Atennis ball has a rebound percentage of 60%. if it is initially dropped from a height of 20 feet, how high will it bounce on the second bounce

The ball will bounce 12 feet on the second bounce

Step-by-step explanation:

You can find this simply by using multiplication, the initial drop is 20 and the ball has 60% rebound. You can easily remember how to figure out these kind of problems by remembering this rule. Ask yourself, What is 60% OF 20? And anytime that you see "of" in math it means multiplication, so 60% as a decimal would be 0.6. And with the equation 0.6*20=12 you find the answer    

the population of other specie of birds will decline or other specie of birds will find some alternate source of food to survive.

explanation:

according to the competitive exclusion principle, which is also known as gause's law, two specie living in the same niche and feeding on the same resource cannot co-exist stably.

as we have well studied the theory of natural selection which states that only those organisms survive which have better tendency to compete for food and adapt to the environmental conditions.

coming towards the question, what wi ll happen when one species outcompetes the other for the small fish , the other specie will not get enough food and will start to die or decline in population. eventually either other specie needs to find another alternative food source for itself or migrate at some other location where there is less competition otherwise it will just not exist anymore at that niche.

hope it !
