A science lab, Cash mixes two clear liquids together in a beaker. Bubbles are produced, and a white solid forms and settles to the bottom. He plans to heat the beaker over low heat and make more observations. Which statement is most likely correct?

A physical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
A physical change occurred, so even if Cash heats it, the white solid will remain.
A chemical change occurred, so if Cash heats it, the white solid will dissolve to form the original mixture of clear liquids.
A chemical change occurred, so even if Cash heats it, the white solid will remain. four

Distance^2= yellow line ^2 (see picture) = 30^2 + 49^2so distance = squareroot of (300^2 +49^2)i dont know if this is how to solve it, but i cnt think of another way

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.

No because a circle or pie graph usually shows percentages you'd need a line graph
