Answer: Option B. -> 0.1
:
B
Centimetre and millimetre are the units of length, relatedas
$1cm=10mm$
Therefore, $1mm=0.1cm$

Answer: Option C. -> G1- Falling Stone, G2- Sleeping Camel
:
C
Group 1: Falling Stone is an odd one as it is moving and the other examples are at rest.
Group 2: Sleeping Camelis odd one the Camelis at rest and the other examples are in motion.

Answer: Option B. -> (I)-c (II)-d (III)-b (IV)-a
:
B
SI unit of mass and length are kilogramand meter respectively. The pendulum of the clock repeats its motion at a fixed interval of time. This type of motion is known as periodic motion. The point on the blade of the fan undergoes circular motion.

Answer: Option D. -> Cubic metre
:
D
Metre, kilogram and kelvin are fundamental units. Metreis the fundamental unit of length, kilogram is the fundamental unit of mass and kelvin is the fundamental unit of temperature.
Cubic metreis a unit of volumeand is obtainedfrom the unit of length ($m$).

Answer: Option B. -> Airways
:
B
Airways takes minimum time to travel from one place to another. Aeroplanes can travel at very high speeds and consume less time for transportation.

Answer: Option A. -> 5.924 km
:
A
We know $1000m=1km$
$5924m=\frac{5924}{1000}km$
$5924m=5.924km$

Answer: Option D. -> Thread
:
D
Foot isnot a standard instrumentof measurement. The length of the foot may vary from person to person. So itcan't be used to measure the length of a curved line.
A thread is flexible. It can be bent easily to cover the curved line. It can then be straightened on a scale to measure the length.
Measuring cylinder is used to measure volume of liquids.
Thermometer is used to measure and indicatetemperature of any object.

Answer: Option C. -> Periodic motion.
:
C
A motion that repeats itself afterequal interval of time is called as periodic motion. For example,themotion of a pendulum and the motion of the Earth aroundthe Suncan be considered as aperiodic motionsince it repeats itself after an equal interval of time.

Answer: Option A. -> True
:
A
When a particle moves along the circumference of a circle it is said to be in a circular motion. The tip of the second's hand is doing circular motion as it is moving around a circular path with respect to the centre of the clock.

:
Each Point:1 Mark
1) Acar moving in a straight line is an example of linear motion.
2) The motion of the blades of a fan is an example of circular motion.
3) The rotation of the earth on its axis is an example of rotational motion.
