If the plum pudding model of the atom was correct, what should the results of Rutherford’s experiment be? Most of the positively charged particles should bounce back at a range of angles as they collide with the atoms in the foil; only a few should pass straight through the foil.

Most of the positively charged particles should pass straight through the foil because they move easily through the positively charged matter in the gold atoms.

Most of the positively charged particles should collide with the foil and stay there because they stick to the negatively charged gold atoms.

Explanation:

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.
