By looking at the relative positions of the elements calcium, Ca, fluorine, F, sulfur, S, and oxygen, O, in the Periodic Table, which TWO descriptions are TRUE about calcium fluoride, CaF2, and sulfur dioxide, SO2?
the graph is tied to the reading here is the reading for the question students in a physics class observing the race note that each runner maintains the same acceleration from the start ofthe 8.0 second interval until they each reach the finish line where each of the runners slows to a stop. Two students inthe class make the following claims about the runners accelerations from the start of the 8.0 second interval until bothrunners are at rest.Student 1:Runner A has a positive acceleration until reaching the finish line and then a negative acceleration aftercrossing the finish line in order to undo all of the positive velocity she gained. Since Runner B neverhad any positive acceleration, she doesnt need any negative acceleration to slow to a stop; heracceleration will be zero the whole time.Student 2:But negative values mean away south in this case how could runner A be turning around? I think bothrunners must have positive accelerations the whole time since they are always moving north.For part (c), do not simple repeat the students arguments in your answers.here are the questions:i.Which aspects of student 1s reasoning, if any, are correct? Explain your answer.ii.Which aspects of student 1s reasoning, if any, are incorrect? Explain your answer.iii.Which aspects of student 2s reasoning, if any, are correct? Explain your answer.iv.Which aspects of student 2s reasoning, if any, are incorrect? Explain your answerTHANK YOU THANK YOU THANK YOU
