Question 1
1 / -0

Metre scales have bevelled edge to :

A
increase the grip between scale and the measured surface

B
avoid errorrs due to parallax

C
look good

D
None of these

Solution

A bevelled edge or beveled edge is an edge of a structure that is not perpendicular to the faces of the piece. Metre scales have bevelled edges to avoid errors due to parallax.
Question 2
1 / -0

Name unit of length which is bigger than a metre?

A
centimetre

B
millimetre

C
kilometer

D
nanometre

Solution

1 Kilometre = 1000 m
Question 3
1 / -0

Which of the following shows a motion in a straight line?

A
Train on a straight bridge

B
Tree swaying

C
Child on a merry-go-round

D
None of these

Solution

Only train on a straight bridge shows a straight line motion, rest all are not straight line motion.
Question 4
1 / -0

Write the name of unit of length smaller than a metre?

A
Kilometre

B
decametre

C
hectometre

D
centimeter

Solution

1m = 100 cm
Question 5
1 / -0

The least value measured with metre-scale is (if the metre scale is divided into 1000) ....................... .

A
1 mm

B
1 m

C
1 cm

D
1 nm

Solution

Since, $$1 \ metre$$ is divided into $$1000$$ divisions.
Least count of metre scale $$L.C. = \dfrac{1 \ m}{1000} = 0.001 \ m = 1 \ mm$$
Question 6
1 / -0

The SI unit of mass is:

A
Newton

B
Kilogram

C
Kilometer

D
Gram

Solution

Mass is the measure of the amount of matter in a body. The SI unit of mass is Kilogram $$(kg)$$.

Which of the following represents circular motion:

A
Ball sliding down on an inclined plane

B
Motion of a simple pendulum

C
A freely falling body

D
A stone tied to a thread and whirled

E
None of these

Solution

An object moving in a circular path is said to be in a circular motion. A stone tied to a thread and whirled represents circular motion, A ball sliding down an inclined plane and a freely falling body represents a linear motion, while motion of a simple pendulum is periodic but not circular. Hence, option D is correct.
