Question 1
1 / -0

For measuring length of the curve line, one should have:

A
A thread to measure the length of the curve line

B
One scale to measure the length of the thread

C
One steel rod to measure the length of the curve line

D
Both A and B

Solution

The length of a curve line can be measured with a thread. And the length of thread used can further be measured from a scale. In this way, we can measure the length of the curved line in two steps. One steel rod cannot be used to measure the length of the curved line.
Question 2
1 / -0

Fill in the blanks:

Each centimetre of a standard scale is divided into _____ parts.

A
$$100$$

B
$$10$$

C
$$1$$

D
$$1000$$

Solution

Length is measured by using a metre scale. A metre scale is divided into $$100$$ parts, called centimetres. Each centimetre is further divided into $$10$$ parts known as millimetres.
$$1$$ millimetre = $$0.1$$ centimetre
Question 3
1 / -0

Find the odd one out on the basis of motion with respect to earth.

A
Moon

B
Chair

C
Tree

D
Table

Solution

Moon
When the position of a body does not change with respect to its surroundings and time the body is said to be at rest.
But the moon is in motion with respect to earth while other objects like books, tables, and trees are in rest with respect to earth.
Question 4
1 / -0

Measuring height of your classmate will be more suitable by using which of the following?

A
Hand span

B
Metre scale

C
Metre tape

D
All of the above

Solution

Metre scale is the best suitable measuring instrument for measuring the height of classmate. We can often use Metre tape also, but in some cases, it can't give accurate measurements because it can bend or roundup while measuring.
Handspan measurement is an approximate measurement technic. Most of the time this technic does not give an accurate value.
Question 5
1 / -0

The following are the features of water transport :

A
Water transport plays an important role in international trade

B
It possesses high load carrying capacity

C
It is a relatively economical mode of transport for bulky and heavy goods.

D
All of the above

Solution

Water transport plays a significant role in international trade as it possesses a high load-carrying capacity. Also, water transport is a relatively economical mode of transport for bulky and heavy goods.
Question 6
1 / -0

Which of the following can be used to measure the length of a steel rod?

A
Metre Scale

B
Thread

C
Wooden scale

D
All of them

Solution

Length of steel rod can be measured either by metre scale, thread or wooden scale.
Question 7
1 / -0

Which of the following is the smallest unit?

A
millimetre

B
angstrom

C
fermi

D
metre

Solution

1 metre is the SI unit of length

1 millimetre (mm) is equivalent to $${{10}^{-3}}m$$

1 Angstrom is equivalent to $${{10}^{-10}}m$$

1 Fermi is equivalent to $${{10}^{-15}}m$$

This means fermi is the smallest unit

$$\textbf{Answer}$$

$$\textbf{Hence, the correct option is (c) fermi}$$
Question 8
1 / -0

The process of change in position of an object over time is called

A
rest

B
stationary

C
motion

D
none of the above

Solution

A body is said to be in motion if it changes its position over time.
Question 9
1 / -0

What is the type of motion of an object that moves in a straight line?

A
Rectilinear motion

B
Periodic motion

C
Circular motion

D
None of the above

Solution

Rectilinear motion is an another name for straight line motion.
Ex. A train moving on a track.
Question 10
1 / -0

The length of a rod is measured as $$31.52\ cm$$. Graduations on the scale are up to :

A
$$1\ mm$$

B
$$0.01 \ mm$$

C
$$0.1\ mm$$

D
$$0.02\ cm$$

Solution

Reading is upto $$2$$ decimal places for $$cm$$.
Hence graduation level will be upto $$2$$ places of decimal of cm and 1 place of decimal for $$mm$$.
