Explanation:

Reasons for a high/low rate of Mortality: Science can be very invaluable determining the high/low rate of mortality in an area by conducting extensive research on various factors the people (of a society) are exposed to that causes the rate of mortality. In the case of high-rate of mortality, science can assist in providing guidelines in reducing the rate.

Epidemiology and Treatment of diseases: If there is a rise in the number of people affected by a particular disease in a society, science can help provide answers by determining if indeed the diseases are the same or just appear the same. Science can also assist in preventing and providing cure (treatment) to this disease.

Optimization and improved nutritive diet: Science assists in optimizing food products in order to get maximum benefits from the food eaten. A society might have some food substances that are not well stored or processed before eating; which could lead to loss of important nutrients, science can help correct this societal norm through research.

Answer from: Quest

Neptune is the eighth planet from the sun. it was the first planet to get its existence predicted by mathematical calculations before it was actually seen through a telescope on sept. 23, 1846. irregularities in the orbit of uranus led french astronomer alexis bouvard to suggest that the gravitational pull from another celestial body might be responsible. german astronomer johann galle then relied on subsequent calculations to spot neptune via telescope. previously, astronomer galileo galilei sketched the planet, but he mistook it for a star due to its slow motion. in accordance with all the other planets seen in the sky, this new world was given a name from greek and roman mythology — neptune, the roman god of the sea.

Answer from: Quest

Initial velocity, u = 4.9 m/sfinal velocity = v m/sinitial height, h₁ = 245 m final height, h₂ = 0a = -9.8 m/s²time taken = t secondss = ut + 0.5at²⇒ (h₂-h₁) = ut + 0.5at²⇒ 0-245 = 4.9t + 0.5×(-9.8)×t²⇒ -245 = 4.9t - 4.9t²⇒ 4.9t² -4.9t -245 =0solving it, we get t = 7.59sv = u + at = 4.9 -9.8×7.59 = 4.9 - 74.38 = -69.48 m/svelocity is 69.48 m/s downward
