In the diagram below, a 60-kilogram rollerskater ex-erts a 10-newton force on a 30-kilogram rollerskater for 0.30 second. What is the magnitude of the impulse applied to the 30-kilogram rollerskater

double the distance = divide strength by 4

i believe the answer is electric potential.

explanation:

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 =
