At which position would a cat on Earth have least amount of pull due to gravity? in a cat bed on the ground

on a second floor window sill

in a plane flying above Earth

in a plane flying above Earth

Explanation:

Gravity is the force that draws  objects toward center of the earth. If you throw an object up on the earth's surface, you will notice that it will fall back to the ground due to the earth's gravitational pull on the object.

However, the further one goes from the earth's surface, the lesser the gravitational pull. Therefore the cat will experience less gravitational pull in an airplane flying at a higher altitude.

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

one "light year" is the distance that light travels, through vacuum, in one julian year.   that's 365.25 days, of 24 hours each.
