=> 
A mechanical wave can only travel through matter.
A soft metal core made into a magnet by the passage of electric current through a coil surrounding it.
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
