A frog in a hemispherical pod just floats without sinking into a pond with density 1.35 g/cm^3. If the pod has radius 6 cm and negligible mass, what is the mass of the frog?

wouldn't one need the thickness of the pad? And what has the density given? The pond water, or the frog?

• physics (fluid mechanics: buoyant forces) -

Fg=Fb

m . g = d . V . g

m = d . V

m = (1,35 . 1000 kg per m cube) 2/3 pay ( .06 m )cube

m = 41 kg
