A bus skids for a distance of 25 m with the road pushing on its tires with force of 2000 N as its brakes are applied. What is the change in kinetic energy for the bus?

i agree kid

explanation:

a

what is the question because that is not a question.

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 =
