Use the following problem for each item in this section: A lever has an input force of 8 newtons and an output force of 28 newtons. What is the mechanical
advantage of the lever?

What form of the equation for mechanical advantage should be used to solve this problem?

• MA= Fo/Fi
• Fo= (MA)(Fi)
Fi=Fo/ MA

What is the mechanical advantage?

MA= 0.29J
MA=3.5 watts
MA= 3.5
MA=224

answer; how far out of place which the object finished relative to the starting location;

answer: 31, 5556. 952 seconds

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 =
