WAEC GCE Physics Theory Answers for today:

No (1) (1)

They are used to determine the unit of a certain physical quantity in a specified unit system.

They are used to determine physical constants' or coefficients' dimensions.

They are used to translate physical quantities across different measurement systems (iii).

No (2a) (2a)

Time of flight: The amount of time needed for a projectile to return to the same level from whence it was launched is known as Time of Flight (T).

T = 2usin g

(2b) Maximum height: The maximum height (H) is the greatest vertical distance that can be reached when measured in relation to the projectile's horizontal path.

H = U2sin2/2g

(2c) Range: The horizontal distance from the point of projection to the point the projectile strikes the projection plane once more is known as Range(R).

R = U2sin2g

7a) No, magnetic materials are substances that are researched and employed primarily for their magnetic properties. The inherent angular momentum, or spin, of a material's electrons determines a major portion of the magnetic response of that material.

(5a) The forbidden gap is a collection of energy levels that are located between the conduction band and the valence band and cannot be inhabited by electrons.

Free electrons with negative charges (5b) I

Holes carry positive charges, so they are (ii)

by heating past the Curie point (7b) I

by using a powerful magnetic field.

No (9ai) Heat is a unit of measurement used to represent the passage of thermal energy between molecules in a system. Heat is a measure of energy flow. Temperature is measured in Celsius (°C), Kelvin (K), Fahrenheit (°F), or Rankine and refers to the average kinetic energy of molecules inside a substance or system (R).

(9aii) The temperature of pure melting ice at standard atmospheric pressure is known as the lower fixed point, or ice point. While the temperature of pure boiling water at standard atmospheric pressure is the top fixed point.

9c. The fractional increase in length of a solid specimen per unit change in temperature is known as linear expansivity. The expansivity () is given by l2 = l1(1 + ) if a specimen lengthens from l1 to l2 when its temperature is elevated by °. *PHYSICS*

(10bi) The superposition principle states that the displacement at a point where two or more waves intersect is equal to the sum of the displacements of the individual waves. The displacements of the various waves can be either positive or negative. If the displacements are vectors, vector addition is used to get the sum.

(10c) Refraction is wavelength dependent. Blue light refracts more than red because its wavelength is shorter while traveling from the atmosphere to glass.

No (11ai) Reactance is a circuit element's resistance to current flow as a result of that element's inductance or capacitance.

(11) Impedance is a measurement of the resistance to alternating current flow across a circuit (11aii).

(8ai) When a body is pushed by a force over a predetermined distance in the force's direction, which is equal to the product of the force and the distance traveled, it is said to have performed work.

(8aii) Workdoned: Force times Distance

= F*S

F = m(v/t)

Work completed = m(v/t) * 1/2vt

= 1/2mv²

Ek = 1/2mv²

work completed = change in the body's kinetic energy


A body must overcome kinetic friction in order to move across another body at a constant speed.


1) The nature of the surfaces in touch

(ii)Relies on the usual force that presses the surfaces together.


Tc = umg + ma

Tc – (0.3 * 3* 10)= 3*2

Tc – 9 = 6

Tc = 9+6 = 15N


2umg - TB = ma

TB – 2(9)= 3*2

TB = 6+18

TB = 24N


TA = ma - 3umg

TA – 3(9) = 3*2

TA – 27 = 6

TA = 6+27

TA = 33N
