Expert Solution

Introduction:

Disclaimer: “Since you have asked multiple question, we will solve the first question for you. If you

want any specific question to be solved then please specify the question number or post

only that question.”

We are given several quantities in the question. We first convert these into scientific notations.

The scientific notation is given as

$S N = k \times 10^{n}$

Here $k$ should not have more that 1 digit to the left of decimal and $n$ is integer. We hence convert to scientific notation. We then find number of significant figures in it.
