Answer: 340m
Explanation:
Given that:
Streets are constructed from 10 m pieces;
A lamppost is placed at both ends and at every 10 m along its length ;
A lamppost is also placed at every notice board along its length :
Given that:
Einstein Street has 42 lamppost and 7 notice boards :
So,
7 lamppost for 7 notice boards :
Lamppost left = 42 - 7 = 35 lamppost
2 lamppost placed at both ends :
Lamppost left = 35 - 2 = 33 lamppost
Hence, the remaining is placed at 10 m along its length:
Hence, length of Einstein street :
33 lamppost each placed 10m from the starting lamppost = (33 * 10) = 330m
Distance between 33rd lamppost and the ending lamppost = 10m
Hence, total length = (330 + 10) = 340 m
Light waves are transmitted across the cornea and enter the eyes through the pupil.

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.

A free-trade zone is by definition “a place where trade is left to happen without tariffs(tax on imports/exports), quotas, or other restrictions”. An example of a free-trade zone is the European Union. There are no tariffs, quotas, or other restrictions placed on trading within the EU countries (they even share a currency). This allows for them to place products at a cheaper price for good quality and still get enough money to grow wealth within the different countries.
