The coefficient of linear expansion of a metal is 0.001 per degree Celsius. If a rod of iron with length 1 meter at 20°C is heated to 100°C, what will be the increase in its length? (Take β = 0.001)
सही उत्तर: ख) 0.3 m
The change in length (ΔL) is given by ΔL = αL₀ΔT, where α is the coefficient of linear expansion, L₀ is the original length, and ΔT is the change in temperature. Substituting the values: ΔL = 0.001 * 1 m * (100°C - 20°C) = 0.3 m.

The process of ‘sink’ action in plant physiology refers to:
सही उत्तर: ख) The area where carbohydrates and other nutrients accumulate, attracting the flow of resources from elsewhere in the plant.
A ‘sink’ represents an area with high demand for sugars – typically fruits and developing seeds – that attracts the flow of assimilates (sugars) from photosynthetic sources elsewhere in the plant via phloem transport. Options 2, 3, and 4 describe other physiological processes.

The phenomenon of ‘etiolation’ in plants refers to rapid stem elongation due to a lack of light. Which hormone primarily mediates this response?
सही उत्तर: ख) Gibberellins
Etiolation is characterized by excessive stem growth and pale leaves caused by a surge of gibberellins in the absence of sufficient light. The other hormones are involved in different plant processes like cell elongation, shoot initiation, and fruit ripening.

If A = 1, B = 2, C = 3, and so on up to Z = 26, what is the value of 'ZXC'?
सही उत्तर: ग) 94
The code for a letter is simply its position in the alphabet. ‘Z’ is 26 and ‘X’ is 24 and ‘C’ is 3. Therefore, ZXC = 26 + 24 + 3 = 53.

A clock shows 9:00 AM. What will be the angle between the hour and minute hands?
सही उत्तर: क) 45 degrees
At 9:00 AM, the hour hand is at 9 and the minute hand is at 12. The angle between them is a right angle (90 degrees). The minute hand moves 360 degrees in 60 minutes, so it moves 6 degrees per minute. The hour hand moves 360 degrees in 12 hours (720 minutes), so it moves 0.5 degrees per minute. At 9:00 AM the difference between the two hands is 9 * 0.5 = 4.5 degree - 0 = 4.5 degrees as the minute hand position is 6 times more than that of the hour hand.

Find the odd one out: 25, 49, 81, 121
सही उत्तर: घ) 121
The numbers 25, 49, and 81 are perfect squares of odd numbers (5, 7, and 9 respectively). 121 is a perfect square of an even number (11). Therefore, 121 is the outlier in this sequence.

A man walks 5 meters East, then 3 meters North, then 2 meters West and finally 4 meters South. What is the distance from his starting point?
सही उत्तर: क) 8 meters
The man's movements can be broken down into components: East 5m, North 3m, West 2m, and South 4m. The net displacement in the East-West direction is 5m - 2m = 3m. The net displacement in the North-South direction is 3m - 4m = -1m (which is equivalent to 1m South). Using the Pythagorean theorem: distance = √(3² + 1²) = √10 meters. The most tempting incorrect answer is 8, as it’s a simple addition of the individual movements without considering cancellations.

Which of the following compounds is a strong acid?
सही उत्तर: ग) C. Hydrochloric Acid (HCl)
The correct answer is C. HCl is a strong acid due to its complete dissociation in water and produces a high concentration of hydrogen ions. Acetic acid, formic acid, and citric acid are all weak acids and only partially dissociate in water.

What is the primary function of a reducing agent in a chemical reaction?
सही उत्तर: ग) C. To increase the pH of the solution.
The correct answer is B. A reducing agent donates electrons to another substance (the oxidizing agent), thereby causing oxidation in that substance and reduction in itself. Option A describes an oxidizing agent; option C relates to pH changes; and option D refers to a catalyst.

The reaction between sodium hydroxide (NaOH) and magnesium carbonate (MgCO₃) produces sodium carbonate (Na₂CO₃), water, and carbon dioxide. Which of the following represents the balanced chemical equation for this reaction?
सही उत्तर: ख) B. NaOH + MgCO₃ → NaHCO₃ + H₂O + CO₂
The correct answer is A. This equation correctly represents the stoichiometry of the reaction between sodium hydroxide and magnesium carbonate to produce the expected products. Options B incorrectly simplifies the equation; C overproduces sodium carbonate; and D has incorrect chemical formulas.
