How does the distance from a flashlight to a screen affect the size of the illuminated area?​

Biology

Mumz [18]3 years ago

Answer:

The bigger the distance between the lit torch and the screen, the bigger the illumination area.

Explanation:

Part of the reason is that with increasing distance the light, beam interacts with air molecules that disperse it. The more the air molecules (and note that these air molecules have kinetic energy) it interacts with, the higher the dispersion. It is also important to note that light waves have duality. They also behave like a wave. As a wave disperses from a single point (the torch), it propagates outwards in all direction. The area covered, therefore, increases with distance. Its intensity will also decrease with distance.

Please help me I don’t understand it.

Answer:

1) bay - 0%

  cream - 0%

  buckskin - 100%

2) cream - 25%

    bay - 25%

   buckskin - 50%

3) co-dominance

Explanation:

Ok so a run down on Punnett Squares,  all you have to do is put the parent's genes on the top and right hand side and combine those two genes in the middle as I did in the picture.  Now, co-dominance, this basically means that there is no dominant allele.  For example, imagine a white flower (W) and a red flower (R).  If these two plants were to breed, you would get a pink flower (WR).  This means the red allele and the white allele are both co-dominant.  It is basically a combination of both genes that result in a mixed phenotype of the two genes, aka red and white makes pink.  This is also how you get an AB blood type.

I hope this helps!

Nikolay [14]
A nuclear power plant will use nuclear energy to power the town. While nuclear energy is perhaps one of the most effective ways to provide power, a nuclear accident is very dangerous, and could destroy an environment and its organisms. There was a nuclear accident in Chernobyl, Ukraine, in the 1900s. people had to evacuate because of it.
