A hypothetical “ice geode” is formed by a bubble of air around which the water has frozen, imprisoning the air itself. The geode is spherical and the air bubble inside is also spherical, sharing the same centre as in figure. a) The geode is at temperature Tg=0°C with a diameter dg=5cm and it is immersed in water at 0 °C too, Calculate the radius of the air bubble inside the geode, so that the geode would float.

You are about to open a container of soy milk but notice that there are instructions to “shake well before serving.” the soy milk is most likely a

Sawyer is studying diffraction. he draws a diagram of a plane wave to show how light waves travel. which best describes sawyer’s error? the wave fronts should be perpendicular to the direction in which the waves move. the arrow showing the direction of movement of the waves should be pointing to the left. the arrow showing the direction of movement of the waves should be pointing downward. the wave fronts should be both parallel and perpendicular to the direction in which the waves move.
