It produces no goods at all; it provides services such as transport, storage, communication, trade, banking, insurance, education, health care and administration, which is why it is commonly called the service sector.

Mining takes a product straight out of nature without changing its form, exactly as farming, fishing and forestry do, and every activity of that kind is placed in the primary sector.

The meridian of 82 degrees 30 minutes east passes near this town, and its local time is kept as Indian Standard Time across the whole country.

Every meridian runs from the North Pole to the South Pole, so all meridians are semicircles of the same length and all of them converge at the two poles.

Indian Standard Time is the local time of 82 degrees 30 minutes east. Multiplying 82.5 degrees by four minutes gives 330 minutes, that is five hours and thirty minutes, and since India lies east of Greenwich its clock is ahead by that much.

The circumference of the earth along a meridian is close to 40,000 kilometres, and dividing that by 360 degrees gives roughly 111 kilometres for one degree of latitude.

There are 90 parallels in the northern hemisphere, 90 in the southern hemisphere and the equator itself, which belongs to neither, making 181 in all.

The line does not follow it exactly: it bends east and west to keep the eastern tip of Siberia, the Aleutian Islands and several Pacific island groups on one side, so that no country is left with two dates at the same moment.

This meridian passes near Mirzapur in Uttar Pradesh and runs roughly through the middle of the country, so it was adopted as the standard meridian of India.

Whether the hands are moved or not, the momentum of the ball must be brought down to zero.

Inertia is the tendency of a body to resist any change in its state of rest or of uniform motion, and the heavier the body the harder it is to start or to stop.

The slope of any graph is the change on the vertical axis divided by the change on the horizontal axis; here that is distance divided by time, which is speed by definition.

The third law says that to every action there is an equal and opposite reaction, and the crucial point is that the two forces act on two different bodies.

On a velocity-time graph the height of the curve is velocity and the base is time, so the area enclosed is velocity multiplied by time, which is displacement.
