    Sir muj ku phy ka 1stch ka nots send hak day plzzzzzzzzzz.

  8. sara shy says:

    kindly plz update the solutiobn of ch: 6,7,8

  9. Raja says:

    Any solution for the exercise questions of Physics 9th Punjab Board – Practical Notebook? Would be great if you can post.

    Thanks for all the above chapters anyways!

  10. saba says:

    chappp 8 numericalsssss????? plxxxxxxx plxxxxxx

  11. mehrre says:

    plzzz 6 7 nd 8 k nots de do admin

  12. Maryum Rafique says:

    the tension will be 10 N. .. . . Action and reaction Are equal and opposite.take a string hold into your vertically tension will be 0. Beacuse theres no reaction to make the string tight. Now suspend a string froma stand tie 10kg force on its lower.. Now tell what will be tension. Yes ur right 10 N. stand is apPlying 10 N force to hold the weight. now your own inspection

  13. Aminah says:

    Aoa. My question is related to chap #9:
    Why does the thermal conductivity of a substance change by change in LENGTH?
    Does it not have a fixed value for e.g thermal conductivity of air is ALWAYS 0.026?

  14. Afaq says:

    chap 7 numerical 7.6 solved

  15. Afaq says:

    what is tension in a string?

  16. usama iqbal says:

    plzzzzzzz send mcqs of chapter 3 physics of 9th class

  17. usama iqbal says:

    a string is stretched by two equal and opposite forces 10 N each. the tension in the string is?

  18. jalal khan says:

    plz chapters 6,7,8 k notes bhej dai.

  19. huma says:

    if a body has no acceleration does it mean that no force acting on it?

  20. huma says:

    resning question plz sent me sir…………………

  21. zafar says:

    i need short questions and numerical of chapters 6,7,8

  22. fahad says:

    what is tension??

  23. muqadas says:

    sir kindly give me the solution of chp 6,7 & 8

  24. muqadas says:

    sir how can i open the solution of chp 6

  25. fatima says:

    i need solved numericals of chapter no 8 plz ri8 now

  26. ayesha says:

    assalamo allaikum… help me with the following questions…
    1. why rolling friction is less than sliding friction?
    2. how a ceiling fan satisfy 2nd condition of equilibrium when rotating with uniform speed?
    3. how a washing machine dryer works?
    4. what is the net tension on a rope when it is pulled with 10 newton force at each end?
    5. newtons 1st law is valid in the absence of?
    ……………………..kindly help me with this by giving a quick response … THANK YOU

    • admin says:

      1. Rolling friction is less because of the less surface area contact.

      2. A celling fan rotating with constant speed satisfies 2nd condition of equilibrium because of the constant angular speed and in this case the sum of all torques is zero.

      3.The spin dryer of a washing machine removes excess water from the clothing by rotating at a high speed. The high speed of rotation creates a high centrifugal force for the water in the clothing which causes it to be pulled to the outside of the spinning portion of the washing machine and away from the clothes.

      4. 20 N.

      5. In the absence of net external forces.

  27. abdurrab says:

    i want to draw a graph between 2S and t^2 . But I donot know how a scale is selected??????

    • admin says:

      You can select your own scale for example 1 big box is equal to 10 and 1 small box is equal to 1. The scale of x and y axis can be different.

  28. Manno says:

    chapte 6,7,8 numaricalx plz show

  42. soni says:

    chap 6,7 n 8 k numerical kab milyn gy??????????

  43. sajid kazmi says:

    if a string is pulled by both sides with 10N force then tension in string will be: 0 or 20N give reason please

  44. Faruu Zaib says:

    second thing sir i want solved chapter. no 12 and 16 of maths (quickly) because. exams are drawing near!.

  45. Faruu Zaib says:

    Respected sir! i want to ask from you that is fire an example of plasma( the fourth state of matter) ?

    • admin says:

      It can be, because fire is the mixture of various hot gases and if the flame is hot enough to ionize the gases than it becomes plasma.

  46. Javeria Sher says:

    we want numericals of other chapters as quick as possible plz upload them

  47. Mohammad Talha says:

    Admin Plzz…. Remaining Chaps ke b notes upload ker den .. …
