14 m/s because Vf^2=Vi^2 + 2a(delta x).
Her acceleration is 10 m/s^2.
So 0^2 + 2(10)(10) = 200
sqrt 200 = 14.1421 so with sf's the answer is 14
When light enters a different medium, its speed changes as it undergoes refraction. Refraction is the bending of light as it passes from one medium to another, due to the change in speed.
When speed passes from one medium to another, it can change because the speed of a wave is determined by the medium's properties. If the wave enters a medium where its speed is higher, it will speed up. If it enters a medium with a lower speed, it will slow down. This change in speed can also cause the wave to refract or change direction.
Slows IF it enters the water from air (and not - say - glass).
No, a light wave will not refract if it enters a new medium perpendicular to the surface. This is because refraction occurs when light enters a new medium at an angle, causing it to change speed and direction. When light enters perpendicular to the surface, there is no change in speed or direction, so refraction does not occur.
The speed of light changes as it enters a different medium due to the change in the medium's optical properties. This change causes light to either speed up or slow down depending on the medium's refractive index. The change in speed results in the phenomenon of refraction.

It increases.
The speed of the dives are not measured as part of the event.
from high speed dives into the ocean for fish
Get your speed to 75.
That would depend what it enters from. If the light is transitioning from air to water,its speed decreases. If it's going from jello to water, its speed increases.
