The problem tell us that the temperature as function of time in downtown mathville is given by:
The average temperature over a given interval can be calculated as:
Where:
So, the initial temperature in this case, would be the temperature at noon, and the final temperature would be the temperature at midnight:
Therefore:
Hence, the average temperature between noon and midnight is:
Answer:
<h3>The answer is 2.67 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of iron = 8 g
volume = final volume of water - initial volume of water
volume = 49 - 46 = 3 mL
We have
We have the final answer as
<h3>2.67 g/mL</h3>
Hope this helps you
