______ liters/s B. A hollow sphere made of leadfloats half submerged in water. Find the ratio of the thickness ofthe lead to the outer radius of thesphere. ___________

Explanation / Answer

Radius r= 1.07 cm =0.0107 m

Area A = (pi) r ^ 2

            = 3.596 * 10 ^ -4 m ^ 2

Speed v = 5.31 m / s

Flow rate V = A v

                    = 1.909 * 10 ^ -3 m ^ 3/ s

                    = 1.909 Li / s   Since 1 L = 10 ^ -3 m^ 3
