A stone is dropped into a lake. Calculate the increase in pressure on the stone caused by the water when it sinks from 1 m deep to 6 m deep.
(The density of water is 1,000 kg/m3 and gravitational field strength is 10 N/kg).
(a)
A 3 metre tall container is sealed and half-filled with fluid. The density of the fluid is ρ=1.5 kg/m3. What is the pressure at the bottom of the container?
(a)
A container is sealed and the pressure at the bottom is measured as 22.5 Pa. The density of the fluid is ρ=1.5 kg/m3. What is the height of the container?
(a)
An astronaut is exploring a methane lake on an alien world. Her barometer reports a fluid pressure of 4.5 kPa. If the density of methane is 0.657 kg/m3 and she is swimming 12 metres below the surface, calculate the gravitational constant of this planet.
Give your answer to 3 significant figures.
(a)
An astronaut is exploring a methane lake on an alien world. Her barometer reports a fluid pressure of 4.5 kPa. If the density of methane is 0.657 kg/m3 and the gravitational constant of the exoplanet is 570.77 m/s2, calculate the depth of the astronaut.
(a)
The pressure experienced by a diver is 380,000 Pa. If the density of water is 1000 kg/m3, calculate the depth of this diver.
(a)
A diver is swimming at a depth of 38 metres. If the density of water is 1000 kg/m3, calculate the pressure acting on this diver.
(a)
A tool is placed in ethanol to sterilise it. If the container is 30 cm tall and the density of ethanol is 789 kg/m3, calculate the pressure experienced by the tool.
(a)
A tool is placed in ethanol to sterilise it. If the pressure acting on the object is 2.367 kPa and the density of ethanol is 789 kg/m3, calculate the depth of the container.
(a)
The pressure on a diver is 25 kPa. He descends further to a depth of 40 m and the pressure increases to 400 kPa. Calculate his original depth.
