Doubling an object’s height will have what effect on its potential energy due to gravity?

doubled

Explanation:

The energy possessed by the virtue of position or configuration of the body is called potential energy of the body.

The formula for the potential energy is given by

P.E = m g h

Where, m be the mass of the body, g be the acceleration due to gravity and h be the height.

So, if the height is doubled, the potential energy is also doubled.

the answer would be   dignified - apex

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
