Which statement best describes one way that spiral and elliptical galaxies typically differ? *

O Spiral galaxies are large, but elliptical galaxies are smaller.

O Spiral galaxies contain young stars, but elliptical galaxies contain mainly old stars.

Elliptical galaxies are held together by gravity, but spiral galaxies are held together by
centrifugal forces.

e/c, where e is its total energy

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
