Answer:
3750 square millimeters (mm^2)
Explanation:
Parameters given:
Force = 15 Newtons (N)
Pressure = 4000 Pascals (Pa)
Convert from Pascals to Newton per millimeters square (N/mm^2)
1 Pa= 1 Newton per meters square (N/m^2)
Therefore,
1 Pa = 1 × 10^-6 Newton per millimeters square
Hence,
4000 Pa will be equals to
(4000 × 1 × 10^-6) N/mm^2 = 0.004N/mm^2
From
Pressure = Force / Area
Area = Force / Pressure
Area = 15(N) ÷ 0.004 (N/mm^2)
Area = 3750 square millimeters (mm^2)
Hence, the area of the surface in units of square milimeters is 3750mm^2
Answer:
The answer to the question is;
The area of the surface in units of square millimeters [mm²] is 3750 mm².
Explanation:
Here, it is necessary to note that the formula for pressure = Force/Area
Therefore the area is given by
Area = Force/Pressure
Where the force = 15 Newtons (N) and
The pressure = 4000 Pascals (Pa)
Then we have
Area = 15 N ÷ 4000 Pa = 0.00375 m²
Converting the area into mm² we have
1 m² = 1000000 mm² therefore
0.00375 m² = 1000000×0.00375 mm² = 3750 mm²
