Pressure is equal to force per unit area. P=F/A therefore F=PA A brick has the following dimensions, 1.00 mx 0.200 m x 0.500 m. The pressure exerted
by the brick on the floor is different when the brick is placed in different ways. If the
minimum pressure exerted by the brick on the floor is 100.0 Pa, what is the force
exerted on the floor in newtons (N)?
O 200. N
0 50.0 N
O 10.0 N
O 100, N

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.
