(adsbygoogle = window.adsbygoogle || []).push({}); 1. A bubble of air of volume v forms at the bottom of a container of fluid (neglect effects of viscosity). Let H be the height of the fluid, and let ρf and ρa denote densities of fluid

and air respectively. How fast is the bubble moving when it reaches the surface?

2. What is the work performed by the buoyant force on the bubble from the moment it

forms on the bottom until it reaches surface?

2. v=vo+at, F=ma, Fb=pvg

3. I have no clue how to solve this. Im assuming it has to do with the equation P(h)= P(O) +pgH and maybe kinematics? For part b i used Fb=pv(of air)g and multiplied it times H so work=pvgH Thanks
