    At first, i made diagonal lines to show the 'darker regions'. Our teacher said your not suppose to shade, but can make lines to distinguish the areas. Then i peeked at my friends paper and decided to rub them.:) What would one do without cheating?

    New here PLZ HLP ME OUT!!!!!!!!

    The answer is A, 2.5J. 1/2 kx2......where k is the gradient. so 0.20/25 = 0.008(this is the spring constant). Then just put it in the equation. 1/2x(0.008)x25x25=2.5J let me see the other question

    HOW WAS BIOLOGY PAPER 3 PRACTICALS?

    Re: HOW WAS BIOLOGY PAPER 33? Yes, like i said it was a pretty straight forward table. One column for Solution and one for Time taken in seconds. I made two extra columns but they weren't necessary as you were asked the volume of each solution in the last page. My time for Sample was 45s...

    HOW WAS BIOLOGY PAPER 3 PRACTICALS?

    Re: HOW WAS BIOLOGY PAPER 33? Yes it is. I also added two columns for "volume of solution" and "volume of benedicts added". But considering that 4 marks are for your observations, your table your measurements and the accuracy then just time was enough. And yes it was an Artery and a Vein.
