Saturn orbits the Sun at a distance of 1.43 *10^12 m. The mass of the Sun is 1.99 * 10^30 kg.
Use (equation in picture) to determine Saturn's orbital period in Earth years.
Gm
29.6 Earth years
296 Earth years
874 Earth years

the answer would be c. motion and direction

i hope this : )

the answer would be c

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 =
