Primary Component of a Nebula: Hydrogen
A nebula is a vast cloud of gas and dust in space, often considered as the birthplace of stars. It is composed of various elements, but the primary component of a nebula is hydrogen (H).
Explanation:
1. Composition of a Nebula:
A nebula is predominantly made up of hydrogen gas, which accounts for about 90% of its composition. Hydrogen atoms are the most abundant in the universe and serve as the building blocks for stars and galaxies. Other elements, such as helium, carbon, oxygen, nitrogen, and trace amounts of heavier elements, are also present in nebulae.
2. Formation of a Nebula:
Nebulae are formed through various processes, including the gravitational collapse of interstellar clouds, supernova explosions, and the remnants of dying stars. These events result in the dispersal of gas and dust into space, creating vast clouds known as nebulae.
3. Ionization and Excitation:
Nebulae can be classified into different types based on their appearance and the processes occurring within them. One common type is an emission nebula, also known as a HII region. These nebulae are primarily composed of ionized hydrogen gas (H+). Massive stars emit intense ultraviolet radiation, which ionizes the surrounding hydrogen atoms, causing them to lose an electron and become positively charged. This ionized hydrogen emits visible light, giving emission nebulae their characteristic red glow.
4. Role of Hydrogen in Star Formation:
Hydrogen plays a crucial role in the formation of stars. Within a nebula, regions of higher density and gravity can cause the gas and dust to collapse inward. As the hydrogen gas contracts, it heats up, eventually reaching a temperature and density where nuclear fusion can occur. This fusion process converts hydrogen into helium, releasing enormous amounts of energy. The outward pressure generated from the fusion reactions counteracts the gravitational collapse, resulting in a stable star.
Conclusion:
In summary, the primary component of a nebula is hydrogen. It constitutes the majority of a nebula's composition and is crucial for the formation of stars. Nebulae provide the necessary raw materials, including hydrogen gas, for the birth of new stars and the continuation of stellar evolution.

Meghana Nambiar answered |
The Big Bang Theory is a widely accepted scientific explanation for the origin and evolution of the universe. It proposes that the universe began as a single point of high-density and high-temperature and has been expanding ever since. This theory is supported by various lines of evidence, including the observed expansion of galaxies, the abundance of light elements in the universe, and the cosmic microwave background radiation.
The Big Bang Theory can be explained in detail as follows:
1. Initial Singularity:
According to the Big Bang Theory, the universe originated from an extremely hot and dense state known as the initial singularity. At this point, all matter, energy, space, and time were concentrated in a single infinitesimal point.
2. Expansion and Cooling:
Shortly after the initial singularity, the universe began to rapidly expand and cool down. This expansion is often referred to as the "Big Bang." As the universe expanded, the temperature and density decreased, allowing the formation of subatomic particles like protons, neutrons, and electrons.
3. Formation of Matter:
As the universe continued to expand and cool, the subatomic particles started to combine and form atoms, primarily hydrogen and helium. This process is known as nucleosynthesis. These atoms then clumped together under the influence of gravity, eventually forming stars, galaxies, and other celestial structures.
4. Cosmic Microwave Background Radiation:
Around 380,000 years after the Big Bang, the universe had cooled down enough for atoms to capture electrons and become neutral. This event, known as recombination, allowed photons to travel freely through space, resulting in the release of the cosmic microwave background radiation (CMB). The CMB is a faint radiation that permeates the entire universe and is considered as one of the strongest pieces of evidence supporting the Big Bang Theory.
5. Expansion of the Universe:
Observations of galaxies and their redshifts have provided strong evidence for the ongoing expansion of the universe. The farther away a galaxy is, the faster it appears to be moving away from us. This observation supports the idea that the universe is expanding from a single point, as predicted by the Big Bang Theory.
In conclusion, the Big Bang Theory states that the universe began as a single point of high-density and high-temperature and has been expanding ever since. The theory is supported by various scientific observations and provides a comprehensive explanation for the origin and evolution of the universe.

Ananya Ahuja answered |
The primary driving force behind the expansion of the universe is Dark Energy.
Explanation:
1. Introduction:
The expansion of the universe refers to the phenomenon where the distance between galaxies and other cosmic structures is constantly increasing over time. This observation was first made by Edwin Hubble in the 1920s and has since been confirmed by various astronomical observations.
2. Dark Energy:
Dark Energy is a hypothetical form of energy that is believed to permeate all of space and is responsible for the accelerated expansion of the universe. It is called "dark" because it does not interact with light or other electromagnetic radiation, making it difficult to detect directly.
3. Discovery of Dark Energy:
The existence of Dark Energy was first proposed in the late 1990s when astronomers observed that distant supernovae were fainter than expected, indicating that the expansion of the universe is accelerating. This discovery was awarded the Nobel Prize in Physics in 2011.
4. Role of Dark Energy:
Dark Energy acts as a repulsive force that counteracts the gravitational attraction between galaxies and other cosmic structures. While gravity tends to pull objects together, Dark Energy pushes them apart, causing the expansion of the universe to accelerate over time.
5. Understanding Dark Energy:
Despite its importance, Dark Energy remains poorly understood. It is often associated with the cosmological constant, a term introduced by Albert Einstein in his general theory of relativity. The cosmological constant represents a constant energy density in space, which can drive the accelerated expansion.
6. Proportion of Dark Energy:
Dark Energy is believed to account for about 68% of the total energy content of the universe, with Dark Matter accounting for about 27% and ordinary matter making up the remaining 5%. This means that Dark Energy is the dominant factor influencing the expansion of the universe.
7. Future of the Universe:
The presence of Dark Energy and its acceleration of the universe's expansion have significant implications for the future of the cosmos. It is believed that as the universe continues to expand, galaxies will become more and more separated, eventually leading to a "Big Freeze" scenario where the universe becomes cold and dark.
Conclusion:
In conclusion, Dark Energy is the primary driving force behind the expansion of the universe. Its repulsive nature counteracts gravitational attraction and causes the acceleration observed in the expansion. While Dark Energy remains a mysterious phenomenon, further research and observations are ongoing to better understand its nature and implications for the future of the universe.

Keerthana Sen answered |
Electron is the elementary particle that has an antiparticle with the same mass but opposite electrical charge. An antiparticle is a particle that has the same mass as its corresponding particle but carries the opposite charge.
Below is a detailed explanation for each option:
a) Proton: The proton is a positively charged elementary particle found in the nucleus of an atom. Its antiparticle is called the antiproton, which has the same mass as a proton but carries a negative charge. Therefore, the antiparticle of a proton does not have the same electrical charge as the proton.
b) Neutron: The neutron is a neutral elementary particle found in the nucleus of an atom. Since it has no electrical charge, its antiparticle would also have no charge. Therefore, the antiparticle of a neutron does not have the same electrical charge as the neutron.
c) Electron: The electron is a negatively charged elementary particle found orbiting the nucleus of an atom. Its antiparticle is called the positron, which has the same mass as an electron but carries a positive charge. The positron is the antiparticle of the electron and has the same mass but opposite electrical charge. Therefore, the correct answer is option 'C'.
d) Neutrino: The neutrino is a neutral elementary particle with very little mass. It is not electrically charged, so it does not have an electrical charge to be opposite to. Therefore, the antiparticle of a neutrino does not have the same electrical charge as the neutrino.
In summary, the electron is the elementary particle that has an antiparticle with the same mass but opposite electrical charge. The antiparticle of an electron is called a positron, which has the same mass as an electron but carries a positive charge.

Frequency Band Characteristics:
- Different frequency bands have different characteristics in terms of signal propagation, interference, and antenna size requirements.
- The L-band frequency range falls between 1 to 2 GHz, which is in the microwave region of the electromagnetic spectrum.
- Microwave frequencies are commonly used for satellite communication due to their ability to penetrate the Earth's atmosphere and experience less interference from weather conditions.
Advantages of L-band for GPS:
1. Signal Penetration: L-band signals have a good ability to penetrate through various obstacles such as buildings and tree canopies. This makes them suitable for providing accurate positioning information even in urban areas or dense forests.
2. Interference: L-band signals experience less interference from atmospheric conditions, such as rain or fog, compared to higher frequency bands. This ensures reliable signal reception and reduces the chances of signal degradation.
3. Antenna Size: The wavelength of L-band signals is relatively large compared to higher frequency bands. This allows for the design of smaller and more compact GPS antennas, making them easier to integrate into handheld devices or vehicles.
4. Availability of Frequencies: The L-band frequency range is allocated specifically for satellite navigation and positioning systems like GPS. This ensures that the frequencies are reserved and not heavily congested with other communication systems.
5. Global Coverage: The GPS system is designed to provide global coverage, and L-band signals are capable of traveling long distances without significant degradation. This allows GPS receivers to obtain accurate positioning information anywhere on Earth.
In conclusion, the L-band frequency band is used by GPS carriers due to its advantages in signal penetration, interference resistance, compact antenna design, availability of frequencies, and global coverage capabilities.
