a student sets up the following equation to convert a measurement. (the ? stands for a number the student is going to calculate.) fill in the missing part of this equation. $(20.\frac{n}{cm})cdotsquare = ?\frac{n}{mm}$
Answer
Explanation:
Step1: Recall length - unit conversion
We know that (1\ cm = 10\ mm), so (\frac{1}{cm}=\frac{10}{mm}).
Step2: Substitute the conversion factor
We have (\left(20.\frac{N}{cm}\right)\times\frac{1}{10}=\left(20.\frac{N}{cm}\right)\times\frac{1\ cm}{10\ mm}= 2.\frac{N}{mm}).
Answer:
(\frac{1}{10})
