physics

1)convert the following:

a)change 2.75 km to cm
b)change 455 cg to g
c)change 45 dm to m
d)change 3.5 hg to g
e)change 67 mm to m
f)change 0.005 kg to cg

2)convert 45.3 cm to its equivalent measurement in mm.

3)convert the lenght of 56.43 ft to its equivalent measurement in meters.

4)change the speed of 72.4 miles per hour to its equivalent in meter per second?

5)how many grams are in 17 lbs?

6)which is faster 55 mi/h or 40 km/h?

7)which is faster 80 mi/h or 40 m/s?

8)Imagine the water is leaking from a container,at a rate of 1.2 ml/h if this rate dose not change,how many liters of water will be lost in a week?

note: (1mi=1.609km)

1.
a)2.75 km =275000cm
b)455cg = 4.55g
c)45dm = 4.5m
e) 67mm = 0.067m
f) 0.005kg =50cg

2. 45.3cm = 453mm

3. 56.43 ft = 56.43/3 m

4.72.4 ml/h = 32.36m/s
5. 17lb = 7650 g
6. 55ml/h = 88.5km/h (faster) > 40 km/h
7. 80ml/h = 35.76 m/s (slower) < 40m/s
8.The amount of water will be lost in one week is 0.2016 Liter
