The momentum of an object is determined to be 7.2 ×× 10-3 kg⋅m/skg⋅m/s. express this quantity as provided or use any equivalent unit. (note: 1 kgkg = 1000 gg).

Momentum, p = 720 g-cm/s

Explanation:

The momentum of an object is determined to be,

We need to express this quantity in any equivalent units. We know that the conversions are as follows :

1 kg = 1000 g

and 1 m = 100 cm

p = 720 g-cm/s

So, the momentum of an object in any equivalent unit is 720 g-cm/s. Hence, this is the required solution.

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 =
