Physics

A bathysphere used for deep-sea exploration has a radius of 1.52m and a mass of 1.16 âœ• 104 kg. To dive, this submarine takes onmass in the form of sea water. Determine the amount of mass thatthe submarine must take on if it is to descend at a constant speedof 1.40 m/s, when the resistive force on it is 1101 N in the upwarddirection. The density of seawater is 1.03 âœ• 103 kg/m3.
Also, A horizontalpipe 20.00 cm in diameter has a smooth reduction to a pipe 10.00 cmin diameter. If the pressure of the water in the larger pipe is7.50 104 Pa and the pressure in the smaller pipe is 6.00 104 Pa, atwhat rate does water flow through the pipes?
