Aparticle of mass m is attached to a thin uniform rod of length a and mass 4m. the distance of the particle from the centre of mass of the rod is ^. al4 the moment of inertia of the combination about an axis passing through o normal to the rod is (a) ang ma? (b) 22 ma (d) 55 ma? (c) zama?

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.

i need with 1.3.2 investigate cycling o2 and co2 apex

we need to see it

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 =
