Lake Ray was once home to thousands of walleye fish. But soil runoff from a nearby golf course in the 1980s made the water almost uninhabitable for the fish, and reduced their numbers to almost zero. This image is courtesy of Fond du Lac County, WI In recent years the golf course has been relocated, and efforts have been made to clean up the effects of runoff to return Lake Ray to its original conditions. This was done so that the walleye's numbers might increase. This sort of effort is known as A. habitat restoration B. reforestation C. repopulation D. spear fishing

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards

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
