Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below. A large black cross in a purple circle with a black line around the purple, with 10 small green balls dispersed within the purple circle.

What experimental evidence led to the development of this atomic model from the one before it?
A few of the positive particles aimed at a gold foil seemed to bounce back.
The colors of light emitted from heated atoms had very specific energies.
Equations were used to identify regions around the nucleus where electrons would likely be.
Cathode rays were bent in the same way whenever a magnet was brought near them.

step-by-step explanation:

given that there are two triangles j'k'l' and jkl>

the former is got by dilating the second one.

when drawn on a grid, (graph paper) coordinates of vertices of first triangle is

(6,12)j, (9,6)k and (12,9)l

side jk has length = distance between j and k

=

side j'k'=distance between j' and k'

=

ie j'k'l' has sides 1/3 of that of corresponding sides of jkl.

hence scale factor of 1/3 is used to get j'k'l'from jkl

for this case we have by definition, if two lines are perpendicular, then the product of their slopes is -1.

then, given the following line:

so,

we are looking for m_ {2}:

then, the line is given by:

we find "b" replacing the given point:

finally, the equation is:

option c

a
