An air bubble, released 2.5 metres underwater, has as diameter of 7.7 $\mathrm{mm}$ when released. Assume the water and air bubble to be at the same temperature of $13^{?}\mathrm{C}$, and the atmosphere's pressure at the water surface is 1 bar. a. The absolute pressure in the water at the depth where the bubble is released is $\mathrm{kPa}$. b. The gauge pressure of the air inside the bubble immediately after it is released is $\mathrm{kPa}$. c. The mass of the air inside the bubble is milligrams. d. The magnitude of the bouyancy force on the bubble is $\mathrm{mN}$. e. The bouyancy force on the bubble is times more than the weight of the bubble.
