The best answer is C."the brain interprets the size of the images"
Because, light reflects off the things in the world, then is focussed by our eye's lens. The light changes the light image we are seeing from the distal stimulus(or 3 diminutional world) to the proximal stimulus(or 2 dimensional world), but the image is not actually interpreted until it passes through the retina and optic nerve. The retina converts light into electrical impulses and the optic nerve carries those impulses to the brain. The Brain then changes the electrical impulses into a visual image.

Exactly the same way that you can photograph a mountain or a skyscraper
with the itty bitty camera in your smartphone.

Lenses are used to form a tiny image of a gigantic object.

Ask Your Teacher A basketball player shoots toward a basket 5.8 m away and 3.0 m above the floor. If the ball is released 1.7 m

const2013 [10]

Answer:

The answer to your question is vo = 5.43 m/s

Explanation:

Data

distance = d= 5.8 m

height = 3 m

height 2 = 1.7 m

angle = 60°

vo = ?

g = 9.81 m/s²

Formula

hmax = vo²sinФ/ 2g

Solve for vo²

vo² = 2ghmax / sinФ

Substitution

vo² = 2(9.81)(3 - 1.7) / 0.866

Simplification

vo² = 19.62(1.3) / 0.866

vo² = 25.51 / 0.866

vo² = 29.45

Result

vo = 5.43 m/s

In places of hot climate it is advised that the outer walls of houses be painted white. Explain.

goblinko [34]

Darker colors absorb heat, While lighter colors don't. If a house is painted black in Arizona, The black color will absorb the heat making the temperature inside the house very hot even with the AC on. If a house in Arizona is painted White, The heat will bounce off the White color, making the temperature inside the house cooler.

Hope this helps!

A ray of light traveling in water hits a glass surface. The index of refraction of the water is 1.33, and that of the glass is 1

kirza4 [7]

Answer:

$\mu=41.5\textdegree$

Explanation:

From the question we are told that:

Water index of refraction $i_w=1.33$

Glass index of refraction $i_g=1.50$

Generally the equation for Brewster's law is mathematically given by

$\theta=tan^{-1}(\frac{i_g}{i_w})$

$\theta=tan^{-1}(\frac{1.50}{1.33})$

$\theta=48.44 \textdegree$

Therefore Angle of incident to plane \mu (normal at 90 degree to the surface)

$\mu=90\textdegree-\theta$

$\mu=90\textdegree-48.44\textdegree$

$\mu=41.5\textdegree$

A tire swing hanging from a branch reaches nearly to the ground. How could you estimate the height of the branch using only a st

AlexFokin [52]

Answer:

Explanation:

With the help of expression of time period of pendulum we can calculate the height of the branch . The swinging tire can be considered equivalent to swinging bob of a pendulum . Here length of pendulum will be equal to height of branch .

Let it be h . Let the time period of swing of tire be T then from the formula of time period of pendulum

$T = 2\pi\sqrt{\frac{l}{g} }$ where l is length of pendulum .

here l = h so

$T = 2\pi\sqrt{\frac{h}{g} }$

$h = \frac{T^2g}{4\pi^2}$

If we calculate the time period of swing of tire , we can calculate the height of branch .

The time period of swing of tire can be estimated with the help of a stop watch . Time period is time that the tire will take in going from one extreme point to the other end and then coming back . We can easily estimate it with the help of stop watch .
