Express each of the following as indicated:
a) 2 dm expressed in millimeters
b) 2 h 10m expressed in seconds
c) 16 g expressed in micrograms
e) 0.675 mg expressed in grams
f) 462 um expressed in centimeters
g) 35/h expressed in meter per second

1 decimeter is equal to 100 millimeters. In this case, 2 decimeters is equal to 200 millimeters. 1 hour is equal to 3600 seconds while 1 minute is equal to 60 seconds. In this case, 2 h 10 minutes is equal to 7800 seconds. 1 gram is equal to 1000 micrograms. Thus, 16 grams is equal to 16000 mg and 0.675 mg is equal to 0.000675 grams. 1 centimeter is equal to 10000 micrometers. Hence 462 micrometers is equal to 0.0462 centimetes. 35 meter per hour is equal to 0.009722 m/s

The answer is b.the gaseous state is electrically positive, while the plasma state is electrically negative.
