Waves on a String: The speed of sound in steel is 5000 m/s. What is the wavelength of a sound wave of frequency 660 Hz in steel

The wavelength of the sound wave is 7.58 m

Explanation:

Given;

speed of wave in steel, v = 5000 m/s

frequency of the wave in steel, f = 660 Hz

The wavelength of a sound wave is given by;

λ = v / f

where;

v is the speed of sound wave in steel

f is the frequency of sound wave in steel

λ is the wavelength of the sound wave in steel

λ = 5000 / 660

λ = 7.58 m

Therefore, the wavelength of the sound wave is 7.58 m

f=ma newton

f=100x2.5=250n

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.
