A 1.30-m string of weight 0.0125 N is tied to the ceiling at its upper end, and the lower end supports a weight W. Neglect the very small variation in tension along the length of the string that is produced by the weight of the string. When you pluck the string slightly, the waves traveling up the string obey the equationy(x, t)=(8.50mm)cos(172rad⋅m−1x−2730rad⋅ s−1t)Assume that the tension of the string is constant and equal to W. How much time does it take a pulse to travel the full length of the string?What was the weight W?How many wavelengths are on the string at any instant of time?What is the equation for waves traveling down the string?

1. t = 0.0819s

2. W = 0.25N

3. n = 36

4. y(x , t)= Acos[172x + 2730t]

Explanation:

1) The given equation is

The relationship between velocity and propagation constant is

v = 15.87m/s

Time taken,

t = 0.0819s

2)

The velocity of transverse wave is given by

mass of string is calculated thus

mg = 0.0125N

m = 0.00128kg

0.25N

3)

The propagation constant k is

hence

0.036 m

No of wavelengths, n is

n = 36

4)

The equation of wave travelling down the string is

science is a systematic and logical approach to discovering how things in the universe work. true to this definition, science aims for measurable results through testing and analysis. science is based on fact, not opinion or preferences. the process of science is designed to challenge ideas through research.

explanation:

found in the nucleus

has mass of one amu
