  1. Pressure is not spelled 'pressure'

    1. Then what it is spelled as ???
      If it is not spelled 'pressure'

  2. whats dyne?? i only know newton

    1. unit for force haaa............

    2. Unit of force is newton.{Q4}

    3. it is unit of force
      1 newton = 100000 dyne
      dyne is a unit of force specified in the centimetre–gram–second system of units (CGS), a predecessor of the modern SI.

    4. We can convert newton to kg etc.

  3. Expecting more MCQs for this lesson

  5. i also got full the questions are so easy

  6. the 4 answer is wrong.. it is newton. checked in google. please refer another web page also.

    1. In MKS systems and SI units, unit of force is Newton. In CGS system, it is dyne. Another unit used earlier to measure weights (a type of force) is kg-wt (1 kg-wt = 9.8N). Option 'd' is correct.

  7. The SI unit of force is the newton,i checkout it on google and google is always right

  8. Requesting 2 more mcq because have to do 12 in science notebook😂

  9. Good questions but then it will be good if we get more tuff questions.


We love to hear your thoughts about this post!
