Answers

Answer 1

If the density of the mattress is 1000 kg/m³. Then the mass of the mattress will be 4800 kg.

What is density?

Density is defined as the mass per unit volume. It is an important parameter in order to understand the fluid and its properties. Its unit is kg/m³.

The mass and density relation is given as

mass = density × volume

The mattress of a water bed is 4.00 m long by 4.00 m wide and 30.0 cm deep. And the density of the mattress is 1000 kg/m³.

Then the mass of the mattress will be

M = 1000 x 4 x 4 x 0.3

M = 4800 kg

Answers

The line from the poem that leaves readers wondering what makes the speaker realize he should have appreciated his father more is: "What did I know, what did I know."

What is the meaning of the line in the poem?

Before we get to lines quoted from the poem here, we see that the speaker talks about how his father took the pain to drive the cold away from the house and polish his shoes.

Now, when he woke up, he spoke to him indifferently. Thereafter, he asked the question given to show that he did not know what he was doing at that particular time.
