NECO Physics Essay Answers 2026/2027

(1a)
(i) Armature (soft iron core wound with insulated copper wire)
(ii) Field magnet (permanent magnet or electromagnet)

(1b)
A flat plate collector absorbs both direct and diffuse solar radiation over its full surface area without concentrating it, and is used mainly for low-temperature applications like water heating. WHILE A focusing (concentrating) collector uses mirrors or lenses to concentrate sunlight onto a small receiver area, producing much higher temperatures, but can only make use of direct radiation and must track the sun.

(1c)
Magnifying power of microscope = Magnification of objective × Magnification of eyepiece
20 = 4 × M(eyepiece)
M(eyepiece) = 20/4 = 5

NUMBER 3
(3a)
T = 2π√(L/g)

(3b)
ω = 0.5π rad/s
T = 2π/ω = 2π/(0.5π)
T = 4 s

(4a)
Taking P’s direction as positive:
u(P) = 30 ms⁻¹, u(Q) = −15 ms⁻¹ (opposite direction), m(Q) = 10 kg, common final velocity v = 25 ms⁻¹

By conservation of momentum:
m(P)u(P) + m(Q)u(Q) = (m(P) + m(Q))v
30m(P) + 10(−15) = (m(P) + 10)(25)
30m(P) − 150 = 25m(P) + 250
5m(P) = 400
m(P) = 80 kg

(4b)
It is an inelastic collision (specifically a perfectly inelastic collision, since kinetic energy is not conserved and both bodies move with the same final velocity after collision).

(5a)
(i)Inclined plane
(ii) Pulley

(5b)
Potential energy is the energy possessed by a body due to its position or state, while kinetic energy is the energy possessed by a body due to its motion.

(6a)
(i) Ultraviolet rays
(ii) X-rays

(6b)
Mechanical waves require a material medium to travel through, whereas electromagnetic waves do not require any material medium and can travel through a vacuum.

(7)
f = 50 Hz, v₁ = 1.0 ms⁻¹, v₂ = 0.4 ms⁻¹
λ = v/f
λ₁ = 1.0/50 = 0.02 m
λ₂ = 0.4/50 = 0.008 m
Difference = λ₁ − λ₂ = 0.02 − 0.008
Δλ = 0.012 m

(9)
G = 5 Ω, Ig = 20 mA = 0.02 A, I = 10 A
Current through shunt: I − Ig = 10 − 0.02 = 9.98 A
Since galvanometer and shunt are in parallel, voltage across both is equal:
Ig × G = (I − Ig) × S
0.02 × 5 = 9.98 × S
0.1 = 9.98S
S = 0.1/9.98 ≈ 0.01 Ω

(8a)
It means that a body/object must be projected from the Earth’s surface with a minimum velocity of 11 km/s in order to completely overcome (escape) the Earth’s gravitational pull and never return, without any further propulsion.

(8b)
The lead-acid accumulator is a secondary cell and can be recharged repeatedly for continued use, whereas the wet Leclanché cell is a primary cell and cannot be recharged once its chemicals are used up.

(11a)
(i) A photoemissive cathode (light-sensitive surface/electrode)
(ii) An anode (collector electrode), both enclosed in an evacuated glass or quartz tube

(11b)
Given: Ve = h/(Meλe)
Kinetic energy, KE = ½Me·Ve²
KE = ½Me × [h/(Meλe)]²
KE = ½Me × h²/(Me²λe²)
KE = h²/(2Meλe²)

(12a)
The principle of floatation states that a floating body displaces its own weight of the fluid in which it floats.

(12b)
A cone resting on its base has a large surface area of contact and a low center of gravity relative to its base, making it stable when slightly tilted, it returns to its original position. WHILE A cone resting on its apex has a very small area of contact and its center of gravity lies high above the point of support, making it unstable when slightly tilted, it topples over instead of returning to its original position.

(12c)
F = ma = M(v − u)/t
Making M the subject:
M = Ft/(v − u)

(12di)
T = 2.0 s
f = 1/T = 1/2.0
f = 0.5 Hz

(12dii)
m = 400 g = 0.4 kg
T = 2π√(m/k) → k = 4π²m/T²
k = (4 × 3.14² × 0.4) / (2.0)²
k = (4 × 9.8596 × 0.4) / 4
k = 15.775 / 4
k ≈ 3.94 N/m

(13a)
A claw hammer is termed a first-class lever because, when removing a nail, the fulcrum (the curved part of the hammer head resting against the wood) is positioned between the effort (applied by hand at the end of the handle) and the load (the resistance of the nail being pulled) the same arrangement (Load–Fulcrum–Effort) as a first-class lever.

(13bi)
It is not advisable to sterilize a clinical thermometer in boiling water because a clinical thermometer has a narrow temperature range (usually 35°C to 43°C) designed only to measure human body temperature. Boiling water is at 100°C, which is far above this range the mercury would expand beyond the bulb’s calibrated limit, building up excess pressure and causing the thermometer to crack or burst.

Given:
Copper ball: mc = 50 g = 0.05 kg, initial temp = 120°C
Water: mw = 100 g = 0.1 kg
Copper calorimeter: m_cal = 80 g = 0.08 kg
Final mixture temperature = 30°C
c(water) = 4.2 × 10³ Jkg⁻¹K⁻¹; c(copper) = 4.0 × 10² Jkg⁻¹K⁻¹
Heat lost by copper ball (cooling from 120°C to 30°C):
Q(lost) = mc × c(copper) × ΔT
Q(lost) = 0.05 × 400 × (120 − 30)
Q(lost) = 0.05 × 400 × 90 = 1800 J
Heat gained by water + calorimeter (heating from initial temp Tw to 30°C):
Q(gained) = [mw·c(water) + m_cal·c(copper)] × (30 − Tw)
Q(gained) = [(0.1 × 4200) + (0.08 × 400)] × (30 − Tw)
Q(gained) = [420 + 32] × (30 − Tw)
Q(gained) = 452 × (30 − Tw)
Equating heat lost = heat gained:
1800 = 452 × (30 − Tw)
30 − Tw = 1800/452 = 3.98
Tw = 30 − 3.98
Tw ≈ 26.0°C

A wavefront is an imaginary surface (or line) joining all points of a wave that are in the same phase of vibration at a given instant.

(14bi)
I: Searchlight produces a parallel beam of light (rays travel in straight lines parallel to one another).
II: Bulb (point source) produces a divergent beam of light (rays spread outward from a single point).

(14bii)
In regular reflection, parallel rays of light falling on a smooth, polished surface (e.g., a plane mirror) are reflected as parallel rays in one definite direction. WHILE In diffuse reflection, parallel rays falling on a rough surface are reflected in many different, scattered directions because the surface irregularities cause the normal at each point to point differently.

Fundamental frequency: f₁ = v/λ = 340/2.0 = 85 Hz:
f₁ = v/λ = 340 ms⁻¹ / 2.0 m = 170 Hz
For a closed pipe, only odd harmonics exist. The first overtone = 3rd harmonic = 3f₁
First overtone = 3 × 170
First overtone = 510 Hz

Combined resistance of the parallel resistors (2Ω and 5Ω):
1/R = 1/2 + 1/5
1/R = 5/10 + 2/10 = 7/10
R(parallel) = 10/7 ≈ 1.43 Ω

(15cii)
Total current in the circuit:
Total resistance = internal resistance + series resistor + parallel combination
R(total) = 0.5 + 4 + 1.43
R(total) = 5.93 Ω
Using I = E/R(total):
I = 2/5.93
I ≈ 0.34 A

(17a)
A continuity tester is used to check whether an electrical circuit, wire, or component is complete (unbroken) it shows if current can flow through a conductor from one end to the other, helping detect breaks, cuts, or faults in wiring, fuses, or switches.

(17b)
(i) A wheelbarrow (lever) used to move goods on a construction site.
(ii)An inclined plane (ramp) used to load heavy goods/drums onto a truck.

(17c)
A prism uses total internal reflection, which reflects all the light falling on it with no loss of intensity and no silvering to wear off or tarnish, giving a brighter, clearer, single image a mirror, on the other hand, loses some light through absorption by its silvered coating and can produce faint multiple (ghost) images.

Magnification = Image size / Object size = 110 cm / 10 cm
Magnification, m = 11

Since m = v/u, and v (image distance) = 100 cm:
u = v/m = 100/11
Object distance, u ≈ 9.09 cm
