To solve this problem you must apply the proccedure shown below:
1. You have that the following information given in the problem above: The<span> photograph is reduced by a scale factor of 3/8 and the original had a length of 20 inches,
2- Therefore you have:
length=20 inches-</span>(20 inches x 3/8)<span>
length=20 inches-7.5 inches
length=12.5 inches
3- Then, as you can see, the answer is: 12.5 inches.</span>
Answer:
Step-by-step explanation:
For this case we have the following value:
We can convert this first to 
like this:
Now we use the fact the the pressure is defined as 
, whre P is the pressure, F the force and A the area, so then 
and then we can replace this:
Now from definition of work we know that 
where W is the work, F the force and d the distance, so then is equivalent 
And if we replace this into the equation we got:
