Question

$\sf{\underline {Refer\:the\:attached\:picture}}$ ​

Answer 1

height of the spirit column

h1 =12.5cm = 0.125

Height of the water column

h2 = 10cm =0.1m

p0 = Patm

P1 density of spirit

p2 density of water

Now pb =pd

= p0 + h1p1g = p0+h2p2g

= P1/p2= h2/h1= 0.8

put the value and get

specific gravity of spirit =0.8
