Answer:
If is constant, say k
Then,
∴ d ∝ w
Hence, weight is proportional to the density
Step-by-step explanation:
From the question,
Let w denote the weight of the rock in pounds
s denote the size of the rock in cubic inches and
d denote the density of the rock in pounds per cubic inch.
First, we will write the equation connecting w, s, and d.
We get
That is,
Now, given a 48-cubic-inch rock with weight w pounds, to show the proportional relation between the weight and the density, we will write
If is constant, say k
Then,
∴ d ∝ w
Hence, density is proportional to the weight OR weight is proportional to the density
Answer:
15 seconds
Step-by-step explanation:
Simply assume that total length to be covered be 'L'.
Now , of total length L is covered in time
.
We know distance traveled =speed×time
Let Object's velocity be V
Using this
Thus, velocity in terms of total length is
Now,
To cover total length L time needed is
Time taken =15 seconds
