Tectonic plates are large segments of the earth's crust that move slowly. suppose that one such plate has an average speed of v = 4.1 cm/year no attempt 50% part (b) enter an expression, in terms of v and numeric values, that gives the plate's speed in kilometers per million years.

another example of kinetic energy would be,

kinetic energy   >     moving energy

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

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 =
