Question

I need help with two multiple choice questions and number 7, it’s algebra. thank you:)

Answer 1

7)The function relating speed of sound to temperature is

`s(K)\text{ = }\sqrt[]{410K}`

The function relating temperature in kelvin to celsius is

`\begin{gathered} K(C)\text{ = }C\text{ + 2}73.15 \\ We\text{ would find (}SK)(C)\text{ = by substituting }C\text{ + }273.15\text{ into }\sqrt[]{410K} \\ We\text{ have} \\ (SK)(C)\text{ = }\sqrt[]{410(C\text{ + 273.15)}} \\ \text{For C = }30,\text{ we have} \\ (S(K(30)\text{ = }\sqrt[]{410(30\text{ + 273.15)}} \\ =\text{ 352.5 meters per second} \end{gathered}`
