Question

Water waves in a tank are 10 cm long. If they pass a point at a rate of 3.75 waves per second, what is their speed in m/s?

Answer 1

Answer: 0.0267m/s

Step-by-step explanation: Hence the speed of the wave in m/s is 0.0267m/s because the Length of the wave = 10cm = 0.1m

Wave speed in m/s

Speed = Distance/Time

Substitute the given values into the formula

Speed = 0.1/3.75

Speed = 0.0267m/s

Answer 2

0.0267m/s

Explanation:

Given the following

Length of the wave = 10cm = 0.1m

Time taken = 3.75seconds

Required

Wave speed in m/s

Speed = Distance/Time

Substitute the given values into the formula

Speed = 0.1/3.75

Speed = 0.0267m/s

Hence the speed of the wave in m/s is 0.0267m/s
