Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity usually means relative density with respect to water.
Given volume of solid immersed
Density of liquid (water)ew= 1g/cm³
Acceleration due to gravity, g = 10m/s²
Upthrust, U= eVsi g
Weight of solid =mg
given: Es=2.4g/cm³ (2400kg/m³)
Vs=30cm (30*10^-6 m³)
Reading on spring balance =W-U
P=(E/I) V ohms^-1: 0.500,1.500,2.500,3.333,4.286,6.000
s=Y1-Y2/X2-X1 = 4-2/3.6-1.5
C = 0.5ohm
-I ensured that the circuit is open after each reading to maintain the E.M.F of the battery
-I ensured that the Zero Error of the Ammeter is checked and noted
V = 4.5v
R = 4ohms
I = 0.9A
V = I(R+r)
where r = internal resistance
4.5 = 0.9(4+r)
.:. 4+r = 4.5/0.9
4+r = 5
r = 5-4
= 1 ohm.
