The small piston of the hydraulic press with an area of 20 cm² is subjected to a force of 200 N and has lowered by 50 cm. What force acts on a large piston with an area of 0.01 m² and to what height did it rise? (I already found out that large piston force is 1000N how do I calculate in what height did it rise?)

what was the answer?

as we know our atmosphere or air have different levels. every level has other gasses, and every gas has another permeability. when the light comes from lower permeability to higher permeability, it changes its direction. so that means that when the light comes from the moon to the earth, it changes it's direction many more times. it basically means that the shape of the light part of the moon is changed on the earth.

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
