A 3 kg textbook is forced against a horizontal spring of negligible mass andforce constant of 230 N/s, compressing the spring by 0.25 m. When released, the textbook slides on a horizontal tabletop with coefficient of kinetic friction0.35. Use the work-energy theorem to find how far the textbook moves from itsinitial position before coming to rest.

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 =

a. vertically

explanation:

i tried it and took the test

if im wrong then we have different tests

1. metals

2. metalloids only

3. nonmetals only

4. metals and metalloids

5. metalloids and nonmetals

i just took this assignment so this is correct
