1v)
1vii) - i will ensure that no external force is added to the system
-i will ensure that no pallarax error in taking the readings of the stop watch

1bi) Period of oscillation of a simple pendulum is the the taking the pendulum to complete one oscillation
1bii) NaA=15 NB=20 TA=1.5sec
But TA= tA/NA tA =Ta*Na =1.5*15 TA=22.5sec
The Tb= tB/Nb But tA=tB=22.5sec Tb=22.5/20 =1.125sec

3vi) S=AB/BC= 0.0225-0.01/1200-400 =0.0125/800 =1.5626*10^-5
3vii) - i will ensure that there are no partial connections - i will ensure that the key is removed after each reading.

3bi) 1= red light has higher wavelenght than violet light
2= red light has lower energy than violet light
3bii) E=h c/n E= 6.6*10^-34 * 3*10^8/700*10^-9 = 2.83*10^-19 j
3biii) - cross sectional area - length - temperature.
