Choose the correct conclusion based on the given fact and statements. Fact: Climate change refers to long-term variations in temperature and precipitation patterns. Statement 1: This can lead to rising sea levels due to melting of ice. Statement 2: It makes the Earth move farther away from the Sun every year. Fact is incorrect but both the statements are correct. Fact and statement 1 are correct but statement 2 is incorrect. (iv) The fact and statement 2 are correct but statement 1 is wrong. Fact and statement 2 are correct but statement 1 is incorrect.

(iii) Fact and statement 1 are correct but statement 2 is incorrect.

Which of the following statements is correct? Value of acceleration due to gravity decreases when we go higher from the surface of the Earth. Value of acceleration due to gravity decreases when the height increases from the surface of the Earth. Value of acceleration due to gravity is less at the polar regions than the equatorial region of the Earth. Value of acceleration due to gravity is the most at the highest peak of the Earth.

(ii) The value of gravitational acceleration decreases as altitude above the Earth's surface increases. [Important: option (i) also states exactly the same thing in other words — 'going to a higher altitude it decreases' and 'as altitude increases it decreases' are the same statement. Both are true, so there are two correct options for this question and a student writing (i) is not wrong either.]

Study the given diagram and identify p and q. [First figure: a ray arriving from the denser medium strikes the surface and the refracted ray grazes along the surface itself (at 90^\circ to the normal); p is the angle between the incident ray and the normal. Second figure: the ray does not leave the surface and turns back into the denser medium (total internal reflection); q is the angle between the normal and the returning ray.] (i) p - angle of refraction and q - critical angle. (ii) p - critical angle and q - angle of reflection. (iii) p - angle of incidence, q - angle of refraction. (iv) p - critical angle and q - angle of refraction.

(ii) p- critical angle and q- reflected angle

Which of the following equation is correct for the chemical reaction while burning magnesium with nitrogen? (i) Mg + N —Δ→ MgN (ii) Mg + N₂ —Δ→ MgN₂ (iii) 3Mg + N₂ —Δ→ Mg₃N₂ (iv) 6Mg + N₂ —Δ→ 2Mg₃N₂

(iii) 3Mg + N₂ —Δ→ Mg₃N₂

Study the following statement and arguments about soap. Statement: Soap is environment friendly. Argument 1: Soap is biodegradable, hence does not pollute environment. Argument 2: Soap gives scum in hard water and makes clothes and utensil clean. Statement and argument 1 are wrong but argument 2 is correct. Statement and argument 2 are correct but argument 1 is wrong. Statement and argument 2 are wrong but argument 1 is correct. Statement and argument 1 are correct but argument 2 is wrong.

(iv) Both the statement and Reason 1 are correct, but Reason 2 is incorrect.

Why is the controlled variable kept unchanged in scientific experiment?

Because it can be established that the change observed in the dependent variable is caused by the independent variable. If the controlled variables also change, then it is impossible to distinguish which cause produced the difference seen in the results, and the experiment becomes unreliable.

Bat and whale have many dissimilarities, yet they are kept in the same class, why?

Because classification is not based on habitat or external appearance, but on fundamental bodily characteristics — and both have all the main features of the class Mammalia: \cdot Both are warm-blooded. \cdot Both breathe using lungs. \cdot Both give birth to live young and feed them with milk from mammary glands. \cdot Both have hair on their bodies at some stage and have four-chambered hearts. Therefore, although a bat flies in the air and a whale swims in water, both belong to the class Mammalia (Mammalia).

Free fall is the motion of an object falling downward without any force other than the gravitational force (for example air resistance) acting on it. In such a case the object's initial velocity is zero and it falls with uniform acceleration g — irrespective of mass, all objects fall at the same rate.

Draw a graph to show the relationship between alternating current and time.

In which group of modern periodic table does the element having electronic configuration 1\text{s}^{2}, 2\text{s}^{2}2p^{6}, 3\text{s}^{2} lie?

Group IIA (Group 2). Reason: Total electrons = 2 + 2 + 6 + 2 = 12, i.e., this is magnesium. Its outermost shell (n = 3) has 3\text{s}^{2} — i.e. 2 electrons. For main-group elements the group number is determined by the number of valence electrons, therefore it belongs to group IIA. (Period = 3, because three shells are filled.)

Why is magnetic separation used in metallurgy?

Because one of the ore and the impurities (gangue) mixed in it is magnetic and the other is non-magnetic, a magnet can easily separate them. Method: The crushed ore is placed on a moving belt. A magnetic roller located at the end of the belt attracts the magnetic portion and drops it nearby while the non-magnetic portion flies off and falls farther away — in this way two heaps are formed. Example: Magnetite (Fe₃O₄) is separated from sand and other non-magnetic impurities using this method.
