In the figures below, identical boxes of mass 10kg are moving to the right on a flat surface. The same magnitude (amount) of force, F, is applied to each box for the distance, d, indicated in the figures. Rank
these situations in order of the work done on the box by F while the box
is moving the indicated distance to the right. In this case, direction is
important. Explain your reasoning. *
*

A. A=B > C > D=F > E
B. B=D > A=C=E=F
C. B > A=E > C > D=F
D. All the same
E. All zero
F. Cannot determine

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

float.

archimedes' principle

denser than water sinks in water.

denser than mercury would sink in it

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
