Got a question that I'm not quite sure how to approach:
"A force of 2500 N acting on the area of 120cm3 evokes a pressure of:"
This is all the info given in the question.
Divide the force in Newtons by the area in square METERS and you will have the pressure in Pascals. That is what they are looking for.
In your, case, the area is 0.120 m^2
Thank you drwls :)
To find the pressure in this scenario, you need to use the equation:
Pressure (P) = Force (F) / Area (A)
Given that the force is 2500 N and the area is 120 cm³, you should convert the given area from cm³ to m² as pressure is typically measured in pascal (Pa) or newtons per square meter (N/m²).
To do this, you need to remember that 1 m³ = 1,000,000 cm³.
So, divide the given area (120 cm³) by 1,000,000 to convert it to meters cubed (m³):
120 cm³ / 1,000,000 = 0.00012 m³
Now, you can substitute the values into the pressure equation:
P = F / A
P = 2500 N / 0.00012 m³
Divide the force by the area:
P = 2500 N / 0.00012 m³
P ≈ 20,833,333.33 N/m²
Therefore, the pressure evoked by the force of 2500 N acting on the area of 120 cm³ is approximately 20,833,333.33 N/m².
