Filed in Education on February 16, 2021

WAEC GCE Physics Practical Questions: After WAEC GCE Physics OBJ and essay exam is written, students are expected to participate in the practical examination. Physics Practical WAEC GCE expo questions are out now on our website.

In this article, I will be showing you past WAEC GCE Physics Practical random repeated questions for free. You will get to understand how the questions are set and many more examination details. Read on to see more details below.

The West African Examinations Council (WAEC) is an examination board that conducts the West African Senior School Certificate Examination, for University and Jamb entry examination in West Africa countries. In a year, over three million candidates registered for the exams coordinated by WAEC.

We made this post to highlight samples of the Specimens, alternative to practical graphs and calculations that were used in the Practical Examination past questions and syllabus.

WAEC GCE Physics Practical Questions and Answers 2021

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.

(1bii)

Vsi =1/2*30cm³

=15cm³

Density of liquid (water)ew= 1g/cm³

Acceleration due to gravity, g = 10m/s²

Upthrust, U= eVsi g

U= 1000*(15*10^-6)*10

U=15*10-²

U=0.15N

Weight of solid =mg

=EsVs g

given: Es=2.4g/cm³ (2400kg/m³)

Vs=30cm (30*10^-6 m³)

g=10m/s²

Weight, w=30*10^-6*2400*10

=72*10-²

=0.72N

=0.72-0.15

=0.57N

===============================

(3aiv)

Tabulate pls:

S/n: 1,2,3,4,5,6

R/ohms: 0.00,1.00,2.00,3.00,4.00,5.00

I/A: 3.00,1.00,0.60,0.45,0.35,0.25

P=(E/I) V ohms^-1: 0.500,1.500,2.500,3.333,4.286,6.000

(3vi)

s=Y1-Y2/X2-X1 = 4-2/3.6-1.5

=2/2.1

=0.952

(3vii)

C = 0.5ohm

(3viii)

Resistance

(3ix)

-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

(3bii)

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.
