In the table below, data for a newly studied star, Excalibur, and some of the planets surrounding it are displayed. The planets follow nearly circular paths around the central star. Examine the data and
diagram provided and determine which of the planets exerts the largest gravitational force on
Excalibur.
Write a scientific explanation that give mathematical evidence to support your claim and provides reasoning based on newton’s law of universal gravitation.

answer: i'm not sure which is which for i get confused on it all the time but i can tell you that the answer lies with the convex and concave devices. i hope this you. have a good day and best of luck to you!

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 =
