One tsunami, generated off the Aleutian islands in Alaska, had a wavelength of 600 km and traveled a distance of 3700 km in 5.3 h Screen Shot a) What was the speed (i m/s) of the wave?

My Notes Ask Your Teacher 2016-04...0.40 PM The mass of a string is 2.40 x 10-3 kg, and it is stretched so the tension in it is 200 N. A transverse wave traveling on this string has a frequency of 260 Hz and a wavelength of 0.60 m. What is the length of the string? Additional Materials Screen Shot 2016-03...4.06 PM Section 16.3Explanation / Answer
(a)
= 600 * 10^3 m
Speed, v = Distance/time
v = (3700 * 10^3)/(5.3 * 3600) m/s
v = 193.9 m/s
(b)
v = f *
f = v/
f = 193.9/(600 * 10^3)
f = 3.23 * 10^-4 Hz
(c)
t = 1/f
t = 1/ (3.23 * 10^-4 )
t = 3096 s
(4)
m = 2.4 * 10^-3
T = 200 N
f = 260 Hz
= 0.6 m
f* = sqrt(T/(m/L))
260 * 0.6 = sqrt(200/((2.4 * 10^-3)/L))
L = 0.29 m
