39. Folding paper. Each time you fold an ordinary sheet of paper in half, you double the thickness.
a. A single sheet of 20-pound bond paper is about a tenth of a millimeter
thick. How would you come up with this estimate? (Hint: Paper often
comes in reams of 500 pages.)
b. Find an exponential formula that gives the thickness of the sheet of paper
in part a after
f
folds in millimeters and in kilometers.
c. What would be the thickness in kilometers if you were physically able to
fold it 50 times? Note: For comparison, the distance from Earth to the Sun
is about
149,600,000
kilometers.

62.5 paisa

step-by-step explanation:

4000*70 = 280000

280000-(2000*90) = 100000

4000-2400 = 1600

100000/1600 = 62.5

step-by-step explanation:

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 !
