  • Answers:
  •  

    Plagiarism allegations can cause a student to be suspended or expelled. Their academic record can reflect the ethics offense, possibly causing the student to be barred from entering college from high school or another college. Schools, colleges, and universities take plagiarism very seriously. Most educational institutions have academic integrity committees who police students. Many schools suspend students for their first violation. Students are usually expelled for further offences.

What is globalisation? 

Posted by Anirudh S Kumar (Jan 18, 2017) (Question ID: 1458)

  • Answers:
  • Globalization is the free movement of goods, services and people across the world in a seamless and integrated manner.

    Globalization can be thought of to be the result of the opening up of the global economy and the concomitant increase in trade between nations

    . In other words, when countries that were hitherto closed to trade and foreign investment open up their economies and go global, the result is an increasing interconnectedness and integration of the economies of the world.

 the sum of intiger and their reciprocal is 145/12. Find the intiger ?

Posted by Pankaj Asery (Jan 18, 2017) (Question ID: 1452)

  • Answers:
  • Solution:

    Let the integer = x

    Then reciprocal = 1/x

    According to Question

    x + 1/x = 145/12

    => (x2+1)/x = 145/12

    => 12x2 + 12 = 145x

    => 12x- 145x + 12 = 0

    => 12x2- 144x - x + 12 = 0

    => 12x(x - 12) - 1(x - 12) = 0

    => (x - 12)(12x - 1) = 0

    => x = 12 and x = 1/12

    as X is integer x can't be 1/12

    Therefore the required integer is 12

  • Let the integer be x.

    x + 1/x = 145/12

    12x2 - 145x + 12 = 0

    12x2 - 144x - x + 12 = 0

    12x(x - 12) - 1(x - 12) = 0

    (x - 12)(12x - 1) = 0

    x = 12 and x = 1/12

    Therefore the required integer is 12.

Why the jute industries are located near hugli river basin

Posted by Shagun Vishwakarma (Jan 18, 2017) (Question ID: 1450)

  • Answers:
  • The reasons for this concentration of jute mills in Hugli River basin are as under:

    1. West Bengal is the store house of jute. It produces the highest number of bales of jute fibre.

    2. This industry requires a lot of water which is easily available from the Hugli River.

    3. Iron and coal which are required for the installation and running of jute factories are also available from the nearby mines of Raniganj.

    4. Cheap Labour is easily available because of incoming labour from the adjoining provinces of Bihar and Orissa.

    5. If some more raw material of jute is required it can easily be imported from Bangladesh.

    6. Last but not the least, Calcutta is a good harbour which can easily export the jute manufactures to other countries of the world through its great network of ships.

A divergent lens has a focal length of 20cm.at what distance should an object of height 4cm from the optical centre of the lens be placed so that its image is formed 10cm away from the lens.find the size of the image also

Posted by BAIJU JOSEPH (Jan 18, 2017) (Question ID: 1449)

  • Answers:
  • Ans. Distance between the object and the lens (u )= -10cm
    Focal length (f) = 20 cm
    Distance between the image and the lens v = ?

    Using Lens Formula 

    1f = 1v-1u

    => 120 = 1v - 1-10

    => 1v = 120 - 110

    => 1v = 1-220

    => 1v = -120

    => v = -20 cm

    The image is formed on the same side as the object and since v is negative the image is erect and virtual and is formed at a distance 20 cm in front of the lens.

    We know that

    m = h1h0 = vu

    height of the object ho = 4 cm

    => h1 = v×h0u

    => h1 = -20×4-10

    => h1 = 8

    height of image = 8 cm

  • i think questions is : The sum of first six terms of an ap is 42 .the ratio of its 10th term is and its 30th term is 1:3. calculate the first and thirteenth term

    Posted by Naveen Sharma (Jan 18, 2017)
  • Add Comment
  • Answers:
  • Ans. 

    Let first term of AP is a and comman difference is d.

    as we know 

    an = a + (n-1) dwhere an is nth term

    => a10  = a + (10-1)d

    => a10  = a + 9d

    And a30 = a + (30-1)d

    => a30 = a + 29d

    According to Question

    => a+9da+29d = 13

    => 3a + 27d = a + 29d 

    => 2a = 2d

    => a = d       ............. (1)

    Sum of first 6 terms = 42

    We know 

    Sn = n2× 2a + (n-1)d

    =>S6 = 62 ×2a + (6-1)d

    => 42 = 32a + 5a

    => 42 = 21a

    => a = 2 

    First term is 2. Common difference is 2.

    => a13 = 2 + (13-1)2

    = > a13 = 2 + 24 

    =>  a13 = 26

Is india ready to go cashless

Posted by Mådihä Ušmån (Jan 17, 2017) (Question ID: 1421)

  • Answers:
  • India lacks infrastructure, which might be the biggest setback for a cashless system. Access to banking facilities and opening accounts has not reached the interior parts of India. In spite of Jan Dhan accounts being opened, most of the accounts seem non-operational. Lack of literacy about available banking facilities is a huge hindrance for such a system.

Which term of AP 121,117,113.................is its first negative term

Posted by Akash A.S (Jan 16, 2017) (Question ID: 1419)

  • Answers:
  • a = 121

    d = -4

    let an= 0

    then

    a= a + (n-1)d

    => 0 = 121 + (n-1)(-4)

    => 0 = 121 - 4n + 4

    => 4n = 125

    => n = 125/4

    => n = 31.25

    as n must be natural number then n= 32

    32nd term is First negative number.

    a32 = 121 + (31)-4

AB is a straight road leading to C,  the foot of a tower, A being at a distance of 120m from C and B being 75m nearer. If the angle of elevation of the tower at B is the double of the angle of elevation of the tower at A,  find the height of the tower. 

Posted by Shruti Sharma (Jan 16, 2017) (Question ID: 1415)

  • Answers:
  • Just consider the image for Reference. 

    Gievn : AB is straigt Road and C is the foot of tower. Let DC is tower of height h, and AC is 120cm and BC is 45 cm as it is 75cm nearer than A.

    Solution : In Triangle BCD 

    tan 60° = h45

    => h = 45 tan 2x  => h = 45 2tanx 1-tan2x   .............. (1) tan 2x = 2tan x1-tan2x

    In Triangle, ACD

    tan x = h120

    => h = 120 tan x       .................... (2)

    From (1) and (2)

    120 tanx = 45×2 tanx 1-tan2x

    => 1-tan2x = 34

    => tan2x = 14

    => tan x = 12

    Put value of tan x in (2)

    we get h = 60 

    so height of tower is 60cm

How do we come to know that which compound of carbon will make how much isomets and which rule do we follow while the making structure of an isomers?

Posted by Israr Khan (Jan 16, 2017) (Question ID: 1408)

  • Answers:
  • Isomerism is possible only with hydrocarbons having 4 or more carbon atoms, because only then we can have two or more different arrangements of carbon atoms. 

    No isomerism is possible in methane,ethane and propane because they contain only one,two or three carbon atoms respectively. Two isomers of the compound butane (C4H10) are possible and three isomers of compound pentane (C5H12) are possible. As the number of carbon atoms in an alkane molecule increases, the number of possible isomers increases rapidly.

Evolution in organism is beneficial but how 

Posted by Israr Khan (Jan 16, 2017) (Question ID: 1407)

  • Answers:
  • Evolution is good for life. Being able to adapt to the environment, as it is or if it changed, is how we ended here after all this millions or billions of years.

    Evolution is also not something that happens in the life of an individual, but through generations, and usually in a gradual way, specially to reach something that an arbitrary line said that it is a different species.

    And being the criteria for being sucessful, with evolution or without it (change always happen with enough time, be visible or not, but your species don't dissapear if is already very well adapted to the environment, just spawn different ones) is to live. What wasn't successful are species that weren't able to adapt or to evolve and end here in a way or another. Life is the evolution goal, not smarter, faster, stronger or nimbler, just survivor.

Why sun appears to be red in evening and morning?

Posted by Israr Khan (Jan 16, 2017) (Question ID: 1404)

  • Answers:
  • At the time of sunrise and sunset when the sun is near the horizon,the sunlight has to travel the greatest distance through the atmosphere to reach us. During this long journey of sunlight, most of the shorter wavelength blue-color present in it is scattered out and away from our line of sight. So,the light reaching us directly from the rising sun consists mainly of longer wavelength red color due to which the sun appears red. Thus,at sunrise and sunset,the sun itself as well as the surrounding sky appear red.

    Answered by Shweta Gulati (Jan 16, 2017)

  • During sunrise and sunset, the sun is at the farthest position. Here blue light gets scattered off and the red light, due to its larger wavelength, can travel a longer distance and hence reach our eyes. This we see the sun red.

Why does sperm produce in lower temp.than our body?

Posted by Israr Khan (Jan 16, 2017) (Question ID: 1395)

  • Answers:
  • There is a thing called 'maturing'. Sperms are not produced at the time of ejaculation. Actually it will be produced for days. After that they will mature gradually. This maturing process needs a very careful handling. This needs many essential things like vitamins,hormones,proper temperature range,etc. Within the body, temperature controlling is not advisable, because some organs need heat for their proper functioning. Especially for a male many of his organs work good in elevated temperatures. So, the body is having a convenient place to grow the sperms thereby the outside, where it can keep the required temperature without affecting the major organs.

    Heat is a factor that can cause great damage to DNA. In the testes where spermatogenesis (sperm meiosis) occurs you definitely do not want DNA damage occurring during or after this process as it could have devestating effects for the offspring. Hence, in a warm blooded human the testes are dropped from the body.

Give two examples of the use of supernatural in The Rime of Ancient Mariner?

Posted by Pratham Jain (Jan 15, 2017) (Question ID: 1386)

  • Answers:
  • The supernatural element is very prominent in the poem. The supernatural is evident from the very beginning of the poem. The main character, the ancient mariner with his ‘glittering eyes’ casts a spell on a wedding guest and compels him to listen to his story. Another example of the supernatural is the albatross, which the mariner encounters on his journey.

    The arrival of the albatross is hailed as a welcome sign, a good omen – a Christian soul. The killing of the albatross arouses the wrath of the supernatural spirits. The sailors believe the spirit of the albatross is following them and causing them agony. The sudden sinking of the ship, a skeleton ship and many other supernatural incidents are there in the poem.
