Question Calculate the pressure exerted on a surface by a brick of weight 10 N. The area in contact with the surface is 20 cm2

Answer: 5000 Explanation: pressure: force / area SI unit of force: newton SI unit of area: metre² Force exerted: 10 N Area on which it is exerted : 20 cm² Since area has to be in m² , we convert cm² to m² by dividing it by 10000( m:100cm, 1m²: 10000 cm²) Area=20/10000: 0.002 m² So, pressure= 10/0.002=5000 pa( SI unit of pressure is pascal) Log in to Reply

Answer: Explanation: Force of brick = 10 N Area of surface = 20 cm^2 Pressure = force / area ∴ Pressure = 10 / 20 = 1 / 2 or 0.5 Pa Hope this hepls plz mark it as brainliest!!!!!!!! Log in to Reply

Answer: 5000

Explanation: pressure: force / area

SI unit of force: newton

SI unit of area: metre²

Force exerted: 10 N

Area on which it is exerted : 20 cm²

Since area has to be in m² , we convert cm² to m² by dividing it by 10000( m:100cm, 1m²: 10000 cm²)

Area=20/10000: 0.002 m²

So, pressure= 10/0.002=5000 pa( SI unit of pressure is pascal)

Answer:Explanation:Force of brick = 10 N

Area of surface = 20 cm^2

Pressure = force / area

∴ Pressure = 10 / 20

=

1 / 2 or 0.5 PaHope this hepls
