A large stone block is to be part of a harbour wall. The block is supported beneath the surface of the sea by a cable from a cra ne. Fig 2.1 shows the block with its top face a distance h beneath the surface of the sea.
2 answers:
Answer:
The top of the block has an area of 0.25m².
i) a Calculate the pressure on the top face of the block.
ii) The atmospheric pressure is 1.0 × 10⁵ Pa.
Calculate the pressure on the top face of the block due to the depth h of water.
iii) The density of sea water is 1020kg/m³.
Calculate the depth h.
Answer:
P=F/A, P is for pressure, F is for force, and A is for area, I can't really see half of the picture so I don't know the figures but just substitute them in and rearrange the equation if you have to. Good luck :))
