. When two speakers play different sounds with a constant frequency, beats are heard with a frequency of 5 Hz. If the frequency of sound played by one of the speakers is 1050 Hz, what is the frequency of sound played by the other speaker

The beat frequency is the concept required to develop this process. The phenomenon is generated when you have two waves but their frequencies do not differ greatly. So the beat frequency will be the difference between those two waves. For this case we have the difference and one of the waves, therefore,

Our values are given as,

Using the formula of the frequency I will have,

Replacing we have,

The possible values are two: 1045Hz and 1055Hz

answer: the metamorphic rocks are formed when they are exposed to high pressure and high temperatures. this happens when one of the earth's plates comes in contact with the other plate by traveling in opposite directions, straight into each other or slipping under one another. the friction that is caused by this activity results in   melting of rocks and when it cools they are known as metamorphic rocks. this process needs a controlled amount of pressure and temperature otherwise it may turn into magma.

pretty sure it's false
