A 24.0 kgkg box is held at the top of a 9.40 mm long delivery ramp that makes a 17.0 degreedegree angle with the horizontal. When the box is released, it slides down the ramp, with a constant 48.0 NN frictional force exerted on it over the full 9.40 mm . What kinetic energy does the box have at the bottom of the ramp?

elctricity and magnet is conversion to 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 =
