Question

A transverse wave is traveling through a canal. If the distance between two successive crests is 3.47 m and four crests of the wave pass a buoy along the direction of travel every 13.1 s, determine the following.

(a) frequency of the wave
______Hz

(b) speed at which the wave is traveling through the canal
_____m/s

QUESTION 2

A 0.470 kg mass suspended from a spring oscillates with a period of 1.50 s. How much mass must be added to the object to change the period to 2.00 s?

_____kg  

PLEASE ANSWER ALL THE QUESTIONS DONT GIVE ANY WRONG ANSWERS THANKS FOR YOUR HELP !

Explanation / Answer

According to the given problem,

1.)

a)Frequency = 4/13.1 = 0.3053 Hz
b)Wavelenght = 3.47 m
Speed = Frequency X Wavelenght .
Speed =0.3053 * 3.47
Speed=1.05954 m/s

2.) T = 2m/k

T intial = 20.47/k = 1.50

k = 8.2466N/m

T final = 2 s = 2m/8.2466

m = 0.83555kg and the mass added is = 0.83555-0.470 = 0.3655 kg
