(a) 1m-100cm
Answer: True
(b) 5000m 5 cm
Answer: false
(c) 2000 mm = 2 cm
Answer: false
(d) Movement of a clock hand is an example of linear motion
Answer: false
(e) Motion in a straight line is called as oscillatory motion.
Answer: false
Q.4. Darken the circle of correct answer.
(i) Which of the following is an example of periodic motion?
(A) A bus moving in the road
(B) A swing pendulum
(C) A falling ball
(D) A walking person
Answer:(b)
(ii) Which of the following is an example of circular motion?
(A) A swing in motion
(B) A moving train
(C) A ceiling fan’s blade in motion
(D) A moving cycle
Answer:(c)
5. Convert the followings:
(a) 250 mm to m
Answer: 250 mm = 250/ 1000 m = 0.25m
(b) 7.5 km to m
Answer: we know that. 1km = 1000m
∴ 7.5 km = 7.5 × 1000m
= 7500m
(c) 3m to cm
Answer:
3m = 3 x 100 cm
= 300 cm
(d) 1.25m to mm
Answer: we know that,
1m = 1000mm
.:. 1.25m = 1.25 × 1000mm
= 1250mm
Q.6. Distance between your home and school is 2000m, convert it into kilometer
Answer: We know that,
1 km = 1000 m
∴ The Distance between home and school = 2000m
= 2 × 1000m
= 2.x 1km
= 2km
