A scientist studies the effect of adding different amounts of salt on the boiling point of water. He places his results in the graph below. What are the independent and dependent variables in this experiment?

James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses, shapes, and sizes from point a to point b. the objects are a toy car, a car, a refrigerator, and a kitchen table. after some experimentation, he finds that force is dependent on the mass of the object, rather than it's size or shape. the object that takes the most force to move is the
