The advantage of specializing is that it improves efficiency and also increases production because people get more skilled in that specific area. Therefore, the cost of products would start to fall and there is...

    Physics (0625) formula sheet

    Acceleration due to gravity is also the same; acceleration of a freefalling object is 10m/s^2 and the force of gravity on earth is 10N/kg. I also learn it as force of gravity but this doesnt mean he is incorrect.

    Physics, Chemistry and Biology: Post your doubts here!

    From the diagram, it appears that the metal case does not go back to the beginning so that means current wouldn't flow after it reaches the cable so its not a full circuit. Ofcourse, u can argue otherwise however u must remember that CIE is looking for the "most suitable answer" so the most...

    Potassium Manganate is a oxidising agent therefore is reduced itself. As alkenes are unsaturated, they are able to react with the MnO4 ion and that is why it turns colourless
