How does the gravity of moon compare with the earth

  • Answers:
  • We know that gravity is a force that attracts all physical objects towards each other "Weight" is a measure of that gravitational pull. the greater the mass of an object, the stronger the force of gravity. The Moon's mass is about 1.2% of the Earth's mass (1/80th), so the Moon's gravity is much less than the Earth's gravity: 83.3% (or 5/6) less to be exact. Other related facts: the Moon is 1/4 the size of the Earth by diameter, and 1/50 the size by volume.

     The primary difference between the gravities of the Earth and the Moon is that the moon’s gravity is weaker due to the moon being smaller in size, whereas, the earth is bigger in size, and has more massive objects that exert more gravity Each and every person is falling towards the Earth at an accelerating rate of 9.8 meters/second². Gravity basically comes from mass. The amount of gravity reduces gradually with the reduction in distance. As a result, the force of gravity that one feels on the surface of Earth, is much different from what one would experience at the distance of the Moon, or at a distance further from it. The force of gravity of Earth also changes depending on where a person is standing on it. The primary reason of this is because the Earth is rotating. The gravity of Earth at the equator is 9.789 m/s2, while the force of gravity at the poles is 9.832 m/s2.

    Gravity on the Moon is much less. The moon is smaller and has much less mass, it pulls with less gravity. Actually, if one could stand on the plane of the Moon, he would experience only 17% force of gravity that one would experience on Earth. With gravity on the moon so low, a person can even jump higher than he/she can on Earth. The acceleration due to gravity on the surface of the Moon is 1.62 m/s2, about 16.6% of that on the Earth's surface.

  • Answers:
  • A rectifier is an electrical device that converts alternating current (AC), which periodically reverses direction, to direct current (DC), which flows in only one direction. The process is known as rectification, since it "straightens" the direction of current.

    Half-wave rectification : In half-wave rectification of a single-phase supply, also called uncontrolled one-pulse midpoint circuit, either the positive or negative half of the AC wave is passed, while the other half is blocked. Mathematically, it is a ramp function (for positive pass, negative block): passing positive corresponds to the ramp function being the identity on positive inputs, blocking negative corresponds to being zero on negative inputs. Because only one half of the input waveform reaches the output, mean voltage is lower. Half-wave rectification requires a single diode in a single-phase supply, or three in a three-phase supply. Rectifiers yield a unidirectional but pulsating direct current; half-wave rectifiers produce far more ripple than full-wave rectifiers, and much more filtering is needed to eliminate harmonics of the AC frequency from the output.

  • Photosynthesis is a process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose, photosynthesis provides the basic energy source for virtually all organisms. An extremely important byproduct of photosynthesis is oxygen, on which most organisms depend.

    Photosynthesis occurs in green plants, seaweeds, algae, and certain bacteria. Photosynthesis is a source of food, energy, and oxygen, making it one of the most important biochemical processes known.

    Photosynthesis is a very complex process,the light-dependent reaction, the chloroplast traps light energy and converts it into chemical energy contained in nicotinamide adenine dinucleotide phosphate (NADPH) and adenosine triphosphate (ATP), two molecules used in the second stage of photosynthesis. then light-independent reaction (formerly called the dark reaction), NADPH provides the hydrogen atoms that help form glucose, and ATP provides the energy for this and other reactions used to synthesize glucose.

  • Council of Ministers are the ministers appointed by the President of India on advice of the Prime Minister. Council of Ministers are categorized into three categories.

    1 Cabinet Ministers- They act as head of important ministries of the central government. For e.g- Defense Ministry, Home Ministry, Finance Ministry etc. They are the integral part of Cabinet, as a result of which, they play a very important role in framing policies.

    2 Ministers of state- They can be given Independent charge of ministries or can be attached to the cabinet ministers. When attached to the cabinet ministers, they work under the guidance of cabinet ministers. The difference from the cabinet ministers lie in the fact that, they do not attend the cabinet meetings as they are not the part of cabinet (unless specially invited when something related to their ministry is being considered by the cabinet)

    3 Deputy Ministers- They are never given independent charge of ministry( unlike ministers of state), and always remain attached to the cabinet ministers or ministers of state. They assist to discharge the political, administrative and parliamentary duties effectively. They are neither part of cabinet nor attend the cabinet meetings.

  • The powers and functions of prime minister can be studied under the following heads:

    In Relation to Council of Ministers: Since the prime minister stands at the head of the council of ministers, the other ministers cannot function when the prime minister re-signs or dies. In other words, the resignation or death of an incumbent prime minister automatically dissolves the council of ministers and thereby generates a vacuum. The resignation or death of any other minister, on the other hand, merely creates a vacancy.

    The prime minister enjoys the following powers as head of the Union council of ministers:
    1. He recommends persons who can be appointed as ministers by the president. The president can appoint only those persons as ministers who are recommended by the prime minister.
    2. He presides over the meeting of council of ministers and influences its decisions.
    3. He can ask a minister to resign or advise the president to dismiss him in case of difference of opinion.
    4. He allocates and reshuffles various portfolios among the ministers.
    5. He guides, directs, controls, and coordinates the activities of all the ministers.
    6. He can bring about the collapse of the council of ministers by resigning from office.

    In Relation to the President: The prime minister enjoys the following powers in relation to the president:
    1. He is the principal channel of communication between the president and the council of ministers.
    2. He advises the president with regard to the appointment of important officials like attorney general of India, comptroller and auditor general of India, chairman and members of the UPSC, election commissioners, chairman and members of the finance commission and so on.

    In Relation to Parliament :The prime minister is the leader of the Lower House. In this capacity, he enjoys the following powers:
    1. He advises the president with regard to summoning and proroguing of the sessions of the Parliament.
    2. He can recommend dissolution of the Lok Sabha to president at any time.
    3. He announces government policies on floor of the House.

    Other Powers & Functions:
    1. He is the chairman of the Planning Com-mission, National Development Council, National Integration Council and Inter-State Council.
    2. He plays a significant role in shaping the foreign policy of the country.
    3. He is the chief spokesman of the Union government.
    4. As a leader of the nation, he meets various sections of people in different states and receives memoranda from them regarding their problems, and so on.
    5. He is the crisis manager-in-chief at the political level during emergencies. He is leader of the party in power and the political head of the services.

  • The earth surface attracts the moon with the same force with which the moon attracts the earth. According to Newton’s 3rd law, these two forces are equal and opposite. Also by the universal law of gravitation.

    According to the Newton’s 3rd law of motion, the moon also attracts the earth with a force equal to that with which the earth attracts the moon. Since the earth is much larger than the moon so, the acceleration produced on the earth surface (acceleration α 1/m) can not be noticed.

  • Forces of speed and gravity keep the Moon in a constant orbit around Earth. The Moon, Earth's natural satellite, seems to hover in the sky, unaffected by gravity. However, the reason the Moon stays in orbit is precisely because of gravity , a universal force that attracts objects. With the right combination of speed and gravity, satellites can fall around, instead of into, the body that they orbit.

  • Vladimir Lenin led the Russian Bolsheviks in a successful takeover of the provisional government that had been created when Nicholas II abdicated the throne a few months earlier in the face of mass protests and riots against his rule. Known as the "October Revolution," the 1917 change of government that occurred when Lenin and the Bolsheviks stormed the Winter Palace on the night of October 26 led to the creation of the first socialist state with Lenin as its head. Lenin went on to survive two assassination attempts, and he remained the leader of the Communist Party and Premier of the Soviet Union until his death from a stroke in 1924.

    The October Revolution was not the first Bolshevik attempt to gain control of the Russian government. Lenin and his supporters attempted to take power earlier that same year in July, but the attempt failed. Lenin was forced to flee to Finland as a result of the failed takeover, but continued to direct and encourage the Bolshevik uprising while remaining in hiding across the Finnish border.

    Lenin returned to Russia in October and directed the successful Bolshevik takeover of the government from a hidden base of operations within the Smolny Institute in St. Petersburg. Under Lenin's administration, the former Russian Empire was transformed into the Russian Soviet Federative Socialist Republic in 1917 and became the Soviet Union in 1922. In addition to his role as a political leader, Lenin was also known as a political theorist. Although based on Marxism, Lenin's political theories are commonly referred to as "Leninism."
