Average acceleration is the ratio of the change in velocity to the time it takes for that change to occur:
We want to find 
:
From Simple Harmonic Motion (SHM), the restoring force is given by:
F = -ω²x
We can see that restoring force is proportional to the displacement, x. So if the displacement x is doubled, then the restoring force will also be doubled.
<span>The energy released by an earthquake occurs
in the form of either volcanic eruptions or better yet, seismic waves. There is
no radiation in earthquake except if it destroys nuclear power plants.
Earthquakes are also the reason why long ago, there is a continental drift long
ago wherein <span>seismic,
volcanic, and geothermal activity are found along imagined plate boundaries, the
plates were actually rubbing against
each other as evidence is seen on the formed mountain ranges And there is paleomagnetism,
magnetic field placement in the layers of the rock are present.</span></span>
Answer:
Explanation:
in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves in deep water travel faster than in shallow.from one medium to another or from a gradual change in the medium. Refraction of light is the most commonly observed phenomenon, but other waves such as sound waves and water waves also experience refraction in other words it can be all of them or i can narrow it down some more it can have a change in dirction when light enters into a traveling point for example after moving through air it passes through a prism called compare reflection
