Light waves are transmitted across the cornea and enter the eyes through the pupil.
<h3>
FURTHER EXPLANATION</h3>
The eyes and the brain are important in helping people see. Light passes through the eyes and this light gets transformed into electrical signals which are sent to the brain that helps make sense of the object that is seen.
<h3 /><h3>How People See</h3>
- Light is incident on an object (or strikes an object). Some of it get absorbed, some are reflected into a human's eye.
- Light that bounces off the object is transmitted across the cornea, the transparent outer layer of the eye. It refracts the light and makes things look sharp and clear.
- Then the light enters the pupil which is the opening in the eye controlled by the iris or the colored part of the eye. The iris changes the size of the pupil and controls the amount of light that enters the eye. When there is bright light, the pupil becomes smaller. In dim light, the opposite happens and the pupil becomes bigger.
- At the back of the pupil is the lens which again helps focus the light. Its shape changes depending on the distances of the objects that is being looked at.
- The light rays are focused by the lens so that they all converge in the retina which is at the back of the eye. The retina has many specialized cells which are sensitive to light. These cells transform light energy into electrical signals or nerve impulses which form a rough inverted image of the object the person is looking at.
- The electrical signals travel to the brain through the optic nerve. The brain turns the image upright and adds more detail to the vision.

The most likely toxic chemicals that is found in baby bottles is called BPA. If high doses of this chemical is consumed, it might shut down the response system of estrogen in the babies. It could also possibly change the babies ability of producing ordinary thyroid hormones.
Law makers can address this possibility by making a law that bans the creation of a baby bottles plastic that contains these toxic chemicals. This provides with a strict interpretation of the precautionary principle because it is ‘banning’ all the bottles plastic that contains toxic chemicals. Banning is a strict interpretation.
Law makers can also make a law that limits the doses of this toxic chemical that can be found in the bottles plastic. This is a strict interpretation because there is a limit, and if the producers go above the limit, there is consequences to face.
Answer:
Explanation:
The speed of the ball in meters per second is
Where t denotes the number of seconds since the ball has been thrown and 
is the initial speed of the ball. Then:
If the ball travels 25 meters during the first 2 seconds after it is thrown, what was the initial speed of the ball
Also, for constant acceleration motion, the average velocity is equal to the sum of final and initial velocities divided by 2 and to the distance divided by the time:
Where you know:
Substituting (the units are ommited in the equationn, but added at end of the answer):
Thus, you have a system of equations:
Substituting the second into the first:
