Students in ms. bailey's class were studying speed. four students rolled balls across the floor a distance of 30 cm. their times are seen here. put the times in order from fastest to slowest. a) ball 1 - ball 2 - ball 3 - ball 4 b) ball 1 - ball 2 - ball 4 - ball 3 c) ball 2 - ball 1 - ball 4 - ball 3 d) ball 4 - ball 3 - ball 2 - ball 1

shows up as a (purple)/ (flashing) red or blue dot getting bigger and brighter.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
