On the surface of earth, a spacecraft has a mass of 2.00 x 104 kilograms. what is the mass of the spacecraft at a distance of one earth radius above earth's surface?

Mass will be same as

Explanation:

We have given mass of the spacecraft kg on te earth

We have to find the the mass of the spacecraft at a distance one earth radius from the surface of earth

As we know that mass is always conserved it does nit depend on the gravity when spacecraft goes above the earth only acceleration due to gravity is change and it has no effect on mass

So mass will remain same

So mass will be

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 =
