Q1 · Physics · Work, Energy and Power
A body of mass 1.2 kg, at rest on a smooth horizontal surface, is pushed by a horizontal force that rises uniformly from zero to 12 N over the first 2 m, stays at 12 N for the next 3 m, and then falls uniformly to zero over the last 2 m. What is the speed of the body after these 7 m?
- (A) 11.8 m s⁻¹
- (B) 7.07 m s⁻¹
- (C) 10 m s⁻¹
- (D) 7.75 m s⁻¹
Show answer and explanation
Answer: (C)
The work done is the area under the force–displacement graph: ½ × 2 × 12 + 3 × 12 + ½ × 2 × 12 = 12 + 36 + 12 = 60 J. By the work–energy theorem this equals the gain in kinetic energy, so ½ × 1.2 × v² = 60, v² = 100 and v = 10 m s⁻¹.
Q2 · Chemistry · Thermodynamics
The enthalpy of solution of anhydrous CuSO₄(s) in excess water is −66.5 kJ mol⁻¹, while that of CuSO₄·5H₂O(s) is +11.7 kJ mol⁻¹. What is the enthalpy change for CuSO₄(s) + 5H₂O(l) → CuSO₄·5H₂O(s)?
- (A) +78.2 kJ mol⁻¹
- (B) −54.8 kJ mol⁻¹
- (C) +54.8 kJ mol⁻¹
- (D) −78.2 kJ mol⁻¹
Show answer and explanation
Answer: (D)
Both solids give the same solution of CuSO₄(aq). Take the dissolution of anhydrous CuSO₄ (ΔH = −66.5) and reverse the dissolution of the pentahydrate (ΔH = −11.7). The solution cancels, leaving CuSO₄ + 5H₂O → CuSO₄·5H₂O. ΔH = −66.5 + (−11.7) = −78.2 kJ mol⁻¹.
Q3 · Botany · Photosynthesis in Higher Plants
In Hill's experiment, isolated chloroplasts are illuminated in a suspension containing an artificial electron acceptor (such as ferricyanide) but no CO₂. Which result best supports the conclusion that the light reaction can proceed independently of CO₂ fixation?
- (A) Oxygen is evolved in the light, showing that water splitting and electron transport occur without CO₂ being fixed.
- (B) Carbon dioxide is released in the light, showing that the light reaction produces CO₂ from the acceptor.
- (C) No oxygen is evolved unless CO₂ is added, showing that CO₂ is the electron donor for water splitting.
- (D) NADPH accumulates in the dark after illumination, showing that the artificial acceptor is reduced by the Calvin cycle.
Show answer and explanation
Answer: (A)
Principle: in the light reaction, PSII splits water and releases O₂, and electrons flow to an acceptor. Hill's experiment used isolated chloroplasts with ferricyanide as an artificial acceptor. O₂ was evolved in light even though no CO₂ was supplied. This shows that the light-dependent water splitting and electron transport are separate from the carbon fixation steps of the Calvin cycle. Students who pick the CO₂-related options are mixing up the light reaction with the dark reactions or with photorespiration.
Q4 · Zoology · Breathing and Exchange of Gases
Air moving from the trachea towards the alveoli passes through a sequence of conducting and respiratory airways. Which airway segment is the first in which gas exchange can take place?
- (A) Terminal bronchioles, because they are the last segment of the airway before the alveoli.
- (B) Respiratory bronchioles, because alveoli first open into their walls.
- (C) Alveolar ducts, because they are the first structures that are lined by alveolar epithelium.
- (D) Primary bronchi, because they are the first airways that carry air into the lungs.
Show answer and explanation
Answer: (B)
The respiratory system has a conducting zone, which carries air and has no alveoli, and a respiratory zone, which exchanges gases. The boundary is the respiratory bronchiole, where alveoli first appear in the walls. The sequence runs trachea, bronchi, bronchioles, terminal bronchioles (conducting), respiratory bronchioles (first exchange site), alveolar ducts, alveolar sacs. Students usually misplace the boundary by one generation, either too early at the terminal bronchioles or too late at the ducts.
Questions
About the free NEET mock.
Is the NEET mock test really free?
Yes. The free plan includes 2 full-length NEET mocks a month and 60 practice questions a day, with no card needed. Nikaalle is run by a non-profit trust.
Is it on the real NEET pattern?
Yes: 180 compulsory questions — 45 each in Physics, Chemistry, Botany and Zoology — 720 marks, 3 hours, +4 for a correct answer, −1 for a wrong one, 0 for a blank. It follows the current NMC syllabus, so nothing removed in 2024 is asked.
Do I get explanations and analysis?
Every question has an explanation of why the answer is right and why each wrong option is tempting. The result breaks down by subject, chapter, topic and time, and names what to revise next.
Is there an all-India rank?
Weekly contests are sat by everyone in the same window and ranked by score, then time. See the contests page for the next one.
Can I take it in Hindi?
Not yet. Hindi-medium mocks are being prepared and will be listed here when they are ready.
