Pressure in fluids

What is the strength of the gravitational field strength on Earth?

• 7 m/s2

• 10 M/s2

• 5 m/s2

• 15 m/s2

What does the symbol p represent in our equation for pressure

• Pressure

• Density

• Gravitational field strength

• Party

What is the density of water.

• 1000 Kg/m3

• 1 Kg/m3

• 10 Kg/m3

• Zero

What is the pressure from water exerted on an object at a depth of 9 m?

Pressure = Density x Gravitational field strength x height

• 900 Pa

• 90,000 Pa

• 150 Pa

• 200 Pa

Calculate the pressure on an object at a depth of 11m in water.

• 11,000 Pa

• 15 Pa

• 110 Pa

• 110,000 Pa

An object experiences a pressure of 11000 Pa when placed in water. How deep is it?

Height = Pressure / (Density x Gravitational field strength)

• 1.1 m

• 110 m

• 15 m

• 44 m

Simon doubles the density of the fluid an object has been placed in. What impact would this have on the pressure?

• It would double

• It would triple

• No change

• It would half.

An object has been placed 15 metres inside some olive oils. It experiences a pressure of 21000Pa. What is the density of olive oil?

• 17 Kg/m3

• 14 Kg/m3

• 140 Kg/m3

• 1400 Kg/m3

How would doubling the strength of the gravitational field strength impact the pressure an object experiences?

• No change

• Double the pressure

• Half the pressure

• Quadruple the pressure.
