একজন ছাত্র পরীক্ষাগারে অভিকর্ষজ ত্বরণের মান 9.88 m/sec2 নির্ণয় করন। অপর দিকে যখন সে 0.01 kg ভরের কোনো বাটখারাকে স্প্রিং নিক্তিতে ঝুলিয়ে দিল তখন 0.0980 N বল দেখাচ্ছে। তার পরীক্ষা অভিকর্ষজ ত্বরণের ত্রুটি নির্ণয় কর।(A student measured the value of acceleration due to gravity in the laboratory as 9.88 m/sec2. On the other hand, when he hanged a mass of 0.01 kg in the spring balance, then he found 0.0980 N force. Calculate the percentage of error in the measured value of the acceleration due to gravity.)

The distillation carried out in such a way that the liquid with the lowest boiling point is first evaporated and re-condensed, then the liquid with the next higher boiling point is then evaporated and re-condensed, and so on until all the available liquid fuels are separately recovered in the sequence of their boiling points. Such a process is called
