Asailor strikes the side of his ship just below the surface of the sea. he hears the echo of the wave reflected from the ocean floor directly below 5.0 s later. how deep is the ocean at this point

3750 m

Explanation:

1) You can find in the literature or internet that the speed of sound in the ocean is about 1500 m/s.

2) Then, you can find the distance travel by the sound wave in 5.0s with the equation distance = speed × time

⇒ distance = 1500m/s × 5.0 s = 7500 m

3) That sound went down until the ocean floor below and cameback all the way until the sailor heard it.

Then, the deep of the ocean fllor is half that distance:

deep = 7500m / 2 = 3750m

probably not if net force is zero

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
