Explanation:
Cosmos is a system of thought.
From earth, a hydrogen source releases an emission line that has a wavelength of 410nm. observations have been made for the same line in the spectrum of light from a distant star. the star has a wavelength of 485nm (shifted toward the red end of the spectrum). provide an explanation for the differences in wavelength that were observed.
The explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the Redshift- Doppler effect.
What is the Doppler effect?The Doppler effect is the difference that occur between the frequency of a wave in relation to observer from the wave source.
The wavelength changes with change in the frequency.
How does the Doppler effect explain the redshift?As an object moves away from Earth, the waves moves to the red end of the electromagnetic spectrum and becomes elongated. This results to the increase in wavelength.
Therefore, the explanation for the differences in wavelength observed from earth and a distant star with a shift towards the red end of the spectrum is the redshift-Doppler effect.

important of science and technology in nepal(essay)
Answer:
Science and technology in Nepal, sometimes shortened to S&T in Nepal, encompass the development and challenges of scientific research and technological innovation in Nepal, and how these developments, in turn, affect Nepali society, politics, and culture. Science and technology are small but emerging fields in Nepal. The Ministry of Education, Science and Technology is the ap.ex government body tasked with the responsibility of overseeing the development of science and technology in the country.
An underdeveloped country, Nepal is plagued with problems like poverty, il.literacy, unemployment, and the like. Consequently, science and technology have invariably lagged behind in the priority list of the government. On the other hand, citing p.oor university education at home, tens of thousands Nepali students leave the country every year, with half of them never returning. These factors have been huge deterrents to the development of science and technology in Nepal.

The right-lateral transform fault occurs from the convergence of the Juan de Fuca and North American plates.
What is a transform fault?These fault occurs along which the relative motion between the two plates is parallel to the strike of the fault.
Therefore, the right-lateral transform fault occurs from the convergence of the Juan de Fuca and North American plates.

Compare and contrast The Solar Nebula Hypothesis and The Big Bang theory.
Answer:
The Nebular Hypothesis is an explanation for the formation of solar systems. The Big Bang Theory explains the origins of this universe.
Explanation:
Chalk and cheese.
COMPARISON:
1) there is no comparison as they refer to radically different things:
2) The nebular theory refers to the solar system.
The Big Bang refers to the universe as a whole.
CONTRAST:
To put the difference between the solar system and the universe in context, the solar system is measured in astronomical units (AU), the universe in billions of light years.
An AU is the distance between the sun ☀️ and earth . It takes light about 8 minutes to cover 1 AU.
A light year is the distance that light will travel in a year. So, there are about 63241 AUs in a light year.
To put that in context, Pluto (on average) is a mere 40 AUs from the sun.
The nearest star to the sun is Proxima Centauri that is 4.24 light years away. The centre of the Milky Way (our galaxy) is about 30,000 light years away. Andromeda, the nearest spiral galaxy to the Milky Way, is 2.5 MILLION light years away. The size of the observable universe is 93 BILLION light years. You get the drift.
So, the nebular theory refers to what amounts to a spec of sand on a beach when compared to what the Big Bang theory explains.

Co-linear is refers to as the two points are said to be co-linear if they line on the same line.
What do you mean by term co-planar?Co-planar is defined as a two or more points are said to be co-planar if they all lie in the same plane.
In the diagram, AB,BF,EF,AC,CE,DC are all lines while ABEF,ABCD,BDF are planes. thus, A,H,B are co-linear since they all lie on the same line. also, H and J are not co-linear.
The points A,B,E, are co-planar because they all lie in the same plane ABEF while the points A,B,D,F are not co-planar because A,B,F lie on the same plane ABEF while D lies outside the plane.
Therefore, correct option is B.

Now that the cake has been cut into 10 equal slices, how much space is covered by icing on the top of each piece of cake? the cake has a diameter of 9 inches.
The space (area) covered by icing on the top of each piece of cake is 0.636 inches squared.
What is space?Space refers to the surface or area of an object.
The space can also refer to the distance or volume covered in a measurement.
The area of space using its diameter can be computed using the following formula.
Data and Calculations:Diameter of cake = 9 inches
Radius = 4.5 inches (9 inches/2)
The radius of each of the ten slices = 0.45 inches (4.5/10)
Area = πr^2
where π = 22/7
r = radius
Area (space covered by the icing on the top of each piece of cake
= 22/7 x 0.45^2
= 22/7 x 0.2025
= 0.636 inches squared.
Thus, the space (area) covered by icing on the top of each piece of cake is 0.636 inches.
