Answer:

  • <u><em>Tau Ceti, 11.9 light years from the Sun</em></u>

Explanation:

The table is:

<em>Star                           Light Years from the Sun</em>

<em>Chara                        27.3 light years</em>

<em>Tau Ceti                    11.9 light years</em>

<em>Zeta Leporis            70.2 light years</em>

<em>Epsilon Reticuli        59.5 light years</em>

<em>Light years</em> is a unit of distance. It is the distance that the light travels in one year.

Since the speed of light is a constant, c ≈ 300,000,000 m/s, one light year is equal to the product of c by the number of seconds in a year (about 31,540,000‬ seconds).

Thus, the smaller the number of light years a star is from the Sun the closer the distance between the star and the Sun.

Rank the distances in increasing order:

  •  11.9 light years < 27.3 light years < 59.5 light years < 70.2 light years

Then, Tau Ceti, with 11.9 light years is the closest to the Sun.

What are the characteristics of the two systems of government in this region? Explain in detail.
Anna11 [10]

Answer:

space agency of the Republic of India, headquartered in Bengaluru. It operates under Department of Space (DoS) which is directly overseen by the prime minister of India while chairman of ISRO acts as executive of DoS as well. ISRO is the primary agency in India to perform tasks related to space based applications, space exploration and development of related technologies.[6] It is one of six government space agencies in the world which possess full launch capabilities, deploy cryogenic engines, launch extraterrestrial missions and operate large fleets of artificial satellites.[7][b]

The Indian National Committee for Space Research (INCOSPAR) was established by Jawaharlal Nehru[8] under the Department of Atomic Energy (DAE) in 1962, with the urging of scientist Vikram Sarabhai recognising the need in space research. INCOSPAR grew and became ISRO in 1969,[9] also under the DAE.[10][11] In 1972, the Government of India had set up a Space Commission and the Department of Space (DOS),[12] bringing ISRO under the DOS. The establishment of ISRO thus institutionalised space research activities in India.[13] It is managed by the DOS, which reports to the Prime Minister of India.[14]

ISRO built India's first satellite, Aryabhata, which was launched by the Soviet Union on 19 April 1975.[15] It was named after the mathematician Aryabhata. In 1980, Rohini became the first satellite to be placed in orbit by an Indian-made launch vehicle, SLV-3. ISRO subsequently developed two other rockets: the Polar Satellite Launch Vehicle (PSLV) for launching satellites into polar orbits and the Geosynchronous Satellite Launch Vehicle (GSLV) for placing satellites into geostationary orbits. These rockets have launched numerous communications satellites and Earth observation satellites. Satellite navigation systems like GAGAN and IRNSS have been deployed. In January 2014, ISRO used an indigenous cryogenic engine CE-7.5 in a GSLV-D5 launch of the GSAT-14.[16][17]

ISRO sent a lunar orbiter, Chandrayaan-1, on 22 October 2008, which discovered lunar water in the form of ice,[18] and the Mars Orbiter Mission, on 5 November 2013, which entered Mars orbit on 24 September 2014, making India the first nation to succeed on its maiden attempt to Mars, as well as the first space agency in Asia to reach Mars orbit.[19] On 18 June 2016, ISRO launched twenty satellites in a single vehicle,[20] and on 15 February 2017, ISRO launched one hundred and four satellites in a single rocket (PSLV-C37), a world record.[21][22] ISRO launched its heaviest rocket, Geosynchronous Satellite Launch Vehicle-Mark III (GSLV-Mk III), on 5 June 2017 and placed a communications satellite GSAT-19 in orbit. With this launch, ISRO became capable of launching 4-tonne heavy satellites into GTO. On 22 July 2019, ISRO launched its second lunar mission Chandrayaan-2 to study the lunar geology and the distribution of lunar water.

Future plans include development of the Unified Launch Vehicle, Small Satellite Launch Vehicle, development of a reusable launch vehicle, human spaceflight, a space station, interplanetary probes, and a solar spacecraft mission.

For the reaction: 3 H2(g) + N2(g) &lt;--&gt; 2 NH3(g), the concentrations at equilbrium were [H2] = 0.10 M, [N2] = 0.10 M, and [
masya89 [10]

The equilibrium constant, k of the reaction in which case, the concentrations of the given reactants and products are as indicated is; Choice A; K = 3.1 x 10⁵

<h3>What is the equilibrium constant , k of the reaction as described in the task content?</h3>

It follows from above that the concentrations of the reactants and products are as follows; [H2] = 0.10 M, [N2] = 0.10 M, and [NH3] = 5.6 M at equilibrium.

Hence, the equilibrium constant of the reaction in discuss is;

K = [5.6]²/[0.10]³[0.10]

k = 5.6² × 10⁴

k = 3.136 × 10⁵

K = 3.1 × 10⁵.
