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
Answer:
The apparent weight of the person as she pass the highest point is
Explanation:
From the question we are told that
The radius of the Ferris wheel is
The period of revolution is
The weight of the person is
Generally the speed of the wheel is mathematically represented as
substituting values
The apparent weight (the normal force exerted on her by the bench) at the highest point is mathematically evaluated as
Where m is the mass of the person which is mathematically evaluated as
substituting values
So
