(i) I must use a freshly charged accumulator. 

(ii) I must take proper readings through my resistance box and potentiometer to avoid error due to parallax


(3bi)

Lost volt is the voltage lost due to the internal resistance of a cell.  It is measured in volts. 


(3bii)

E = I(R+r)

4 = I(2+0.5)

4 = 2.5I

I = 4/2.5

(1avi)

Slope(s) = Dy/DL =

y2 - y1/L2 - L1

Where y2 = 175g, y1 = 100g

L2 = 3.5cm, L1 = 2.00cm


Slope(s) = 175 - 100/3.5 - 2


(1avii)

(i)I ensured mass did not touch/rest on the table

(ii)I avoided error due to parallax on metre rule

(iii)I noted zero error on metre rule

(iv)I avoided draught

The principal of moments state 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


(1bii)

Draw the diagram 


Taking moments about point B ie CWM = ACM

(FA*7) = 10*2

7F = 20

7F/7 = 20/7

F = 2.9N
