What are the 5 types of natural selection? Stabilizing selection, directional selection, diversifying selection, frequency -dependent selection, and sexual selection all contribute to the way natural selection can affect variation within a population. What is the rarest pattern of natural selection? The shape comes from the fact that both extremes are selected for during disruptive […]

How do you find acceleration without time?
How do you find acceleration without time? If the acceleration is constant, it is possible to find acceleration without time if we have the initial and final velocity of the object as well as the amount of displacement. The formula v2=u2+2as where v is the final velocity, u is the initial velocity, a is the […]

How does the angle of deviation depends on the refracting angle of the prism?
How does the angle of deviation depends on the refracting angle of the prism? The angle of deviation (δ) increases with the increase in the angle of prism (A). What is the angle of deviation when angle of incidence is 60? Answer. The angle of deviation will be 60° only. As refracted ray goes strainght […]
