Explain why someone driving a modern vehicle is more likely to survive a car accident than someone driving a classic car (50 years old or older). assume the details of the crashes are the same other than the type of vehicle being driven

i would think form in reponse to tensional forces

gravity

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 =
