The ratio of force acting perpendicular to the area, on which it acts is known as Force Friction Pressure Density
Answers
Answer:
pressure
Explanation:
Pressure = Thrust/Area
▶ Pressure is denoted by "P", thrust by "F" and area by "A".
▶ Thrust is the force acting perpendicularly on a surface.
▶ The S. I. unit of thrust is Newton.
▶ The S. I. unit of area is Square Metre.
▶ Overall, the S. I. unit of pressure is N/m²
▶ N/m² is also termed as "PASCAL".
▶ 1 Pascal = 1 Newton / 1 Square metre.
▶The atmospheric pressure however is generally expressed in "atm"unit.
▶ 1 atm = 1.013 × 10^5 Pascal.
▶ 1 atm = 76 cm of mercury column
______________________________
FACTORS AFFECTING PRESSURE :
______________________________
▶ Area of the surface on which the thrust acts.
▶ Magnitude of thrust acting on the surface.
Answer: b) Friction
Explanation:
Pressure = (Thrust/Area)
Pressure = "P", Thrust = "F" and Area = "A".
Thrust is the force acting perpendicularly on a surface.
The S. I. unit of thrust is Newton.
The S. I. unit of area is Square Metre.
Therefore, the S. I. unit of pressure is (N/m²)
(N/m²) is also named as "PASCAL".
1 Pascal = (1 Newton / 1 Square metre.)
