Answer As a wave travels across the open ocean, it gains speed. When a wave reaches a shallow coastline, the wave begins to slow down due to the friction caused by the approaching shallow bottom. ... Think of it like driving a car at high speed and then slamming on the breaks. Everything is going to fly to the front.:Waves at the Shoreline: As a wave approaches the shore it slows down from drag on the bottom when water depth is less than half the wavelength (L/2). The waves get closer together and taller. ... Eventually the bottom of the wave slows drastically and the wave topples over as a breaker. hope this helps have a nice night❤️❤️❤️
Explanation:
Answer:same
Explanation:
Given
ball A initial velocity=3 m/s(upward)
Ball B initial velocity=3 m/s (downward)
Acceleration on both the balls will be acceleration due to gravity which will be downward in direction
Both acceleration is equal
For ball A
maximum height reached is
After that it starts to move downwards
thus ball have to travel a distance of h_1+h(building height)
so ball A final velocity when it reaches the ground is
For ball b
thus
The effort applied = 200 N
<h3>Further explanation</h3>Equilibrium :
Total length = 1.75
The distance between the fulcrum and the load is 0.5 m ⇒ d₁=0.5 m
The distance between the fulcrum and the force applied :
A load of 500N ⇒ F₁=500 N
The force applied :
Answer:
Explanation:
The cabinet does not move: this means that the net force acting on it is zero.
Along the horizontal direction, we have two forces:
- The push exerted by Bob, F = 200 N, forward
- The frictional force, , which acts in the opposite direction (backward)
Since the net force must be zero, we have:
So solving the equation we can find the magnitude of the friction force:
