Answer:
T=575.16K
Explanation:
To solve the problem we proceed to use the 1 law of diffusion of flow,
Here,

is the rate in concentration
is the rate in thickness
D is the diffusion coefficient, where,

Replacing D in the first law,

clearing T,

Replacing our values



The formula for average speed is

So we can just substitute our data.

- its the result
North to north repels, south to south repels, north to south attracts, the same vise versa.
The answer is 37 cause the two sides squared and added together equals the hypotenuse squared after that you just find the square root of the answer
