First question
Connect the sides with crosses
The centre of mass was 4.3 cm ( 43mm) there is range
Any use of fidicual aid
Second question
27 Celcius
Temperature fall was 18 first and second was 1
Plot points and draw best fit curve
The temperature fall at first is higher than for last mintue
The gradient is greater than last mintue
Third question
Calulate resistance by formula R=V/I ( ROUNDED to 2 or 3 signifact figures )
Complete headings of table( V, A, ohms)
Calculate sum of resistances mentioned above ( addittion only). It is was 11.43
Draw the circuit draigram
Calulate the resistence by R=V/I. It was 8.93
The statement is NO because it was out of limits of accuracy and precentage of error was 27.3
The temperature changes, the resistense changes, varying currnet
Fourth question
DRAWING is below
Angle of incidence is 21 and angle of reflection is 20
Sources of error were parallex error, thickness of mirror, thickness of pins
Fiffth question
The keyboard was 0.07
The current is 0.25
The coffee cup is 100
Circufmence of beaker is 23
There scan picture of all diagrams
