The speed of a transverse wave( v) = 117.03 m/s
The formula we can use in this case would be:
v = sqrt (T / (m / l))
Where,
v = is the velocity of the transverse wave = unknown (?)
T = is the tension on the rope = 380 N
m = is the mass of the rope = 86.0 g = 0.086 kg
l = is the length of the rope = 3.1 m
Substituting the given values into the equation to search for the speed v:
v = sqrt (380 N/(0.086 kg /3.1 m))
v = sqrt (380 * 3.1/ 0.086)
v = sqrt (13,697.67)
v = 117.03 m/s
speed of a transverse wave( v) = 117.03 m/s

Answer:
1.2703 km
Explanation:
The speed can be calculated using the formula;
Speed (m/s) = distance (m) ÷ time (s)
Based on the information in this question, it took 3.7 seconds for a sound with speed of 1236 km/h to reach John. The distance will be:
Distance = speed × time
However, we need to convert the time in seconds (s) to hour (hr).
1 second = 0.000277778 hour
3.7 seconds = 0.00102778 hours.
Hence,
distance = 1236 × 0.00102778
Distance = 1.2703 km
