Answer:
The angle of refraction of sheet 3 when sheet 1 is on top of it is
Explanation:
From the question we are told that
The angle of incidence is
The angle of refraction angle for sheet 1 is
The angle of refraction for sheet 3 is
According to Snell's law
Where are refractive index of sheet 1 and sheet 2
=>
Also when sheet 3 in on top of sheet 2
substituting for
=>
when sheet 1 in on top of sheet 3
where is the angle of refraction when sheet 1 is on top of sheet 3
substituting for
=>
substituting values
=>
=>
We learned that We are in the disk of the Galaxy, about 5/8 of the way from the center.

</h3><h3>What is the work of Harlow Shapley?</h3>
Shapley, who was based in Boulder, Colorado, utilised Cepheid variable stars to determine the Milky Way Galaxy's size and the Sun's location within it through the use of parallax. He put out his "liquid water belt" theory, now referred to as the idea of a livable zone, in 1953.
Milky way Galaxy-
There are many stars, grains of dust, and gas in the Milky Way. It is known as a spiral galaxy because, from the top or bottom, it would appear to be whirling like a pinwheel. About 25,000 light-years from the galaxy's nucleus, the Sun is situated on one of the spiral arms.
Approximately 5/8 of the way from the galaxy's nucleus, we are in the disc. William Herschel believed that the Sun and Earth were about in the middle of the vast cluster of stars known as the Milky Way.

Answer:
Law of conservation of mass
Explanation:
Answer:
0.02325 m^3
Explanation:
P1 = 100000Pa , v1 = 0.0279m^3
P2= 120000Pa . V2 = ?
as mass and temperature are constant using ratio method for Boyle'slaw
P2V2= P1V1
or V2= P1V1/P2
V2 = 100000×0.0279/120000
V2= 0.02325 m^3
Answer:
the first one by using second person point of view
