Answer:
i think its secondary succession
Explanation:
because secondary succession happens when theirs an existing forest then its burnt down and a new ecosystem happens
Its because particles of air inside it are moving faster and making more pressure plus there is a pressure from the street.
Snell's law: n1Sinα=n2Sin β where α=Incidence angle, β=angle of refraction, n1 and n2 are the indices of refraction for water and air respectively.
Therefore,
Sinα=n2/n1 Sinβ For refracted ray to be along the surface of water, β=90° and thus Sinβ = 1
Sinα=n2/n1= 1/1.33 = 0.7519 => α=sin^-1 (0.7519) = 48.75°
When light moves from a medium of higher index of refraction (such as water) to medium of lesser index of refraction (such as air), the refracted ray is bend such that α is bigger than β. This is internal refraction. At some value of α, β approaches 90°. This incidence angle is called critical incidence angle. Therefore, the current scenario is shows critical angle of incidence.
Answer: Sometimes people try to use there flashlight but it doesnt turn on they take out there battierise and they rub them together. It doesnt work so they get new battiries
