  • Answers:
  • Osmosis is a phenomenon where in there happens to be  a movement of solvent particles ( ie. molecules  / ion )  from a solution  of lower concentration  to that of higher concentration when the two are separated from each other by a semipermeable membrane.

    while , 

    Osmotic pressure  is the pressure built up between the two solution undergoing osmosis . It is  caused due to a difference of vapour pressures  between  both the solutions.

  • Answers:
  • The power rating of equipment is defined as the highest power input allowed to flow through particular equipment. According to the particular discipline, the term "power" may refer to the electrical or mechanical power.

    A 60 Watt 220V bulb means that it will consume 60 Watts when the voltage across it is 220V.

Find the quadratic polynomial ,the sum of whose roots is √2 and their product is 1/3

  • Answers:
  • Let the roots of quadratic equation be {tex}\alpha{/tex} and {tex}\beta{/tex}.

    Then Sum of roots = {tex}\alpha{/tex} + {tex}\beta{/tex} = {tex}\sqrt 2 {/tex}

    =>     {tex}{b \over a} = {{\sqrt 2 } \over 1}{/tex}

    =>     {tex}{-b \over a} = {{\sqrt 2 } \over 1} \times {3 \over 3}{/tex}     =>     {tex}{-b \over a} = {{3\sqrt 2 } \over 3}{/tex}               ..............(i)

    And, Product of roots = {tex}\alpha{/tex}.{tex}\beta{/tex} = {tex}{1 \over 3}{/tex}

    =>     {tex}{c \over a} = {1 \over 3}{/tex}          ................(ii)

    On comparing both the equations, we have

    {tex}a = 3,b = - 3\sqrt 2 ,c = 1{/tex}

    Putting these values in the general quadratic equaiton {tex}a{x^2} + bx + c = 0{/tex}, we get

    {tex}3{x^2} - 3\sqrt 2 x + 1 = 0{/tex}

Use Euclid's division algorithm to find the HCF 27727 and 53124

  • Answers:
  • we take 53124 as the dividend and 27727 as the divisor

    by Euclid's  Div Lemma

    53124 = (27727 x 1) + 25397

    now we take 27727 as dividend and 25397 as the divisor

    27727 = (25397 x 1 ) + 2330

    now we take 25397 as dividend and 2330 as the divisor

    25397  = (2330 x 10) + 2097

    now we take 2330 as the dividend and 2097 as the divisor

    2330 = (2097 x 1) + 233

    now we take 2097 as the dividend and 233 as the divisor

    2097 = (233 x 9 ) + 0

    Hence the HCF of 27727 and 53124 is 233

  •    53124 = 27727 x 1 + 25397

    =>     27727 = 25397 x 1 + 2330

    =>     25397 = 2330 x 10 + 2097

    =>       2330 = 2097 x 1 + 233

    =>       2097 = 233 x 9 + 0

    Since on finding remainder 0, we have the divisor 233.

    Therefore, H.C.F.(53124, 27727) = 233

  • Answers:
  • Root pressure is the positive hydrostatic pressure that develops in the roots and helps in the movement of water up the xylem in plants. It develops when the minerals are actively absorbed by root hairs called active transport.

    This active transport of minerals inside the root cells creates concentration gradient between soil and root cells i.e inside root cells solution become concentrated as compared to soil. The water rushes inside the roots from soil that creates pressure in roots called root pressure.

    Dear Diary,

    I just had a long argument with my parents today. They just don’t understand my point of view. My friend, Radhika wants to host a party at the club next weekend. It will end late, around 11 pm. I really want to go, but my parents feel it is an inappropriate time for the party to end. I told  them not to worry, but they just don’t understand how important this is to me.
    Why do they not understand that I can take care of myself ? I understand that they are concerned about my safety, but I wish I had more freedom. They do not like  long chats with my friends on my phone. Everyone chats on phones these days. Why should I be stopped ?
    I feel that it is nobody’s fault ; it is the generation gap between my parents and me. They are from a different time and are unaware of how children are today. I have to talk to them tomorrow about my feelings and how I need my freedom. I love them and respect them, and I hope they understand how I feel.  Let's see how it goes ; will let you know tomorrow.

  • B) Increase

    Explanation : When you add pure water to an acidic solution, the solution becomes less acidic and the pH goes up -- to a point. For example, if you add pure water to a relatively acidic solution that has a pH of 3.5, the pH level might go up to a 4 or 5. You cannot, though, turn an acidic solution into a base solution or make it neutral just by adding water. As a result, pure water can only raise the pH of an acidic solution to a maximum of a 6.9.
