Chromatic aberration comes from the fact that different wavelengths of light travel at different speeds through the material of
gtnhenbr [62]

Answer:

 y_red / y_blue = 1.11

Explanation:

Let's use the constructor equation to find the image for each wavelength

         1 /f = 1 /o + 1 /i

Where f is the focal length, or the distance to the object and i the distance to the image

Red light

           1 / i = 1 / f - 1 / o

           1 / i_red = 1 / f_red - 1 / o

           1 / i_red = 1 / 19.57 - 1/30

           1 / i_red = 1,776 10-2

           i_red = 56.29 cm

Blue light

            1 / i_blue = 1 / f_blue - 1 / o

            1 / i_blue = 1 / 18.87 - 1/30

            1 / i_blue = 1,966 10-2

            i_blue = 50.863 cm

Now let's use the magnification ratio

             m = y ’/ h = - i / o

             y ’= - h i / o

Red Light

            y_red ’= - 5 56.29 / 30

            y_red ’= - 9.3816 cm

Light blue

            y_blue ’= 5 50,863 / 30

            y_blue ’= - 8.47716 cm

The ratio of the height of the two images is

            y_red ’/ y_blue’ = 9.3816 / 8.47716

            y_red / y_blue = 1,107

            y_red / y_blue = 1.11

A spring with a spring constant of 45 N/m is pulled 1.4 m away from its equilibrium position. How much potential energy is store
Luda [366]

Elastic potential energy is given by:

E =\dfrac{1}{2}kx^2

Where k is the spring constant in N/m and x is displacement from equilibrium position in m. Evaluating:

E =\dfrac{1}{2}kx^2 = \dfrac{1}{2}(45\;N/m)(1.4\;m)^2 = 44.1\;J

A/ The potential energy is stored in the spring is 44.1 J.

What happens if actions taken during the fragmentation stage are only partially successful?
gogolik [260]

Answer:

The community may regress to the denial stage or stagnate in the fragmentation stage.

Explanation:

An habitat is a place where organisms live. It provides the basic essentials of living for the organisms. Examples are; terrestrial, aquatic etc. Fragmentation of an habitat can occur due to some natural or artificial processes.

Habitat fragmentation is the process in which a large area of habitat is transformed into a number of smaller areas. These smaller patches are segregated from each other.

This may cause the extinction of some species due to edge effect.

If actions taken during the fragmentation stage are partially successful, the community in the habitat may regress to the denial stage or stagnate in the fragmentation stage.
