Running up a tree after running straight is a change in direction thus, although the speed is same 30mph, the velocity is different. Now, in choice B, the cat is slowing down after having escaped from the dog. This is also a change in velocity (because the speed decreases).When the cat is sitting still the whole time, its velocity is 0.0mph the entire time. That means the velocity doesn't change <span>And when the cat is running around the house, the cat is changing direction (thus velocity is different).
(This is relevantly a circular motion, and acceleration is a non-zero constant, and thus veloicty of course isn't same).</span>
The answer is <span>the number of DNA mutations in an organism is measured over time to determine how long it will take for a new species to evolve.</span>
Answer:
D.Subduction zones are near plate boundaries
Explanation:
Subduction zones are plate boundaries where two plates meet ,one plate is thrust beneath the other.Due to this earthquakes and Volcanic eruptions occurred. this geohazard affects millions of people around the globe, specifically at edge of the Pacific Ocean.This edges consists of many subduction zones. Megathrust is the largest earthquake occurred at the interface between the boundaries of the two plates.
