Along with the separation techniques discussed in class, chromatography is another one. We learned that we use the physical properties of substances in mixtures to separate them. Which physical property do you think was used to separate the dyes in your ink? Explain

distance = 150m

displ = root (50 ^2 + 100^2)

root(2500+10000)

root 125000

at right angles to each other

earth's neighboring galaxy, the andromeda galaxy, is a distance of 2.54×107 light-years from earth. if the lifetime of a human is taken to be 70.0 years, a spaceship would need to achieve some minimum speed min to deliver a living human being to this galaxy.
