Jake uses a fire extinguisher to put out a small fire. when he squeezes the handle, the flame rettardant is released from the extinguisher with considerable force. as a result, jake has to reinforce his grip on the extinguisher to hold it in place as it pushes back into his hands. the projectile in this scenario is the . the recoil in this scenario is the . the force on the flame rettardant is the force on the extinguisher. the mass of the flame rettardant is the mass of the extinguisher. the acceleration of the flame rettardant is the acceleration of the extinguisher.

The projectile in this scenario is the flame r.

The recoil in this scenario is the extinguisher.

The force on the flame r is equal to the force on the extinguisher.

The mass of the flame r is less than the mass of the extinguisher.

The acceleration of the flame r is greater than the acceleration of the extinguisher.

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 =
