The eye changes the focal length of its lens to focus and changes the size of its pupil to control the light.

Diffusion is the spontaneous mixing of the particles of two substances, caused by the constant motion of those particles. Particles of matter are always moving and have spaces between them.

Vinoba Bhave asked every landowner to treat him as a son and give him a son's share, one-sixth of the land, for the landless.

Gravity is a conservative force, so the work it does never depends on the path. The work done by gravity on a body of mass m is mgh, where h is the vertical height between the start and the end.

On the magnetic equator the angle of dip is zero, so the Earth's magnetic field there is entirely horizontal. The Earth behaves like a huge bar magnet.

In a uniform field the two poles of the magnet feel equal and opposite forces, which cancel each other.

A caterpillar feeds directly on green leaves, so it is a herbivore, which is what a primary consumer is. In a food chain energy flows from producers to consumers.

Momentum is a vector, and on bouncing the ball's direction of motion reverses at once, from downward to upward. Just before impact the ball moves down with velocity v, so its momentum is mv downward.

The Fifth Plan (1974–79) made removal of poverty, or Garibi Hatao, and self-reliance its main aims. Garibi Hatao was the slogan with which Indira Gandhi's Congress won the 1971 Lok Sabha election.

Friction acts only where two surfaces touch, while a magnet can push or pull an object across a gap. Forces are grouped by whether the bodies must touch.

The 35th Amendment of 1974 made Sikkim an "associate State" of the Indian Union. Sikkim had been an Indian protectorate under the Chogyal.

Each piece has a resistance of 10 ohm, and five equal 10-ohm resistors in parallel give 10 ÷ 5 = 2 ohm.

Land left uncultivated for more than one year but less than five years falls in this class of India's land-use records.

Slate is a metamorphic rock, formed when shale is changed by heat and pressure. Igneous rocks form when molten magma or lava cools and hardens.

Steel is an alloy of iron with a small amount of carbon, and carbon is a non-metal. Ordinary steel carries roughly 0.05 to 2 per cent carbon.

This law let the government imprison people suspected of political activity without trial for up to two years. Officially the Anarchical and Revolutionary Crimes Act, it was passed in March 1919 on the advice of the Sedition Committee headed by Justice S.A.T.

One kelvin and one degree Celsius are the same size, so a rise of 30 K is also a rise of 30°C. The Kelvin and Celsius scales differ only in their starting point: T(K) = t(°C) + 273 (more exactly 273.15).

Work done by gravity depends only on the difference in potential between the two points, and here that difference is zero.

Only the gravitational field of a spherical body and the electrostatic field of a point charge fall off as 1/r².

High pressure pushes the gas molecules close together and low temperature slows them down, so the attractive forces can hold them as a liquid.
