An average ping pong ball has a radius of r=0.019m and an average density of p=84kg/m3. The density of air is p=1.225kg/m3.

a) what is the magnitude and direction in unit vector notation of the force required to hold it completely submerged in water?

b) while still completely submerged , what is the difference in pressure between the top and bottom of the ball?

C) if released, the ball will eventually find itself floating on the surface. What percent of the ball’s volume is below the surface of the water?

A floating ball has a density (P») of 600 kg/m' and has a radius (R) of 0.055 m. The equation that gives the depth (x) to which the ball is submerged under water with a density (Pw) of 1000 kg/m is given by:4 4/3*pi*R^3*pb*g=pi*x^2(R_x/3)*Pw*g where the gravitational acceleration g = 9.81 m/s. R a) Use the false-position method to find the depth x to which the ball is submerged under water within an interval [0, 0.1]? Conduct three iterations only...

You have a glass ball with a radius of 2.00 mm and a density of 2500 kg/m3. You hold the ball so it is fully submerged, just below the surface, in a tall cylinder full of glycerin, and then release the ball from rest. Take the viscosity of glycerin to be 1.5 Pa s and the density of glycerin to be 1250 kg/m3. Use g = 10 N/kg = 10 m/s2. Also, note that the drag force on a ball...
