Where would you find the largest pressure?

• At the bottom of the ocean

• At the top of Mt Everest

• Close to ground on the Scotch oval

• In a rockpool on the Great Barrier Reef

Convert 10 kg to Newtons

• 0.098 N

• 4.5 N

• 100 N

• 98 N

The pressure resulting from a force of 50 N exerted over an area of 5 m² is

• 10 N

• 0.1 N

• 10 N/m2

• 0.1 Pa

If a pressure of 100N/m² is applied to a piston with an area of 1.5m² what is the total force?

• 150N

• 75m²

• 0.015N

• 50N
