    How Does Bubble Size Change with Depth in Fluid Mechanics?

    An air bubble originating from a deep-sea diver has a radius of 1.8 mm at the depth of the diver. When the bubble reaches the surface of the water, it has a radius of 2.6 mm. Assume that the temperature of the air in the bubble remains constant. The acceleration of gravity is 9.81 m/s^2. A)...

    Solve for Ratio of Steel Ax and Aluminum Piston Weights - Buoyancy Problem

    but if (76900)Vax = (249000)(769000Vax/24900) then wouldn't Vax get eliminated because the 249000s cross each other out?

    Solve for Ratio of Steel Ax and Aluminum Piston Weights - Buoyancy Problem

    Oh is Archimedes Principle the one that says that the buoyant force is equal to the weight of the fluid displaced?

    Solve for Ratio of Steel Ax and Aluminum Piston Weights - Buoyancy Problem

    Ok, so if (Pax)(Vax) - (Pw)(Vax) = (Pp)(Vp) - (Pw)(Vp) then (770000)Vax - (1000)Vax = (250000)Vp - (1000)Vp and (769000)Vax = (249000)Vp right? The only problem is that I don't know how to find the volume now.

    Solve for Ratio of Steel Ax and Aluminum Piston Weights - Buoyancy Problem

    [SOLVED] bouyancy problem Homework Statement If a steel ax and a aluminum piston have the same apparent weights in the water which can be written as (Pax)(Vax) - (Pw)(Vax) = (Pp)(Vp) - (Pw)(Vp) where P=rho(density), p=piston, V=volume, and w=water Find the ratio (Wax/Wp) of their weights...

    Solve Pelican's Initial Speed & Fish's Horizontal Distance

    help? I have this same problem for my honors physics class and I was wondering what equation you used to get vx = 9.4?
