Question

A NASA spacecraft measures the rate of at which atmospheric pressure on Mars decreases with altitude. The result at a certain altitude is: Convert to .

Answer 1

`= 4.21* 10^(-10)J/cm^4`

Step-by-step explanation:

According to the given situation, the computation is shown below:-

`1kPa=10^3Pa`

So,

`1Km = 10^5cm`

`1kPa=0.01Pa/Cm`

`1kPa=10^(-8)J/cm^4`

Now as per the question it is given that

r = 0.0421KPa/Km

=
`0.0421KPa/Km * (10^(-8)J/cm^4)/(1KPa/Km)`

after solving the above equation we will get

=
`0.0421* 10^(-8)J/cm^4`

or we can write the above equation in this manner, that is

`= 4.21* 10^(-10)J/cm^4`

Therefore we have solved the equation to reach the right answer.
