← What is the excess pressure inside an air bubble of radius 0.10 mm just under the surface of water? (Surface tension 0.072 N/m.)A cotton wick acts like a bundle of fine tubes. In one such tube of radius 0.20 mm, dipping into lamp kerosene (surface tension 0.025 N/m, density 800 kg/m³, angle of contact 0°), how far up does the kerosene climb? (g = 9.8 m/s².) →
