Which of the following is a possible application of a centrifuge? (More than one answer may be correct.)

Test astronaut’s tolerance for high accelerations

Produce even mixtures of particles of different densities

Separate human blood cells

Speed sedimentation of dirt particles

Mimic conditions on the International Space Station

I think it should be all of them...is this right?

nope, two of them are ridiculous.
ok, is it the one about the densities?

And then possibly the blood cells? I know it can separate human blood cells from plasma, but I don't know if the question refers to this or to physically splitting the cells themselves (which is impossible).
the blood cells separate, as does the plasma, because they are different densitities. So that one is caused by centripetal force.
What makes you believe the ISS is spinning? That would make very difficult pointing of the solar arrays.
EVEN mixtures?
