Numericals on Physical Quantities and Measurement
Ques-1: Convert the following quantities as indicated :
(i) 12 inch = …………… ft
Ans- (i) 12 inch = 1 ft
(ii) 1 ft = …………… cm
Ans- (ii) 1 ft = 30.48 cm
(iii) 20 cm = …………… m
Ans- (iii) 1 cm = 10-2 m
⇒ 20 cm = 20 x 1 cm = 20 x 10-2 m
⇒ 20 cm = 0.2 m
(iv) 4.2 m = …………… cm
Ans- (iv) 1 m = 100 cm
⇒ 4.2 m = 4.2 x 100 cm = 420 cm
(v) 0.2 km = …………… m
Ans- (v) 1 km = 1000 m
⇒ 0.2 km = 0.2 x 1000 m = 200 m
(vi) 0.2 cm = …………… mm
Ans- (vi) 1 cm = 10 mm
⇒ 0.2 cm = 0.2 x 10 mm = 2 mm
(vii) 1 yard = …………… m
Ans- (vii) 1 yard = 0.91 m
Que-2: Express in second
(i) 3 minute 15 second
Ans– (i) 1 minute = 60 second
then, 3 minute 15 second = 3 minutes + 15 seconds = 3 x 60 seconds + 15 seconds = (180 + 15) seconds = 195 seconds
(ii) 5 hour 2 minute 5 second
Ans- (ii) 1 hour = 3600 seconds
and 1 minute = 60 seconds
then, 5 hour 2 minute 5 second = 5 x 3600 seconds + 2 x 60 seconds + 5 seconds = (18000 + 120 + 5) seconds = 18125 seconds
Que-3: Convert the following quantities as indicated :
(i) 2500 kg = …………… metric tonne
Ans- (i) 1 kg = 10-3 metric tonne
⇒ 2500 kg = 2500 x 10-3 metric tonne
⇒ 2500 kg = 2500/1000 metric tonne = 2.5 metric tonne
(ii) 150 kg = …………… quintal
Ans- (ii) 1 kg = 10-2 quintal
⇒ 150 kg = 150 x 10-2 quintal
⇒ 150 kg = 150/100 quintal = 1.5 quintal
(iii) 10 lb = …………… kg
Ans- (iii) 1 lb = 0.45359 kg
⇒ 10 lb = 10 x 0.45359 kg = 4.5359 kg
(iv) 2500 g = …………… kg
Ans- (iv) 1 g = 10-3 kg
⇒ 2500 g = 2500 x 10-3 kg
⇒ 2500 g = 2500/1000 kg = 2.5 kg
(v) 0.01 kg = …………… g
Ans- (v) 1 kg = 1000 g
⇒ 0.01 kg = 0.01 x 1000 g = 10 g
(vi) 5 mg = …………… kg
Ans- (vi) 1 mg = 1 x 10-6 kg
5 mg = 5 x 10-6 kg
