Passage – 1 In India, the segregation of municipal waste at source is rare. Recycling is mostly with the informal sector. More than three-fourths of the municipal budget goes into collection and transportation, which leaves very little for processing/resource recovery and disposal. Where does waste-to-energy fit into all this? Ideally it fits in the chain …
Arithmetic Progression (AP) is a fundamental concept in mathematics, particularly in the field of algebra and sequences. It is a sequence of numbers in which each term after the first one is obtained by adding a constant value to the preceding term. This constant value is known as the “common difference” and is denoted by …

Rejuvenation refers to the process by which a landscape experiences renewed erosion and reshaping after a period of relative tectonic stability or reduced erosion. It occurs when external forces, such as tectonic movements, changes in climate, or alterations in base level, disrupt the equilibrium of a landscape and lead to increased erosion and landform development. …
Diastrophism refers to the collective processes that deform the Earth’s crust and create changes in its shape and size over geologic time. These processes involve movements of large-scale crustal blocks due to tectonic forces acting within the Earth’s lithosphere. Diastrophism plays a fundamental role in shaping the Earth’s surface and is responsible for the formation …
Karst topography is a unique type of geological formation that develops in regions with soluble rocks, such as limestone, gypsum, and dolomite. It is characterized by distinctive surface features, including sinkholes, caves, underground rivers, disappearing streams, and rugged terrains with irregular and jagged landforms. Karst landscapes are created primarily through the process of chemical weathering …
To convert a complex number from rectangular form (a + bi) to polar form (r ∠ θ), follow these steps: Identify the real part (a) and the imaginary part (b) of the complex number. Calculate the magnitude (r) of the complex number using the formula: r = √(a^2 + b^2). Determine the angle (θ) of …
