Radiation is s very powerful substance and can cause major health problems do the health care professionals limit the use to help not create sickness
Explanation:
The given data is as follows.
Thickness (dx) = 0.87 m, thermal conductivity (k) = 13 W/m-K
Surface area (A) = 5
, 
According to Fourier's law,
Q = 
Hence, putting the given values into the above formula as follows.
Q = 
= 
= 5902.298 W
Therefore, we can conclude that the rate of heat transfer is 5902.298 W.
In order to determine, Order of reaction, we have to add all the exponents written in the Chemical form, on the Reactant species.
Hope this helps!
