Answer

Explanation:

Step1: Recall scientific - notation form

Scientific notation is $a\times10^{n}$, where $1\leq|a|\lt10$ and $n$ is an integer.

Step2: Convert 0.0035 to scientific notation

Move the decimal point 3 places to the right to get a number between 1 and 10. So, $a = 3.5$. Since we moved the decimal point 3 places to the right, $n=-3$. The number 0.0035 in scientific notation is $3.5\times 10^{-3}$.

Answer:

C. $3.5\times 10^{-3}\text{ kg}$
