  1. Question 1 · UTME 2024 · Motion

    When a bus is accelerating, it must be

    1. Achanging its speed
    2. Bchanging its velocity
    3. Cchanging its position
    4. Dchanging its direction
    Show answer and solution

    Answer: B. changing its velocity

    What the question is asking: What does acceleration always mean?

    Key idea: Acceleration is the rate of change of velocity. The velocity may change in size (speed), direction, or both — so 'changing its velocity' is the only statement that must be true.

  2. Question 2 · UTME 2024 · Refraction of Light Through Plane and Curved Surfaces

    Calculate the real depth of a swimming pool if its apparent depth is 10 cm. [refractive index of water = 1.33]

    1. A7.5 cm
    2. B10.0 cm
    3. C13.3 cm
    4. D6.87 cm
    Show answer and solution

    Answer: C. 13.3 cm

    What the question is asking: Real depth = n × apparent depth.

    Step 1 – 1.33 × 10 = 13.3 cm

  3. Question 3 · UTME 2024 · Work, Energy and Power

    The energy of a moving car due to its motion is

    1. Aelectrical energy
    2. Bchemical energy
    3. Cpotential energy
    4. Dkinetic energy
    Show answer and solution

    Answer: D. kinetic energy

    What the question is asking: Energy due to motion.

    Key idea: Kinetic energy = ½mv², the energy a body has because it is moving.

  4. Question 4 · UTME 2024 · Reflection of Light at Plane and Curved Surfaces

    Which of the following is best used as a shaving mirror?

    1. Aconcave mirror
    2. Bconvex mirror
    3. Cplane mirror
    4. Dcylindrical mirror
    Show answer and solution

    Answer: A. concave mirror

    What the question is asking: Which mirror magnifies the face?

    Key idea: With the face inside its focal length, a concave mirror gives an upright, magnified, virtual image.

  5. Question 5 · UTME 2024 · Quantity of Heat

    How much heat is given out when a piece of iron of mass 60 g and specific heat capacity 460 J kg⁻¹ K⁻¹ cools from 75 °C to 35 °C?

    1. A1000 J
    2. B1050 J
    3. C1067 J
    4. D1104 J
    Show answer and solution

    Answer: D. 1104 J

    What the question is asking: Q = mcΔθ

    Step 1 – Q = 0.06 × 460 × 40 = 1104 J

  6. Question 6 · UTME 2024 · Elementary Modern Physics – Bohr's Theory

    An electron falls from an energy level of −5.44 eV to another level E, emitting a photon of wavelength 5.68 × 10⁻⁶ m. Calculate the energy change. [h = 6.63 × 10⁻³⁴ J s, c = 3.0 × 10⁸ m s⁻¹]

    1. A1.49 × 10⁻²⁰ J
    2. B1.49 × 10⁻¹⁹ J
    3. C3.49 × 10⁻²⁰ J
    4. D3.49 × 10⁻¹⁹ J
    Show answer and solution

    Answer: C. 3.49 × 10⁻²⁰ J

    What the question is asking: Energy change = photon energy hc/λ.

    Step 1 – E = 6.63 × 10⁻³⁴ × 3.0 × 10⁸/5.68 × 10⁻⁶

    Step 2 – E ≈ 3.50 × 10⁻²⁰ J (≈ 3.49 × 10⁻²⁰ J)

  7. Question 7 · UTME 2024 · Dispersion of Light and Colours

    A red shirt seen under red light appears red because it

    1. Areflects nearly all the light falling on it
    2. Bis unable to reflect the light falling on it
    3. Cabsorbs all the light falling on it
    4. Dabsorbs other colours and reflects red
    Show answer and solution

    Answer: D. absorbs other colours and reflects red

    What the question is asking: Why does a red object look red in red light?

    Key idea: A red dye reflects red light and absorbs the other colours. Red light is exactly what it reflects, so it still looks red.

  8. Question 8 · UTME 2024 · Equilibrium of Forces

    A body is pulled along a horizontal surface by a rope inclined at 30° to the vertical. If the effective (horizontal) force pulling the body is 15 N, calculate the tension in the rope.

    1. A30 N
    2. B60 N
    3. C22.5 N
    4. D75 N
    Show answer and solution

    Answer: A. 30 N

    What the question is asking: The horizontal component of the tension is 15 N.

    Step 1 – At 30° to the vertical, the horizontal component is T sin 30°

    Step 2 – T × 0.5 = 15 → T = 30 N

  9. Question 9 · UTME 2024 · Conduction of Electricity Through Liquids and Gases

    In electrolysis, when the same quantity of electricity is passed through different electrolytes, the masses of the substances deposited are proportional to their

    1. Amolecular weights
    2. Bchemical equivalents
    3. Catomic numbers
    4. Dchemical equivalents per valency
    Show answer and solution

    Answer: B. chemical equivalents

    What the question is asking: State Faraday's second law.

    Key idea: For the same charge, the masses liberated are proportional to the chemical equivalents (relative atomic mass ÷ valency) of the substances.

  10. Question 10 · UTME 2024 · Measurements and Units

    A solid cube of aluminium is 1.5 cm on each edge. The density of aluminium is 2700 kg m⁻³. Find the mass of the cube.

    1. A7.5 g
    2. B9.1 g
    3. C12.0 g
    4. D15.0 g
    Show answer and solution

    Answer: B. 9.1 g

    What the question is asking: m = ρV

    Step 1 – V = 1.5³ = 3.375 cm³; density = 2.7 g cm⁻³

    Step 2 – m = 2.7 × 3.375 ≈ 9.1 g
