Physic - 1
This shall be my Science online journal from now on(:Presentations were done by most of my classmates during science lessons on Thursday and the week before. These are the things that I have gathered. Topic 1: To appreciated our limited water source, you're given a map that shows MacRitchie Reservoir. How do you estimate the volume of water available during the dry season when the average depth of the water is 2.5m?  There are 2 solutions to this question: Solution 1: Area of cuboid = Length x Breadth x Height 1cm --- 60 000cm Depth: 250cm Length: 120 000cm Breadth: 84 000cm 250 x 120000 x 84000 = 2520000000000 cm³ = 2520000000000ml = 25.2 giga ml Solution 2: Area of cylinder: π x radius x radius x height radius : 125cm height : 15000cm π : 3.14 3.14 x 125 x 125 x 15000 =7359375 thousand ml ------------------------------------------------------------------------------------------ The working to this question is really tough and tedious. However, if we compare these two methods to the 'tick' method, I would definitely use the above ones(: What I have learnt: Science aren't just science only. Sometimes we use math in science too. Sometimes the other way round too(: will continue my next post. |
