Question

Please answer my following questions as fast as possible-
1 A hammer exerts a force of 1 5 N on each of the two nails A
and B The area of cross section of tip of nail A is
2mm² while that of a nail B is 6mm²
Calculate the pressure on each nail in Pascal
2 A vessel contains water up to height of 1 5m taking the
density of water 1000kg m-3,acceleration due to gravity
9 8 m s-2and area of the base vessel 100
cm2,calculate :(a) the pressure and (b) the thrust at
the base of vessel
3 The area of base of a cylindrical vessel is 300cm2
Water (density = 1000kgm-3) is poured into it up to a
depth of 6 cm Calculate: (a) the pressure, (b) the thrust of water
on the base (g = 10 ms-2)
4 (a) Calculate the height of the water coloumn which will exert
on its base the same pressure as the 70 cm column of mercury
Density of mercury is 13 6g cm-3
5 a simple u tube contains mercury to the same level in both of
its arms If water is poured to a height of 13 6 cm in one arm , how
much will be the rise in the mercury level in the other arm ?
Given : density of mercury = 13600 kg m-3 and the
density of water =1000 kg m-3
Please do it as early as possible

2)
Pressure is given by:P = hρgwhere h is the height or depth of
the liquidρ is the density of the liquidg = acceleration due to
gravity = 9 8 m/s2 = 980 cm/s2h = 1 5 mρ = 1000 kg/m3P = 1
5×1000×9 8 P = 14700 papressue = forceareathrust =
force= pressure×area = 14700×100×10-4= 147 N

3)
h = 6 cm = 0 06 mPressutre = p = hρgp = 0 06×1000×9

4) Height = 70 cm = 0 07 m
ρ = 13 6 g/cm3 = 13 6×103 kg/m3Pressure p = hρgp = 0
