Solution

The correct option is D parabolic
$P = P_{a t m} + ρ (10^{2}) \int_{0}^{2 r} x d x = P_{a t m} + \frac{ρ ω^{2} {(2 r)}^{2}}{2}$

$Δ P = \frac{ρ ω^{2} {(2 r)}^{2}}{2}$

$h = \frac{ω^{2} {(2 r)}^{2}}{2 ρ g} = \frac{{(\frac{2 π}{0.2})}^{2} {(0.2)}^{2}}{2 \times 10^{3} g}$

$h = 2 c m$

The liquid level in limbs ABC forms ______ shape. Fill in the blank.

The correct option is D parabolicP=Patm+ρ(102)∫2r0xdx=Patm+ρω2(2r)22ΔP=ρω2(2r)22h=ω2(2r)22ρg=(2π0.2)2(0.2)22×103g h=2 cm

The correct option is D parabolic
$P = P_{a t m} + ρ (10^{2}) \int_{0}^{2 r} x d x = P_{a t m} + \frac{ρ ω^{2} {(2 r)}^{2}}{2}$

$Δ P = \frac{ρ ω^{2} {(2 r)}^{2}}{2}$

$h = \frac{ω^{2} {(2 r)}^{2}}{2 ρ g} = \frac{{(\frac{2 π}{0.2})}^{2} {(0.2)}^{2}}{2 \times 10^{3} g}$

$h = 2 c m$
