Answer:

$= 4.21\times 10^{-10}J/cm^4$

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

= $0.0421KPa/Km \times \frac{10^{-8}J/cm^4}{1KPa/Km}$

after solving the above equation we will get

= $0.0421\times 10^{-8}J/cm^4$

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

$= 4.21\times 10^{-10}J/cm^4$

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