When devising a model, scientists can only use the information available during their lifetime. this means that the current model of the atom may be changed when new experiments are performed in the future. does this mean that the currently accepted model of the atom is useless? explain your answer.

no, it not useless. we still learn Bohr's model in HS n dats almost 200 yr old! while there may be new models, previous one is good for explaining the basics. it is also useful to learn previous model n see how our understanding improves over time.

The currently accepted model, when replaced by a new one, has served the purpose being the best model we have at this time. So it is far from useless. It provides a basis for the new model. Combined with all previous replaced models, they show the history and process of our understanding of the atom.

because it says use -2,0,and 2 for x, we can plug those numbers into the equation. y/4=3/4(-2)+2   y/4= -1 1/2 +2 now to get x by itself, we can multiply each side by 4. y=-6+8 which equals y=2 when x=-2. now you can do the same thing with 0 and 2 as x. you get y=8 when x=0 and y=14 when x=2.

x   |   y

-2 |   2

0   |   8

2   |   14

it is called kinetic energy
