Which materials are present in an NPN transistor?

A. all negative type semiconductor materials on a positive plate

B. all positive type semiconductor materials on a negative plate

C. an n-type semiconductor sandwiched between p-type semiconductor materials

D. a p-type semiconductor sandwiched between n-type semiconductor materials

D

Explanation:

a p-type semiconductor sandwiched between n-type semiconductor materials

the maxium height is 34m/s

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 =
