2. Esther and Chris are trying to set physical boundaries for their relationship. Each person has slightly different ideas about what physical display of affection is
appropriate and what is not. Esther tells Chris that she feels uncomfortable
kissing him when they are alone in a dark area. Chris accepts her concerns and
promises to keep that particular display of affection in the "out of bounds"
category. (2 points)

Sally and sue were investigating the topic of friction in science. they used a small car and a ramp as seen in the picture to test what they were learning. they knew that they slipped easily on waxed floors but not on carpet, so they decided to change the material on the surface of the ramp to see what happened. they planned to use glass, carpet, aluminum foil, and sandpaper and run the car down the ramp over each surface. what would be the best research question to guide the girls' experiment? a) does the amount of surface area affect the friction on the moving car? b) will the car travel fastest on the glass surface? c) how does the angle of the ramp affect the speed of the car? d)do rougher surfaces tend to create more friction than smooth surfaces?
