,QUESTION 1This question consists of 20 short questions over a wide range of
measurements.
1.1. Name two different instruments that can be used to measure
time.
Two different instruments that can be used to measure time are a
clock and a stopwatch.
1.2 What is a cubit, and what does it measure?
A cubit is an ancient unit of measurement used by various
civilizations, including the ancient Egyptians, Greeks, and Romans. It
is typically defined as the distance from the elbow to the tip of the
middle finger of the person's hand, or roughly 18 inches (45.7
centimetres). The cubit was used to measure length, height, and
distance, and was commonly used in construction and architecture.
1.3What is the temperature of boiling water at sea level? Is the
boiling point at Durban and Johannesburg the same? Explain your
answer.
The temperature of boiling water at sea level is 100°C (212°F).
No, the boiling point at Durban and Johannesburg is not the same.
This is because the boiling point of water is affected by atmospheric
pressure and altitude. Durban is at sea level, so the atmospheric
pressure is higher than in Johannesburg, which is at a higher altitude.
This means that water will boil at a slightly higher temperature in
Durban than in Johannesburg, where the boiling point will be slightly
lower due to the lower atmospheric pressure.
1.4 What do you think of when you see the names Celsius and
Fahrenheit?
Celsius and Fahrenheit. They are both temperature scales used to
measure the degree of heat or coldness of an object or atmosphere.
, Celsius is often used in most countries around the world, whereas
Fahrenheit remains the standard in the United States.
1.5 What does SI stand for in measurement?
SI stands for "Système International d'Unités", which is the
international system of units used for measurement.
1.6 What did the Babylonians use to measure time?
The Babylonians used a number system based on 60, which they
applied to measure time. They divided the day into 24 hours, each
consisting of 60 minutes, and each minute consisting of 60 seconds.
This system of measuring time based on 60 is known as the
sexagesimal system and it is thought to have originated in Babylonia
around 2000 BCE.
1.7 How many square metres are there in a square kilometre?
There are 1,000,000 square metres in a square kilometre.
1.8 One inch = … cm. Give your answer correct to two decimals.
One inch = 2.54 cm.
1.9 What is the TARE of a truck?
The TARE of a truck refers to the weight of the empty vehicle,
including the fuel tank, but excluding any load or passengers. It is
used to calculate the maximum weight a truck can carry, which is
known as the Gross Vehicle Weight Rating (GVWR).
1.10 Why is our calendar called the Gregorian calendar?
Our calendar is called the Gregorian calendar in honour of Pope
Gregory XIII, who introduced it in 1582. The calendar was created to
replace the Julian calendar which had become out-dated and
inaccurate. The Gregorian calendar is used in most countries today.
