Refer to the angle values given in the table below to answer the following questions. Enter a positive number for height if the water is raised above the surrounding water level, and a negative number if it is pushed below InterfaceContact Angle wateriglass water/paraffin 107 water/silver What height will water reach in a paraffin tube of the same radius? 0 Number cm 90" What height will water reach in a silver tube of the same radius? Number cm Previous Check Answer NextExit nt about us careers privacy policy terms of usExplanation / Answer
h= 2T cos theta/ (r pg)
7.45 x 10^-2 = ( 2T/ rpg) cos 0
(2T / rpg) = 7.45 x 10^-2
for praffin tube
h = 7.45 x 10^-2 cos 107 = -2.178 cm apprx
for silver tube
h = 7.45 x 10^-2 cos 90 = 0 cm
