Explanation:
I think it will increase a little bit ... just image ... if the temperature is 0, the velocity will be 0 too. because the vibration of atom is so weak and the sound cant progation.

b

Explanation:
From the question we are told that
The wavelength is 
The number of antinodal planes of the electric field considered is n = 5
The width is mathematically represented as



Generally the frequency the errors was made is mathematically represented as

Here c is the speed of light with value 
is the wavelength of the microwave has to be in order for there still to be five antinodal planes of the electric field along the width of the oven, which is mathematically represented as


So
