Calculate the contact angle (in degrees) for olive oil if capillary action raises it to a height of 7.05 cm in a glass tube with a radius of 0.100 mm. O Is this value consistent with that for most organic liquids? No. The contact angle is nearest to the value for water-silver. Yes. The contact angle is nearest to the value for most organic liquids-glass. No. The contact angle is nearest to the value for kerosene-glass. No. The contact angle is nearest to the value for mercury-glass. 0000

A 16 cm diameter Styrofoam ball (p = 0.3 g/cm³) is released from the bottom of a tank filled with an unknown liquid. If the terminal speed of the ball is 1.66 m/s, what is the density of the liquid? The drag coefficient of the ball is 0.50. O 0.23 g/cm3 O 0.45 g/cm3 O 0.88 g/cm3 O 0.18 g/cm3
