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:
Answer:
Step-by-step explanation:
The missing figure is attached.
The perimeter of a rectangle is:
Where "l" is the lenght and "w" is the width.
You can identify in the figure that:
Then, knowing the perimeter of the rectangle, you can make the subsitution into the formula:
Now you must simplify and solve for "z"
Finally, substituting the value of "z" into , you get:
