Answer: D. It can be conducted with existing data
Explanation:
Cohort studies observe a number of people over a period of time to discover the factors pertaining to a disease such as its causes and effects. It can be prospective, which uses data gathered in the future or retrospective which uses data already collected.
Prospective cohort studies are useful in estimating risk and impractical for studying rare diseases due to the need for a large group. When used to identify the cause of a disease, a hypothesis is tested by monitoring a cohort for any differences in health associated with the risk factor
.
Existing data. and the study of diseases with a long latency between exposure and symptoms development apply to retrospective cohort study.
Answer:
B) You will bask in your friend's reflected glory and congratulate him or her on winning the free throw contest.

In his book “Guns, Germs and Steel,” Jared Diamond argues that societies that have prevailed and conquered others (for example, Eurasian societies) have been lucky in terms of environment. This has allowed them to enjoy advantages and adaptations that other cultures have not had. When he discusses the case of Papua New Guinea, he gives several reasons for the lack of technological development they had before the arrival of Europeans:
Lack of large mammals that could be of help in transportation or agriculture.
Isolation from other major cultures.
Lack of domesticable animals.
Lack of domesticable crops.
Enormous natural barriers that prevented constant contact between various cultural groups.
Answer:
Option C
Explanation:
Let the potential energy of rock A be represented as Pa
And the potential energy of rock B be represented as Pb
Pa = ma * g * h
Pb = mb * g*h
ma = 2 * mb
Thus, Pa = 2 mb * g*h
Pa/Pb = 2 mb * g*h/mb * g*h
Pa/Pb = 2
Pa = 2 * Pb
The energy pf rock A is two times the energy of rock B.
OR
Pb = Pa/2
Hence, option C is correct
