Answer» Answer: ye neche sara explain krdia brainlist me add KRDO... Explanation: ANSWER Given : ρ oil =0.8 ρ water =1 When water goes down by x amount in one SIDE of U-tube,then it moves up by x amount in other tube. Thus the total DIFFERENCE in height of water in both side is EQUAL to 2x. ∴ The difference in height of water =2(25)=50cm Using P A =P B
∴ P o +ρ oil gh=P o +ρ water g(50) Or (0.8)gh=(1)g(50) ⟹h=62.5cm Thus the oil stands higher tahn water by amount Δh=h−50=62.5−50=12.5cm |
