In reality we don't see the galaxy we see it's reflection .. the light hits or got emitted by the star travel all the way long to hit our eyes .. we see their reflection . everything around you that you see is it's reflection

Answer:
In wind turbines, the blades rotate due to the wind.
Explanation:
In wind turbines, the blades rotate due to the wind.<u> While the blade rotates the generator connected to it also rotates.</u> Thus the <u>kinetic energy from the wind initiates the electric generator which in turn produces the electricity.</u>
Thus the<u> kinetic energy of the wind is converted to electricity.</u>
<u></u>
Hope this helps!
Have a Wonderful Friday!
-Good Luck on your Homework- :)
Answer:
Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know that thermal motion of the atoms and molecules occurs at any temperature above absolute zero.) Heat transferred from the burner of a stove through the bottom of a pan to food in the pan is transferred by conduction.
Convection is the heat transfer by the macroscopic movement of a fluid. This type of transfer takes place in a forced-air furnace and in weather systems, for example.
Heat transfer by radiation occurs when microwaves, infrared radiation, visible light, or another form of electromagnetic radiation is emitted or absorbed. An obvious example is the warming of Earth by the Sun. A less obvious example is thermal radiation from the human body. I hope this helps you

Answer:
Explanation:
The formula for the single-slit diffraction is
where
y is the distance of the n-minimum from the centre of the diffraction pattern
D is the distance of the screen from the slit
d is the width of the slit
is the wavelength of the light
In this problem,
, with n=2 (this is the distance of the 2nd-order minimum from the central maximum)
Solving the formula for d, we find:
The vertical displacement of the wave is measured from
the equilibrium to the crest and is called the amplitude.
