The experimental setup shown in the picture has a fixed ramp and an adjustable ramp. Students roll a ball down the fixed ramp and measure how far up the adjustable ramp the ball travels. During the experiment, they change the slope of the adjustable ramp and record their data in the table.

The students concluded that the lower the slope of the adjustable ramp, the greater the distance the ball continued to roll. What other conclusion can also be drawn from the findings?
A) The ball stops because there is some force acting on it.
B) The only force acting on the ball during its journey is gravity.
C) The ball stops eventually because there is no force acting on it.
D) The slope of the ramp has no role to play in the stopping of the ball.

The last few miles of the marathon are the most difficult for heather, her hair plastered to her head, sweat clinging to her arms, and her legs already feeling as if they had nothing left, just dead weight. after grabbing a cup of ice water, she feels the ice cubes smash against her nose as she gulps some cool refreshment and keeps on running. in these last few miles, the breeze kicks up and she finally feels some coolness against her skin. drips of sweat, once clinging to her forehead, now spill down, and heather feels more pain as the sweat flows into her eyes.which of the following is the most likely reason why the ice struck heather’s nose when she took a drink? a) water can function as a solvent. b) water can store large amounts of heat. c) water can moderate temperatures through evaporative cooling. d) the density of water decreases when it freezes. e) water has a cohesive nature.sweat remained on heather’s forehead and arms because of the a) high salt content of sweat b) cohesive nature of water c) ability of water to moderate heat d) high evaporative cooling effect of water e) ability of water to act as a solvent
