QUESTION 1
1.1 Two different instruments that can be used to measure time are a clock and a
stopwatch.
Chronometer and hourglass.
1.2 Cubit, unit of linear measure used by many ancient and medieval peoples. It may
have originated in Egypt about 3000 BC; it thereafter became ubiquitous in the
ancient world. The cubit, generally taken as equal to 18 inches (457 mm), was
based on the length of the arm from the elbow to the tip of the middle finger and
was considered the equivalent of 6 palms or 2 spans. In some ancient cultures it
was as long as 21 inches (531 mm).
1.3 To give you some idea of the effects of altitude, at sea level, the boiling point of
water is 212 degrees Fahrenheit, or 100 degrees Celsius. As you move up into
the higher altitudes, the boiling point of water becomes much lower. In
Johannesburg the boiling point of water drops to 201 F, or 94 C.
1.4 Celsius and Fahrenheit are two scales used to measure temperature. The
temperature in the centigrade scale will be expressed in degrees Celsius. The
temperature in the Fahrenheit scale will be expressed in degrees Fahrenheit. The
relation between Celsius and Fahrenheit is proportional.
1.5 Système Internationale
The International System of Metric Units
S.I. is an abbreviation of Système Internationale or International System: our
metric system of measurements. It is an internationally standardised system,
giving a common language between nations and between the different branches
of science and technology.
1.6 Sexagesimal, also known as base 60 or sexagenary, is a numeral system with
sixty as its base. It originated with the ancient Sumerians in the 3rd millennium BC,
was passed down to the ancient Babylonians, and is still used—in a modified form—
for measuring time, angles, and geographic coordinates.
1.7 1 square kilometer = 1,000,000 square meters
1.8 1 inch = to 2.54 cm.
1.9 Tare weight is defined as the total weight of tractor and trailer when the vehicle is
empty, meaning there is not any product in the trailer. Tare weight can also be called
unladen weight.

1.10 The Gregorian Calendar
The calendar was originally invented by Pope Gregory XIII, from whom it gets its
name. It was developed in 1582 and was based on a design by a man named Luigi
Lilio, also known as Aloysius Lilius.
1.11 The main difference between equinox and solstice is that equinox is the time
when the Sun crosses the plane of the Earth’s equator, while solstice is the time
when the Sun’s path is farthest north or south from Earth’s equator.
Both equinox and solstice occur twice a year. They signal the changing of seasons
on Earth. Equinoxes mark the beginning of fall and spring, while solstice occurs
during summer and winter. Moreover, equinox results in equal lengths of day and
night while result in changes in the length of the days and nights.
1.12 A leap year is a period of 366 days. What is a leap year? To be a leap year, the
year number must be divisible by four – except for end-of-century years, which must
be divisible by 400. This means that the year 2000 was a leap year, although 1900
was not. 2024, 2028, 2032 and 2036 are all leap years.
1.13 9.995 cm with two decimal places is 10.00 cm
1.14 hectare, unit of area in the metric system equal to 100 ares, or 10,000 square
metres, and the equivalent of 2.471 acres in the British Imperial System and the
United States Customary measure. The term is derived from the Latin area and from
hect, an irregular contraction of the Greek word for hundred.
1.15 A thermostat is a regulating device component which senses the temperature of
a physical system and performs actions so that the system's temperature is
maintained near a desired setpoint.
1.16 There are 86,400 seconds in 1 day.
1.17 1 Liter is equal to 1000 cubic centimeters
1.18 The average normal body temperature is generally accepted as 98.6°F (37°C).
Some studies have shown that the "normal" body temperature can have a wide
range, from 97°F (36.1°C) to 99°F (37.2°C). A temperature over 100.4°F (38°C) most
often means you have a fever caused by an infection or illness.
1.19 The measuring wheel – also known as a surveyor's wheel, clickwheel,
odometer, or trundle wheel – is a tool used to measure distances. Measuring wheels
have a counting mechanism that counts the number of rotations and uses the
circumference of the wheel to calculate the distance covered.
1.20 Feet and inches have a similar symbol. For feet, a single apostrophe is used (').
For inches, a double apostrophe is used (”).
