It is found that a 5.70 m segment of a long string contains three complete waves and has a mass of 180 g. the string is vibrating sinusoidally with a frequency of 55.0 hz and a peak-to-valley distance of 19.0 cm. (the "peak-to-valley" distance is the vertical distance from the farthest positive position to the farthest negative position). calculate the wavelenght.

wavelength = 3.8 m

Explanation:

As we know that linear mass density is defined as the ratio of mass and length

so here we have

now we have

Now it is given that string contains three complete waves

length of one segment on string is half of the wavelength

so here we have

So wavelength of the wave on string is 3.8 m

spare some change and give it to the poor

explanation:

plz : ((

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
