Answer:
<h2>675 N</h2>
Explanation:
The work done by an object can be found by using the formula
workdone = force × distance
From the question we have
workdone = 45 × 15
We have the final answer as
<h3>675 N</h3>
Hope this helps you

Answer : The temperature of water is,
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.
where,
= specific heat of thermometer =
= specific heat of water =
= mass of thermometer = 33.0 g
= mass of water = 149 g
= final temperature =
= initial temperature of thermometer =
= initial temperature of water = ?
Now put all the given values in the above formula, we get:
Therefore, the temperature of water is,
