    Its like when a tyre is pushed down a cliff, when it reaches the bottom of the cliff, It will have the greatest Kinetic Energy even though there is no steep road ahead of it . Same goes for the coil. You can assume that tyre on the bottom of the cliff is Coil at horizontal position. OMG I cant...

    The Clockwise/AntiClockwise you're referring to are MOMENTS, He has already asked for resultant moment in the previous part. When he asks for force, you may forget that theres a pivot and the object can rotate etc etc. You have to remember that since these FORCES are opposite in direction, you...

    Over here he asks the RESULTANT FORCE on the OBJECT soo As 500N downward force and 400N upward force therefore resultant will be 500N-400N= 100N Downward force

    Yes, In the book you can find it under the topic of Temperature/Thermometers This is used when you have a thermometer in which only ice point and steam point are marked and you are given the length of the of the mercury expansion. Temperature= (Length At Unknown temperature - Length at Ice...

    British Council is jealous of my sweets >:^(

    My friend once sneaked in a packet of lays inside the exam hall, ate it during the time that we have to wait before the exam. He made the invigilators really angry later when he asked one of them 'Where can I find the dustbin?' Since then he is the supplier of bubblegum for our class during exam...

    I wrote add zinc to both the solutions of acids, zinc will react with the stronger acid but will not/slowly react with the weaker acid

    I don't even remember xD . It said describe an experiment to show that HCl is a stronger acid then Ethanoic Acid

    Chemistry MAY/JUNE 2017 - P 22

    In the energy diagram i forgot to label progress of reaction. I attempted the question with the Reversible reaction. In the second last part, about speed of reaction with weak/strong acid, I doubt they'll give me full marks (idk it was of 2/3 marks). I did the last part wrong (name 2 salts) 1 mark.
