Ahh help this is a science question I have: Will is learning about a new kind of plastic used to make tools. He learns that infrared light is absorbed by the plastic, x-ray light is transmitted through the plastic, and visible light is reflected off the plastic. Will wonders if the plastic will melt if he shines light on it.

Can light cause the plastic to melt? Why or why not? Does it matter what type of light he shines on the plastic?

Try b? sorry if i’m incorrect

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.
