Correct answer is in the range of 0.9-1.1 As we know that, volume is constant. Vi=Vf π/4(d12h1)= π/4(d22h2) d2=√d12(h1/h2) On substituting the values in the above equation, d2=√(0.5)2(1/0.25) d2= 1 m
Correct answer is in the range of 0.9-1.1
As we know that, volume is constant. Vi=Vf
π/4(d12h1)= π/4(d22h2)
d2=√d12(h1/h2)
On substituting the values in the above equation, d2=√(0.5)2(1/0.25)
d2= 1 m
