Question

question 18 (3 points)
the slope for the straight line is numerically 1 and the units are 2.
a. 0.00 b. 0.40 c. 0.50 d. 1.0 e. 2.0 f. 2.5 g. 5.0
h. ms i. μm j. ms/μm k. μm/ms l. no units

Explanation:

Step1: Select two points

Let's take two points on the line: (0, 0) and (100, 200).

Step2: Calculate the slope

The slope formula is $m=\frac{y_2 - y_1}{x_2 - x_1}$. Here, $x_1 = 0,y_1 = 0,x_2=100,y_2 = 200$. So $m=\frac{200 - 0}{100 - 0}=2.0$.

Step3: Determine the units

The $y$-axis is in $\mu m$ and the $x$-axis is in $Ms$. The units of slope are $\frac{\text{units of }y}{\text{units of }x}$, so the units are $\mu m/Ms$.

Answer:

E. 2.0
K. $\mu m/Ms$
