Question

Which plot will give a straight line?

1) v vs. p
2) v vs. 1p
3) 1v vs. 1p
4) v vs. ln(p)

Answer 1

The plot that will give a straight line is v vs. 1/p.

Step-by-step explanation:

A straight line graph can be obtained when two variables are directly proportional to each other or inversely proportional to each other. In this case, if we plot the independent variable (x-axis) versus the dependent variable (y-axis) and the inverse square law is upheld, the plot will be a straight line.

Based on the given options:

1) v vs. p: This plot will not give a straight line as the variables are not directly or inversely proportional to each other.

2) v vs. 1/p: This plot will give a straight line as v and 1/p are inversely proportional to each other.

3) 1v vs. 1p: This plot will not give a straight line as the variables are not directly or inversely proportional to each other.

4) v vs. ln(p): This plot will not give a straight line as the variables are not directly or inversely proportional to each other.

Therefore, the correct answer is option 2) v vs. 1/p.
