As the metal expands as does the road bed so neither really effevts those foing over the bridge. as it is hot the metal will expand and so will most tarmac on roads.
Answer:
Explanation:
Gauge pressure at the bottom of the cylinder depends on the height of water in the cylinder
So here we can say that
now when liquid is filled to height "h" in base area "A" then gauge pressure of the liquid at the bottom is given as
now we put the whole liquid into another cylinder with twice radius of the first cylinder
So area becomes 4 times
now by volume conservation we can say that if area is increased by 4 times then height of liquid will decrease by 4 times
so we have
so gauge pressure is given as
