Answer:

Gravitational force of attraction.

Explanation:

When two bodies of masses 'm' and 'M' are separated by a distance 'r', then both the bodies experience a force of attraction towards each other. This force of attraction is called gravitational force. It is a weak force but it always act between two bodies that have mass.

The magnitude of the gravitational force is directly proportional to product of the masses and inversely proportional to the square of the distance between the masses.

This means that as the distance between the bodies is increases, the gravitational force between the bodies decreases and vice versa.

The gravitational force of attraction is given as:

F_g=\frac{GmM}{r^2}\\\\G\to \textrm{Universal Gravitational constant}

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.

Describe the main differences beA human cell has 46 chromosomes. At the end of mitosis, there are two cells, each with 46 chromo
liberstina [14]

Answer:

At the end of meiosis, there are four cells, each with 23 chromosomes, for a total of 92 chromosomes split between the four cells.

Explanation:

During meiosis, a diploid cell  (46 chromosomes) replicates its DNA (making 92 chromosomes) then undergoes two cell divisions to generate four haploid cells (23 chromosomes).

These haploid cells are the gametes which, during fertilization, fuse to become a zygote with 46 chromosomes.

How many oxygen atoms are contained in 2.74 g of Al2(SO4)3?
abruzzese [7]

Answer:

5.79 × 10^23 Oxygen atoms

Explanation:

Number of Oxygen atom in the compound = 4×3 = 12

Molar mass of Al2(SO4)3 = 342 g/mol.

No of mole = mass/molar mass = 2.74/342 = 8.01×10^-03 mole

2.74g of Al2(SO4)3 × 1 mole of Al2 (SO4)3 / 342g of Al2 (SO4)3 * 12 mole of Oxygen/ 1mole of Al(SO4)3 * 6.02×10^23 Oxygen atom/ 1 mole of Oxygen

= 5.79×10^23 Oxygen atoms
