The sonar pulse takes t=4.2 s to reach the ocean bottom and then to travel back tothe ship. If we call d the depth of the ocean bottom, this means that the sonar pulse covered a distance equal to 2d in a time of 4.2 s.
The speed of the sonar pulse is the speed of sound in water at 25C, so looking at the table is v=1493 m/s. Using the relationship
between space and time for a uniform motion, and keeping in mind that the total distance covered by the pulse is 2d, we can write:
which becomes
so, the ocean bottom is 3135 m deep.
Answer:
350 m/s
31°C
Explanation:
Speed of sound is given as the product of frequency and wavelength
S=fw
Where s represent the speed in m/s, f is frequency and w is wavelength
Conversion
Taking 1m to be 100 cm then 35 cm will be 35/100=0.35m
Substituting 0.35 m for w and 1000 Hz for f then
S=1000*0.35=350 m/s
speed of sound (m/s) = 331.5 + 0.60 T(°C)
350=331.5+0.6T
T=30.833333333333
The temperature is approximately 31°C
Explanation:
2. v=fλ
