Does the higher the amplitude of a wave mean the quieter it sounds?
True
How does changing the position of a moving object change it's sound?
The nearer the source of sound, the louder is the sound. If the source of sound is far away from the listener, the intensity of sound decreases, by the square of the distance. ++++ Also, the Doppler Effect. The sound of something approaching at speed, such as the horn on a fast-moving railway locomotive, or a police-car siren, is raised in pitch above its true frequency, then drops abruptly to below true as it passes you. This is due to the sound source moving but the sound speed in air remaining constant.
As a moving object's velocity decreases its momentum decreases?
True
As a moving object's velocity decreases does its momentum decreases?
true
When A wave transfers energy true or false?
The answer is true. The greater the energy the greater the amplitude.
The greater the amplitude of a sound wave the louder the sound True or false?
True.
Increasing the intensity of light decreases the rate of photosynthesis true or false?
false
Does the higher the amplitude of a wave mean the quieter it sounds?
True
What does the brightness of light depend on?
The ultraviolet light contains photons of high energy. these are able to excite the atoms. which during the process of de-excitation can emit frequencies , which are detectable by normal eye. So it depends upon frequency of light..
One sound can appear louder or softer than a second sound with an equal intensity?
True
When the temperature of a medium increases the speed of sound decreases true or false?
No it is not true. When the temperature of the medium increases the speed of sound in that medium increases.

Loud sounds are caused by bigger vibrations than quiet sounds truefalse?
partly true. increases in the amplitude of a sound wave will generally make that sound wave sound louder, but sound volume is a least partly subjective. two different frequencies with the same mechanical amplitude might sound like they are at very different volume levels because of the way the ear and brain process sound information.
In general how does changing the temperature of a medium affect the speed of sound through that medium?
As the temperature of the medium increases, so does the speed of sound. As the temperature decreases the speed of sound decreases (this is true for air, at least). To calculate speed of sound in air: V = 331 + 0.59T where T is the air temperature in degrees C.
