Answer:

A) Polaris, the North star

Explanation:

Polaris, also known as the Pole star or north star, lies almost along the axis of Earth. Because of this Polaris seems to be fixed at one point in the sky while all other celestial objects change their positions in the sky due to rotation of Earth.

Since, it is fixed at one point in the sky in the North direction, explorers used to take help of Polaris to find direction in the night time. Since Polaris is not the brightest star in the night sky (it is 48th brightest star) our ancestors took help of constellations to find it. One of the method was to use Big Dipper of "Ursa Major" constellation. The pointer stars (Merak and Dubhe) of big dipper point towards the Polaris. One can easily spot it in the sky as well.

Why can work be thought of as the transfer of energy? Please help it's physics
deff fn [24]
That is because work requires energy. According to the law of conservation of energy, it cannot be created or destroyed. When doing work, energy change forms and gets transferred to the object until it is released.
for example, when you lift up an object and place it on a higher elevation, you transferred energy to it and gave it potential energy. The potential energy is transformed into kinetic energy when the object falls down, and if it hits a surface, the energy will scatter, vibrating the areas around it and producing sound.
Also, work= force X distance. The energy does not go away, but rather get changed into some other form of energy

You get a new pair of sunglasses as a birthday gift from a friend. When wrapping the present, your friend has removed the price
Gwar [14]

Answer:

Explanation:By using the sunglasses while looking at If your sunglasses are polarized, instead of only seeing the surface of a lake or river, you will suddenly be able to see through the glare and into the water below.

Another one is by comparing two sunglasses, hold your glasses and another one simultaneously and look through both pairs at the same time. Then, rotate one pair of sunglasses about 60 degrees. If both pairs of glasses are polarized, the overlapping area will darken as they filter out excess light. If your pair isn't polarized, however, you won't notice any difference.

Also it can be determined by simple computer test If you rotate your glasses sideways while looking at a computer monitor through polarized glasses, portions of your screen will become blank or go dark. The same also applicable to LCD display screens such as the ones on a gas pump.
