A curumim, bored because of the flood that flooded the backyard of his house, observes from the door the waves coming from a wake caused by a vessel. With the help of a clock and, taking as reference part of the fence that emerges from the water, he verifies that thirty wave crests pass in a minute. He also observes that a certain crest of this wave travels the distance between the fence and the stairs of his house in two seconds. Assume that the distance between the fence and the stairs is 10 m and that the amplitude of this crest is not damped. Therefore, the length of this wave and its propagation speed are, respectively:a.
15 m e 15 m/s
b.
15 m e 10 m/s
c.
30 m e 10 m/s
d.
15 m e 5 m/s
e.
30 m e 5 m/s
