2) The two solid blocks represented in the diagram are made of the same material and are under the same temperature and pressure conditions. If the mass of block X is 54 grams, what is the mass of block Y?

54 g

Explanation:

We'll begin by calculating the density of X. This can be obtained as follow:

Mass of X = 54 g

Length (L) = 9 cm

Breadth (B) = 2 cm

Height (H) = 1 cm

Volume of X = L × B × H

Volume of X = 9 × 2 × 1

Volume of X = 18 cm³

Density of X =?

Density = mass /volume

Density of X = 54/18

Density of X = 3 g/cm³

Finally, we shall determine the mass of Y as follow:

Length (L) = 3 cm

Breadth (B) = 3 cm

Height (H) = 2 cm

Volume of Y = L × B × H

Volume of Y = 3 × 3 × 2

Volume of Y = 18 cm³

Density of Y = Density of X (since they are made of the same material)

Density of X = 3 g/cm³

Density of Y = Density of X = 3 g/cm³

Mass of Y =.?

Density = mass /volume

3 = mass of Y /18

Cross multiply

Mass of Y = 3 × 18

Mass of Y = 54 g

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.
