A pendulum has a time period of 3.0s and an amplitude of 0.10m. Calculate (a) its frequency (Formula = 1/time)​

i believe the answer would be:

d. violin, clarinet, french horn, and tuba

f=ma newton

f=100x2.5=250n

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 =
