That's called "refraction".
Answer:
As evolutionary biologists have shown, this multicellularity was linked to the rise in oxygen and thus played a significant role for life on Earth as it is today. ... By producing oxygen and evolving into multicellular forms, they played a key role in the emergence of organisms that breathe oxygen.
Explanation:
Velocity is a function of time and defined by both a magnitude and a direction. Often in physics problems, you will need to calculate the initial velocity (speed and direction) at which an object in question began to travel. There are multiple equations that can be used to determine initial velocity. Using the information given in a problem, you can determine the proper equation to use and easily answer your question.

Answer:
Part a)
Part b)
Part c)
Explanation:
Part a)
The height of the diving board is given as
now the speed of the diver is given as
when the diver will jump into the water then his displacement in vertical direction is same as that of height of diving board
So we will have
Part b)
plug in the values in the above equation
Part c)
Horizontal distance moved by the diver is given as
so the distance from the edge of the pool is given as
Answer:
1
Explanation:
Specific gravity is a ratio (of 2 densities) so it has no unit.
