Answer 1

The correct answer is Newton per metre squared N/m²

Key Points

One Pascal (Pa) is defined as one Newton of force applied over an area of one square meter.
It is a derived unit of pressure used in the International System of Units (SI).
The formula for pressure (P) is given by P = F/A, where F is the force applied perpendicular to the surface (in Newtons) and A is the area over which the force is distributed (in square meters).
Thus, 1 Pa = 1 N/m².

Additional Information

The Pascal is named after Blaise Pascal, a French mathematician, physicist, and inventor.
It is commonly used to measure internal pressure, stress, Young's modulus, and tensile strength.
Other units of pressure include the bar, atmosphere (atm), and torr, but the Pascal is the standard SI unit.
1 bar = 100,000 Pa, 1 atm ≈ 101,325 Pa, and 1 torr ≈ 133.322 Pa.
