Which statement about the effect of temperature on the speed of sound is correct?(1 point)
Responses
As temperature increases, the speed of sound increases because the medium becomes denser.
As temperature increases, the speed of sound increases because the medium becomes denser.
As temperature increases, the speed of sound decreases because molecules in the medium collide less frequently.

A student is using a weak computer to design a logo. If the weak computer is the only constraint, should the student use the online version or downloaded version of a graphic design software?(1 point)
Responses
The online version, because the downloaded version usually requires better equipment than the online version.
The online version, because the downloaded version usually requires better equipment than the online version.
The online version, because the downloaded version may have limited bandwidth that limits how quickly the designer can work.
