Answer:
light, which normally travels the 240,000 miles from the Moon to Earth in less than two seconds, has been slowed to the speed of a minivan in rush-hour traffic — 38 miles an hour.
An entirely new state of matter, first observed four years ago, has made this possible. When atoms become packed super-closely together at super-low temperatures and super-high vacuum, they lose their identity as individual particles and act like a single super-
atom with characteristics similar to a laser.

Answer:
divide 2000 by however many children
Answer:
1. 3/2
2. 4
Step-by-step explanation:
The coordinates of x are (1.6, 1.2).
Solution:
Given points of the line segment are A(0, 0) and B(4, 3)
X be the point divided the line segment AB in the distance
.
i.e., in the ratio of 2 : 3.
Section formula:
![$P(x, y)=\left(\frac{m x_{2}+nx_{1}}{m+n}, \frac{my_{2}+n y_{1}}{m+n}\right)](https://tex.z-dn.net/?f=%24P%28x%2C%20y%29%3D%5Cleft%28%5Cfrac%7Bm%20x_%7B2%7D%2Bnx_%7B1%7D%7D%7Bm%2Bn%7D%2C%20%5Cfrac%7Bmy_%7B2%7D%2Bn%20y_%7B1%7D%7D%7Bm%2Bn%7D%5Cright%29)
Here,
and m = 2, n = 3
Substitute these in the section formula,
![$X(x, y)=\left(\frac{2\times4+3\times0}{2+3}, \frac{2\times3+3\times0}{2+3}\right)](https://tex.z-dn.net/?f=%24X%28x%2C%20y%29%3D%5Cleft%28%5Cfrac%7B2%5Ctimes4%2B3%5Ctimes0%7D%7B2%2B3%7D%2C%20%5Cfrac%7B2%5Ctimes3%2B3%5Ctimes0%7D%7B2%2B3%7D%5Cright%29)
![$=\left(\frac{8+0}{5}, \frac{6+0}{5}\right)](https://tex.z-dn.net/?f=%24%3D%5Cleft%28%5Cfrac%7B8%2B0%7D%7B5%7D%2C%20%5Cfrac%7B6%2B0%7D%7B5%7D%5Cright%29)
![$=\left(\frac{8}{5}, \frac{6}{5}\right)](https://tex.z-dn.net/?f=%24%3D%5Cleft%28%5Cfrac%7B8%7D%7B5%7D%2C%20%5Cfrac%7B6%7D%7B5%7D%5Cright%29)
<em>X(x, y)</em> = (1.6, 1.2)
The coordinates of x are (1.6, 1.2).
Y = -1/2x - 1
