A 2.5 kg object has an acceleration of 4 m/s2. What is the force of the object?

Force = Mass × Acceleration

Mass = 2.5 kg

Acceleration = 4 m/s^2

Force = 2.5 × 4

Force = 10 N

The force of the object is 10 N

where is the photo and the answer choices?

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 =
