Paul works for a supermarket and is pushing a wooden box of supplies across the supermarket floor. If the coefficient of kinetic friction between the crate and the floor is 0.2 and the kinetic friction between the floor and the
crate is 18 newtons, what is the normal force acting on the crate?

lol

explanation:

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 =

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
