An object traveling 10 m/s collides with an object of the same mass that was originally at rest. After the collision, the two
objects stick together. If there are no other forces acting on the
objects, what is the final velocity of the objects?

23 points

1/0.14nm = 10^10/1.4 a lot

so easy. just google the electromagnetic waves and it’ll pop up.

e/c, where e is its total energy

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 =
