Question

One MPa is equivalent to one N/mm².
a) True
b) False

Answer 1

The statement that one MPa is equivalent to one N/mm² is true, as one megapascal equals one million pascals and there are 1,000,000 square millimeters in a square meter.

Step-by-step explanation:

The statement that one megapascal (MPa) is equivalent to one newton per square millimeter (N/mm²) is true. A pascal (Pa) is the SI unit for pressure and is defined as one newton (N) of force acting on an area of one square meter (m²). Consequently, one megapascal is one million pascals, or 1 MPa = 1,000,000 N/m². Since there are 1,000,000 square millimeters in a square meter, converting N/m² to N/mm² gives us 1 MPa = 1 N/mm².
