Which type of waves is important to have for a surfer who wants to do aerial maneuvers? A. Plunging waves B. Surging waves C. Orbital waves D. Spilling waves

Answers

Plungingwaves is important to have for a surfer who wants to do aerial maneuvers.

The correct options is A.

What is a plunging wave?

When the ocean floor is steep or has abrupt depth changes, crashingwaves occur. They could be large close-outs or strong barrels. Combining pouring and plungingwaves creates a collapsing wave.

What causes plunging waves to form?

When the incoming surf strikes a steep ocean floor or a sea bottom with abrupt depth changes, plungingwaves are created. The wave's peak curves over and erupts on the trough as a result. A crashing sound is frequently audible due to the compression of the airbeneath the wave's lip.

#SPJ2

Aerial maneuvers in surfing demand taking the surfboard into the air. The best type of waves for such maneuvers are:

- the section of a wave coming towards you should be  smaller than the section you are on

- you should try to find closeout sections of waves (  formations that do not allow a tubular ride )

- the wave should be either wedging or bowling in towards you, it should not be a straight wave.

Which scientist first stated the relationship between buoyant force and weight of displaced fluid

Answers

Answer:

Archimedes

Explanation:

Archimedes suggested in his work, called On Floating Bodies that "Any object, totally or partially immersed in a fluid, is buoyed up by a force equal to the weight of the fluid displaced by the object." This was later known as the Archimedes principle.
He was Archimedes of Syracuse.
