Answer:This Answer is B
Explanation:
Longitudinal waves have the same direction of vibration as their direction of travel. This means that the movement of the medium is in the same direction as the motion of the wave. Some longitudinal waves are also called compressional waves or compression waves.
Answer:
The average force exerted on the pier is N
Explanation:
Given :
Mass of ship Kg
Distance m
Velocity
Now find the average velocity,
Now find the time taken by ship to travel 4.44 m.
sec
Now calculating average force,
Where = 0.652
N
Therefore, the average force exerted on the pier is N
When waves travel across strings, the larger the tension of the string the faster the velocity of the wave. This is because of the equation:
v = the square root of (T/(m/L)) where T is the tension, m the mass of the string, and L the length of the string
