Floating of heavy objects is not a consequence of surface tension; it is due to buoyancy, while the other options are directly related to surface tension.

Prism dispersion involves refraction and not total internal reflection. The other options are phenomena that utilize total internal reflection.

Conduction is a mode of heat transfer and is not associated with wave phenomena.

The photoelectric effect is explained by quantum mechanics and particle nature of light, not by wave optics.

Floating of heavy objects is not related to surface tension; it is related to buoyancy. The other phenomena are directly influenced by surface tension.

Capillary action is primarily due to surface tension, as it allows liquids to rise in narrow tubes against gravity.

Refraction is the bending of light as it passes from one medium to another due to a change in its speed.

The blue color of the sky is primarily due to Rayleigh scattering, which scatters shorter wavelengths of light more than longer wavelengths.

The formation of a rainbow is primarily due to the refraction and dispersion of light in water droplets.

Existentialism focuses on individual experience and the subjective interpretation of existence and truth.

The phrase 'the main point' accurately captures the essence of 'the crux of the matter'.

Industrial expansion contradicts the theme of environmental conservation, while the others promote it.

Individual effort is paramount contradicts the theme of teamwork, which emphasizes collaboration.

He was unprepared contradicts the positive outcomes suggested by the other phrases.

The phrase 'a cycle of disadvantage' reflects the ongoing nature of systemic inequality discussed in the passage.

The phrase 'On the contrary,' signals a shift in the author's argument, introducing a contrasting viewpoint.

The phrase 'We must strive for equity' indicates a call to action, urging readers to take steps towards addressing inequalities.

Industrial expansion often leads to increased resource consumption and environmental degradation, making it the least related to sustainability.

The Chola dynasty is noted for its extensive development of irrigation canals which significantly enhanced agricultural productivity.

Pteridophytes, like ferns, exhibit an alternation of generations with both gametophyte and sporophyte stages.

All of the mentioned groups (Angiosperms, Gymnosperms, and Pteridophytes) exhibit alternation of generations in their life cycles.

The distance from the origin to a point (x, y) is given by √(x² + y²). The point (0, 1) has a distance of 1, which is the smallest.

The point (2, 3) is the midpoint of the segment joining (1, 2) and (3, 4), making it equidistant from both.

Substituting (0, -4) into the equation gives 4(0) - 5(-4) + 20 = 0, which is true.

Substituting x = 2 into the equation y = 2(2) + 1 gives y = 5, so the point (2, 5) lies on the line.

Substituting x = 1 into the equation gives y = 1^2 - 4 = -3, so the point (1, -3) lies on the parabola.

To check if a point lies on the parabola, substitute the x-coordinate into the equation. For (2, 4), 4^2 = 16 and 8*2 = 16, so it lies on the parabola.

Land Reforms were aimed at redistributing land to the landless and ensuring equitable access to resources, thus promoting inclusive growth.

The Doctrine of Lapse was a policy that allowed the British to annex any princely state if the ruler died without a male heir, which contributed to the discontent leading to the Rebellion of 1857.

The Integrated Rural Development Programme was launched in the 1970s to provide employment and promote self-reliance among the rural poor.
