Four particles with masses 2 kg, 5 kg, 2 kg, and 2 kg are connected by rigid rods of negligible mass as shown. assume the system rotates in the yz plane about the x axis with an angular speed of 5 rad/s. x y 5 rad/s o 5 rad/s 5 m 5 m 2 kg 5 kg 2 kg 2 kg find the moment of inertia of the system about the x axis. answer in units of kg â· m2 .

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

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 =
