(1)
Range|PQ| = U²Sin2Θ/g
Where U = 250ms-¹, Θ= 42°
= 250²×Sin(2×42°)/10
= 62,500×Sin84°/10
= 6250×0.9945
= 6215.63m


(2)
(i)They are pure semiconductors with impurities less than 1 and have tetravalent cystals
(ii)Presense of mobile charge carrier is intrinsic property of material
(iii)No doping or addition of impurities required.


(4)
F=50N, K=100N/m
F= ke ==> 50-100e
e= 50/100
= 0.5m

Workdone = 1/2ke²


=1/2 x 100 x 0.5²
=25/2
=12.5joules(5a)
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800km directly over the equator, that revolves in the same direction which the earth rotates.

WAEC Physics Syllabus 2022/2023

PREAMBLE: The syllabus is evolved from the Senior Secondary School teaching syllabus and is intended to indicate the scope of the course for the Physics examination.

It is structured with the conceptual approach.  The broad concepts of matter, position, motion and time; energy; waves; fields; Atomic and Nuclear Physics, electronics are considered and each concept forms a part on which other sub-concepts are further based.

AIMS: The aims of the syllabus are to enable candidates

  • acquire proper understanding of the basic principles and applications of Physics;
  • develop scientific skills and attitudes as pre-requisites for further scientific activities;
  • recognize the usefulness, and limitations of the scientific method to appreciate its applicability ion other disciplines and in every life;
  • develop abilities, attitudes, and skills that encourage efficient and safe practice;
  • develop scientific attitudes such as accuracy, precision, objectivity, integrity, initiative, and inventiveness.

 

SCHEME OF EXAMINATION: There will be three papers, Papers 1, 2, and 3, all of which must be taken. Papers 1 and 2 will be a composite paper to be taken at one sitting.
