid are equal)?
b) instead of settling due to gravity, you choose to use a centrifuge running at 800 rpm. if the top of the fluid is 5 cm from the center of rotation, how long must you run the centrifuge for the particles to move to within 0.1 cm of their isopycnic level?

d would be the most obvious choice to this question. leaders are supposed to herd their underlings like a shepherd to sheep. a leader should also listen to others when they are talking to one other to gain a better understanding of their mission and surroundings.

explanation:

One of the benefits of working with chlorinated polyvinyl chloride (CPVC) pipe is that it can be cut with a variety of different tools that don’t require any electricity or heat. However, different cutting methods are preferred over others, depending on the application.

When cutting CPVC pipe, it is important to make a square, flat cut. An uneven cut limits the bonding area and weakens the fitting.

To help you make the best possible cut, we’ve put together the following dos and don’ts when cutting CPVC pipe in different situations.
