A sound has a higher pitch than a bell. Which quantity must also be higher in this sound than in the bell?
speed
wavelength
amplitude
frequency
Frequency.
Which statement regarding sound traveling in air is correct?
As the wavelength increases, the frequency also increases.
A wave with a shorter wavelength is always faster than one with a longer wavelength.
The frequency of a sound does not affect the speed at which it travels.
A loud sound travels faster than a quiet sound.
The frequency of a sound does not affect the speed at which it travels.
Which statement about the effect of temperature on the speed of sound is correct?
As temperature increases, the speed of sound increases because the medium becomes denser.
Changes in temperature have no effect on the speed of sound.
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.
As temperature increases, the speed of sound decreases because molecules in the medium collide less frequently.
As temperature increases, the speed of sound increases because molecules in the medium collide more frequently.

microwaves, infrared, ultraviolet, gamma rays.
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?
The downloaded version, because the online version usually requires better equipment than the downloaded 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.
