During which time interval was the motion fastest?

Answer : The correct option is, 1 hr to 2 hr

Explanation :

Velocity : Velocity is defined as the rate of change of position of an object with respect to the time. It is a vector quantity that means it tell us about the magnitude and direction of an object.

Formula used :

To calculate the velocity for time interval 0 to 2 hr:

To calculate the velocity for time interval 2 to 4 hr:

To calculate the velocity for time interval 4 to 5 hr:

From this we conclude that, at time interval 0 to 2 hr the motion will be fastest.

Hence, the correct option is, 1 hr to 2 hr

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.
