A 3.47-m rope is pulled tight with a tension of 106 N. A wave crest generated at one end of the rope takes 0.472 s to propagate to the other end of the rope. What is the mass of the rope (in kg)

The mass of the rope is 1.7 kg.

Explanation:

Given;

length of the rope, L = 3.47 m

tension on the rope, T = 106 N

period of the wave, t = 0.472 s

frequency of the is calculated as;

the speed of the wave is calculated as;

where;

v is speed of the wave = fλ

λ is the wavelength

μ is mass per unit length

Therefore, the mass of the rope is 1.7 kg.

i would say the answer is food.

hope this !

answer: b.
