What is the minimum weight (in lbs) a bowling ball with diameter of 8.5 inches would need to have in order to sink in water (density of water is ~ 1.0 g/mL)? Assume that the volume of the bowling ball can be calculated as the volume of a sphere. Report your answer to the correct number of significant figures.

that would be because of both gravity and friction. so     c

when jerome paddle in flowing river towards east the net speed of jerome will increase

so the net speed of jerome will be given as

now the speed of paul will be same as it is given as he is running on the ground

so

so here we can say since the speed of jerome is more so he will win the race

now as we know the distance so the time difference is given as

so jerome will reach first and the time difference will be 203.55 s or 3.4 min
