The conversion used for the temperature from Kelvin to degree Celsius is:
where,
= temperature in Kelvin
= temperature in centigrade
As we are given the temperature in Kelvin is, 2.7
Now we have to determine the temperature in Kelvin.
Therefore, the temperature in degree Celsius is,
<u>Given:</u>
Diameter of a red blood cell = 0.000008
<u>To determine:</u>
The scientific notation corresponding to the given number
<u>Explanation:</u>
Scientific notation is a concise way of representing a very large or small number. It is written in two parts:
Given Number = Digits * Power of 10
In this case we have:
0.000008 = 8.0 * 10⁻⁶
