An undersea research chamber is spherical with an external diameter of 5.50m . the mass of the chamber, when occupied, is 88300kg . it is anchored to the sea bottom by a cable. the density of seawater is 1025 kg/m3.a. what is the buoyant force on the chamber? express your answer to three significant figures and include the appropriate units. b. what is the tension in the cable? express your answer to two significant figures and include the appropriate units.

d. air pressure decreases as altitude increases.

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

god i hope this !
