ASAP Which of the following items have the WEAKEST gravitational force?
(3 Points)

a)A pencil and a book that are 10 cm apart

b)A pencil and a book that are 20 cm apart

c)A bowling ball and a book that are 10 cm apart

d)A bowling ball and a book that are 20 cm apart

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
