Question 1
1 / -0

Which of the following is not the mode of transportation?

A
Railway transportation

B
Air transportation

C
Road transportation

D
None of the above

Solution

Railway, air, and road all are modes of transportation which are used to carry any kind of luggage, passengers, etc from one place to another.
Question 2
1 / -0

Which of the following is a type of motion?

A
Circular

B
Rectilinear

C
Periodic

D
All of the above

Solution

'A body is said to be in motion, if it changes its position with respect to its surrounding.'
Example;-Circular motion;"The motion of an object in a circular path is known as circular motion"
Linear motion-"(also called rectilinear motion) is one dimensional motion along straight line"
Periodic motion-Motion repeated in equal intervals of time
Question 3
1 / -0

If an object moves along a straight path it is said to be _______ or _______ motion. Fill in the blank.

A
Linear

B
one dimensional

C
two dimensional

D
both A and B

Solution

Linear motion (also called rectilinear motion) is one dimensional motion along straight line. It is called one-dimensional motion, because we can represent it using only one dimension/variable in a coordinate system. For example, we don't need both x and y variables to describe a linear motion. We can either use x or y.
Question 4
1 / -0

Which is the longest?

A
a kilometer

B
a centimeter

C
a decameter

D
a terameter

Solution
Question 5
1 / -0

Which of the following statement is correct?

A
Motion of soldiers on march past is a periodic motion

B
Motion of a train along a curved track on hills is the example of curvilinear motion.

C
Every periodic motion is also a oscillatory motion

D
Hockey player running after a ball is a combined motion

Solution

Motion of soldiers on march past in rectilinear motion Every oscillatory motion is also a periodic motion; Hockey player running after a ball is a random motion.

Hence only option $$b$$ is correct - Motion of a train along a curved track on hills is the example of curvilinear motion.
Question 6
1 / -0

While measuring the length of a wooden box, the reading at one end is 1.5 cm and the other end is 4.7 cm. What is the length of the wooden box?

A
4.7 cm

B
1.5 cm

C
3.2 cm

D
6.2 cm

Solution

The length of the wooden box = Difference between the reading at both the ends = 4.7 - 1.5 = 3.2 cm
Question 7
1 / -0

Which of the following is not necessary while measuring length ?

A
Placing the scale in contact with the object along its length.

B
Using full mark of the scale which is not broken.

C
Placing the eye exactly in front of the point where the measurement is to be taken

D
Using clean hands to make measuements

Solution

While measuring the length of the object, some precautions must be taken for accurate measurement. Scale should be placed in contact with the object along its length and broken scale should not be used. We must place the eye exactly in front of the point where the measurement is to be taken.
But the cleansing of hands has nothing to do with the measurement of length. THus option D is correct.
Question 8
1 / -0

Something that is used to transport people or things from one place to another is called _____________.

A
instrument

B
vehicle

C
machine

D
none of the above

Solution

A vehicle is a machine that transports people or cargo. Vehicles include wagons, bicycles, motor vehicles, railed vehicles, watercraft, amphibious vehicles, aircraft and spacecrafts.
The correct answer is B.
Question 9
1 / -0

How transport was carried out during medieval period ?

A
By roads

B
By airways

C
By vehicles

D
None of the above

Solution

Transports was carried out by roads, through ghats and across bridges on rivers. Cloth, foodgrains, groceries were transported by loading them on the backs of bullocks. Small boats were used in rivers. Messengers and camel riders carried letters to and fro.
Question 10
1 / -0

If someone is carrying a bulk amount of goods, then he should be taking which of the following mode of transportation?

A
Road transportation

B
Railway transportation

C
Air transportation

D
Water transportation

Solution

Rail transportation is the cheapest mode of transportation and it can be used to carry bulk amount of goods from one place to another.
