Stay calm while you wait for it.

(3viii)
Slope, S = ΔZ/ΔR-¹
S = (0.84 – 1.28)/(0.6 – 0.29)
S = -0.44/0.31
S = -1.419
Intercept, c = 1.68
(3ix)
K = c-¹ = (1.68)-¹
K = 0.595
(3x)
(i) I avoided parallex error when reading the potentiometer
(ii) I ensured tight connections
(3bi)
A possible reason is wrong circuit connection
Solution: Check connections and ensure they are all tight.
(3bii)
I – Voltage
II – Current.

(1bii)
Weight in Air = 2.9N
Weight in water= 1.3N
Relative Density= ?
Relative Density = Weight in Air/ Change in weight of water
R.D = 2.9/(2.9 – 1.3)
= 2.9/1.6 = 1.8125
Relative Density = 1.813 = 1.813
