When it is directed at a mirror it is reflected
When it is directed at a glass block it refracts
When it is directed through a prism the light splits to form a spectrum ( red orange yellow green blue indigo and violet )
Hope this is ok
Answer:
Explanation:
We know that,
Distance(S)= 100 m
Initial velocity (u)= 15 m/s
Final velocity (v) = 0m/s [As the car stops at last]
We know that,
![2aS=v^2-u^2](https://tex.z-dn.net/?f=2aS%3Dv%5E2-u%5E2)
![a= \frac{v^2-u^2}{2S} \\](https://tex.z-dn.net/?f=a%3D%20%5Cfrac%7Bv%5E2-u%5E2%7D%7B2S%7D%20%5C%5C)
Substitututing values for v,u,S we get,
![a=\frac{0^2-15^2}{2*100} \\a=\frac{-225}{200} \\a=-1.125\\Approxiametly, -1 (to the nearest whole number)](https://tex.z-dn.net/?f=a%3D%5Cfrac%7B0%5E2-15%5E2%7D%7B2%2A100%7D%20%5C%5Ca%3D%5Cfrac%7B-225%7D%7B200%7D%20%5C%5Ca%3D-1.125%5C%5CApproxiametly%2C%20-1%20%28to%20the%20nearest%20whole%20number%29)

Answer:
gravity
Explanation:
Though gravity holds planets, stars, solar systems and even galaxies together, it turns out to be the weakest of the fundamental forces, especially at the molecular and atomic scales.
