(1) tables of values sn:1,2,3,4,5 x (cm):10.0,15.0,20.0,25.0,30.0 Jk=y (cm) :70.60,68.10,65.50,62.80,60.30 y^-1(cm):67.2,65.5,63.4,61.1,59.0 p=y- y^-1(cm) :3.400,2.600,2.100,1.700,1.300 (1bi) moment is the turning effect of forces about a point or axis. e.g rotation of wheels of vehicles. the unit is Nm and it is a vector quantity principle of moments states that if a body is in equilibrium, then the sum of the clockwise moments about any point on the body is equal to the sum of the anticlockwise moments about the same point precaution: (i)i ensured that m1 is completely immersed in water (ii)i ensure that parallax error is avoided when taking readings (1biii) weight in air air=0.25 weight in water=0.15 upthrust=0.25-0.15=0.10 relative denstity= weight in air/ weight in water relative density= 0.25/0.10 =2.5 (3) tables of value sn:1,2,3,4,5,6 I/ A:0.1,0.2,0.3,0.4.0.5,0.6, V/ V:0.50,1.50,2.00,2.30,2.50,3.00 I/I^-1/ A^-1:10.000,5.000,3.333,2.000,1.667 V^-1/ V^-1:2.000,0.667,0.500,0.400,0.333 (3 continues) precautions: -i ensured tight connection -i ensured error due to parallax when taking reading from the voltmeter (3bi) Ammeter: -it is used for measuring current -it is denoted by A voltmeter: -it is for measuring voltage -it is denoted by V GOODLUCK!!
