 A Point B Length C Distance D None of the above
Question 2 Explanation:
The distance between one end and the other desired end is called as length. It may be the distance between the edges of a book or a table or the corners of a football ground or even from your home to school.
 Question 3
The standard unit of length is
 A mm B cm C m D dm
Question 3 Explanation:
The standard unit of length is 'Metre'. It is represented by letter ‘m’. Very small lengths can be measured in mm and cm. Still larger measures, say height of a building, a banner or a lamp post are all measured in metre.

 Question 9
______ is a displacement or difference in the apparent position of an object viewed along two different lines of sight.
 A Syntax B Giopex C Parallax D Both a and c
Question 9 Explanation:
Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight.
 Question 10
For avoiding Parallax error eye must be exactly in front of_____ above the point where the measurement has to be taken.
 A Vertical B Horizontal C Anglicized D None of the above
Question 10 Explanation:
Correct position of the eye is also important for taking measurement. Your eye must be exactly in front of vertically above the point where the measurement has to be taken.
 Question 11
Using Length which of the following can be found
 A Area B Volume C Width D Both a and b
Question 11 Explanation:
Length is a fundamental quantity. That means, it connot be expressed in any other quantities. Using length, we can find out other measurements like Area and Volume. Area is obtained by using two lengths. So, Area = Length × Breadth.
 Question 12
Volume is a
 A Basic B Derived C Both a and b D None of the above
Question 12 Explanation:
Volume is also a derived quantity and it can be measured from measuring lengths.
 Question 13
Which of the following is not required to calculate the volume ?
 A Length B Breadth C Height D None of the above
Question 13 Explanation:
To know the volume of a box we need to know the length (l), breadth (b) and height (h). With a measuring scale measure the three parameters in cm. The volume of the box = l × b × h. Unit of volume would be obviously cm × cm × cm = cubic cm or cm.
 Question 14
Shape of liquid is
 A Oval B Rectangular C Shape of container D None of the above
Question 14 Explanation:
Measuring the volume of a liquid is quite easy. Liquids take the shape of the container in which they are kept. A liquid whose volume is to be found can simply be poured into a graduated container.
 Question 15
Which of the cannot be used to measure the volume of the liquids?
Question 15 Explanation:
Graduated cylinders, beakers, pipettes and burettes are available for measuring exact volumes. The volume of liquid is usually measured in litres.
 Question 16
Which of the following method can be used to measure the volume of irregular objects?
 A Stoning method B Water spilt method C Water displacement method D None of the above
Question 16 Explanation:
As the stone is immersed, we can observe that water level increases. Why? The stone displaces the water to occupy the space inside the measuring cylinder. How much water would be displaced? It would be equal to the space taken up by stone. So the amount of water displaced will be the volume of the stone. This method is called as water displacement method.
 Question 17
Convert the following 1ml=
 A 10 cm3 B 25 cm2 C 1cm3 D None of the above
Question 17 Explanation:
1ml = 1 cubic cm
 Question 18
What happens when you compress a gas
 A It will not compress B Occupies lesser space C Both a and b D None of the above
Question 18 Explanation:
Gases expand to fill the container into which they are placed. When you compress, a gas you can make the same gas to occupy lesser space. (as in LPG gas cylinder). Therefore it is not easy to talk about the volume of gas in the same way as a volume of a stone or a liquid.
 Question 19
Convert the following 1mm3=
 A 1 kilolitre B 1 millilitre C 1 microlitre D None of the above
 Question 20
Weight=
 A Mass x 9.81 B Mass x gravity C Both a and b D None of the above
Question 20 Explanation:
Mass is the measure of the amount of matter in an object. Weight is the gravitational pull experienced by the mass.
 Question 21
What will happen when you are in moon?
 A Mass gets reduced B Weight gets reduced C Both will get reduced D None of the above
Question 21 Explanation:
The weight is directly proportional to the mass on earths surface. On moon where the gravitational force is lesser than earth, the weight will reduce but the mass will remain same.
 Question 22
The moon’s gravitational pull is _______ of the earth’s pull.
 A 1/5th B 1/6th C 2/5th D 3/6th
Question 22 Explanation:
The moon’s gravitational pull is one sixth of the earth’s pull. Thus objects weigh six times lighter on the Moon than on the Earth.
 Question 23
Convert the following 1000 kg =
 A 10 tonnes B 1 tonne C 2 tonnes D None of the above
Question 23 Explanation:
Bigger weights are measured in tonne or Metric Tonne. 1000 milligram = 1 gram 1000 gram - 1 kilogram 1000 kilogram - 1 tonne.
 Question 24
We use beam balance to measure
 A Weight B Mass C Gravity D None of the above
Question 24 Explanation:
We use beam balances to measure mass. A beam balance works by comparing the mass of an object to that of known mass (called a standard mass).
 Question 25
What can be used to calculate rough time?
 A Food B Plants C Pulses D None of the above
Question 25 Explanation:
You can also use your pulse to measure ‘rough’ time. Count the number of pulses. That can tell you the time elapsed. In your normal speed of speaking, say “one little second”; “two little seconds” to count the passage of time.
 Question 26
Earlier days people used which of the following to measure rough time?
 A Sundial B Sand clock C Dogs D Both a and b
Question 26 Explanation:
In earlier days people used sand clock and sundial to measure the passage of time during the day. The shadow cast by a stick can be used to estimate time. One can also use a vessel with a small hole for computing time. Take a vessel or bottle with a small hole in it and fill it with water. The time taken for water to drain can also be used as a measuring device.
 Question 27
____ is a device used for indicating distance travelled by an automobile.
 A Speedometer B Odometer C Dualometer D None of the above
Question 27 Explanation:
An odometer is a device used for indicating distance travelled by an automobile.
 Question 28
The metric system or standard set of units was created by the ______ in 1790.
 A British B French C Danish D Dutch
Question 28 Explanation:
The metric system or standard set of units was created by the French in 1790.
 Question 29
