A sound wave travels a distance 1020 m in 5 minutes. If the length of the three successive crests is 15 m, then calculate the wave speed.
"Length of three crests"? I'm not sure about that.
To calculate the wave speed, we need to use the formula:
Wave speed (v) = Distance (d) / Time (t)
In the given question, we are given the distance traveled by the sound wave (d = 1020 m) and the time it took to travel that distance (t = 5 minutes). We can substitute these values into the formula to find the wave speed.
v = 1020 m / 5 min.
However, before we can proceed with the calculation, we need to convert the time from minutes to seconds since the standard SI unit for time is in seconds. To do this, we can multiply the time by a conversion factor of 60 seconds per minute.
t = 5 min * 60 s/min
t = 300 s
Now, we can substitute the values into the formula:
v = 1020 m / 300 s
Simplifying the calculation will give us the wave speed:
v = 3.4 m/s
Therefore, the wave speed is 3.4 meters per second.
