Answer:
0.195 m
Explanation:
Speed is distance moved per unit time, expressed as s=d/t and making d the subject of the formula then d=st
Where d is distance/depth moved, s is rhe speed of waves and t is time in seconds.
Substituting s with 1300 m/s and t with 0.00015 s then the depth of metal segment will be
D=1300*0.00015=0.195 m
Therefore, the depth is equivalent to 0.195 m
Answer:
The speed of the wave is 3 m/s.
Explanation:
Given that,
Number of waves = 6
Time = 8.0 s
Successive crests
We need to calculate the frequency
Using formula of frequency
Put the value into the formula
We need to calculate the speed of the wave
Using formula of speed
Put the value into the formula
Hence, The speed of the wave is 3 m/s.
