in a satellite , atmospheric pressure was observed to be 2 x 10(to power of -9) mbar . what fraction is this of the earth's atmospheric pressure ?

Dear student

Standard atmospheric pressure on earth at sea level is approx. equal to 1000 mbar.

So in a satellite if teh value of P is 2 x 10^-9 mbar, then it will be 2 x 10^-12th of the earth's atm pressure value.

One can arrive at this value by simply dividing 2 x 10^-9 by 1000.

 

We hope this clarifies your query.
