The answer to this question is A. As the gas gets hotter, the molecules gain energy and move farther apart, causing the gas to expand. This is because, whenever you heat a substance, (solid, liquid, or gas), the molecules in the substance will always move more rapidly causing the substance to expand and the molecules to move further away from one another.
B)Mechanical waves tend to have longer wavelengths
Sound is a mechanical wave. Wavelength and frequency are inversely related. So, Mechanical waves tend to have longer wavelengths.
Use the slope equation. It’s 1-8 Meters which is 7. And it’s 22-14 seconds. So the answer is d

Answer:
The maximum temperature is 90.06° C
Explanation:
Given that
t= 0.1 mm
Heat generation
Heat transfer coefficient
Here one side(left side) of the wall is insulated so the all heat will goes in to right side .
The maximum temperature will at the left side.
Lets take maximum temperature is T
Total heat flux ,q
So the total thermal resistance per unit area
R=0.002 K/W
We know that
q=ΔT/R
30=(T-90)/0.002
T=90.06° C
The maximum temperature is 90.06° C
