Answer:
0.737 m/s²
Explanation:
Given:
v₀ = 0 m/s
v = 8.20 m/s
Δx = 45.6 m
Find: a
v² = v₀² + 2aΔx
(8.20 m/s)² = (0 m/s)² + 2a (45.6 m)
a = 0.737 m/s²
The answer would be c. hope this helps☺
Answer:
d = 4180.3m
wavelengt of sound is 0.251m
Explanation:
Given that
frequency of the sound is 5920 Hz
v=1485m/s
t=5.63s
let d represent distance from the vessel to the ocean bottom.
an echo travels a distance equivalent to 2d, that is to and fro after it reflects from the obstacle.


wavelengt of sound is
= v/f
= (1485)/(5920)
= 0.251 m
