Question

a force of 10kn acts on the surface of a liquid with an area of 0.08m2 what is the pressure​

Answer 1

Answer:

• Pressure exerted = 1250 KiloPascal

Explanation:

Given

• Force acting on surface, F = 10 kN
• Area of surface, A = 0.08 m²

To find

• Pressure applied, P =?

Formula required

• Formula to calculate Pressure

       Pressure = force / area

• Pressure is the force applied per unit area.
• SI unit of pressure = Pascal (Pa)
• 1 Pa = 1 N m⁻²
• Pressure is a scalar quantity.
• Dimensions of Pressure : [ M¹ L⁻¹ T⁻² ]

Solution

Given that,

→ Force applied, F = 10 kN

→ F = 10 × 1000 N

→ F = 10000 N

Using formula to calculate pressure

→ Pressure = Force / Area

→ P = F / A

→ P = (10000 N) / (0.08 m²)

→ P = 1250000 N m⁻²

→ P = 1250000 Pascal

→ P = 1250 kiloPascal

Therefore,

• A pressure of 1250 KiloPascal is exerted.

Answer 2

AnswEr :

• Force = 10 kN = 10000 N
• Area = 0.08 m²

Pressure : Pressure is defined as force applied per unit area. It's a tenser quantity. SI unit of pressure is Pascal's (behind the name of scientist who discovered this quantity)

$\longrightarrow \tt{Pressure\ =\ \dfrac{Force}{Area}} \\ \\ \\ \longrightarrow \tt{Pressure\ =\ \dfrac{10000}{0.08}} \\ \\ \\ \longrightarrow \underline{\boxed{\frak{Pressure\ =\ 125,000\ Pa}}}$
