A machine having efficiency of 40% is used to lift a load of 1200N threat a height of 10M and of 30M in 5 second. calculate. A, Effort. B, mechanical advantage C, velocity ratio D, input work. E, output work. F, input power. G, output power H, wasted energy. i, efficiency​

answer: a. same unit

explanation:

i'm on my way to history not a mistory.

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 =
