Question

answer each of the following questions as directed.

1. the basic si unit for measuring length is the meter. using metric prefixes, give the appropriate unit for measuring the following quantities.

example: the distance between two cities kilometers
a. the distance between your eyes
b. the diameter of wire used to make a paper clip
c. the length of a football field
d. the thickness of a piece of paper

1. the basic si unit of mass is the kilogram. using metric prefixes, give the appropriate unit for measuring the following quantities.

example: the mass of a person kilograms
a. the mass of aspirin in an aspirin tablet
b. the mass of the empire state building
c. the mass of an apple
d. the mass of an automobile

1. a non - si unit frequently used to measure volume is the liter. using metric prefixes, give the appropriate unit for measuring the following quantities.

example: the volume of an eyedropper milliliters
a. the volume of water in a bathtub
b. the volume of a can of soda
c. the volume of a swimming pool
d. the volume of a microwave oven

1. indicate a quantity that could be measured in the following units.

example: gram the mass of a soup bowl
a. millisecond
b. megawatt
c. decigram
d. kilocalorie

Explanation:

Step1: Determine appropriate length - related units

a. The distance between eyes is small, so centimeters (cm) are appropriate.
b. The diameter of a paper - clip wire is very small, so millimeters (mm) are appropriate.
c. The length of a football field is a moderate length, so meters (m) are appropriate.
d. The thickness of a piece of paper is extremely small, so micrometers ($\mu m$) are appropriate.

Step2: Determine appropriate mass - related units

a. The mass of aspirin in a tablet is small, so milligrams (mg) are appropriate.
b. The mass of the Empire State Building is huge, so megagrams (Mg) are appropriate.
c. The mass of an apple is moderate, so grams (g) are appropriate.
d. The mass of an automobile is large, so kilograms (kg) are appropriate.

Step3: Determine appropriate volume - related units

a. The volume of water in a bathtub is large, so liters (L) or kiloliters (kL) can be used, but liters are more common, so liters (L).
b. The volume of a can of soda is small, so milliliters (mL) are appropriate.
c. The volume of a swimming pool is very large, so kiloliters (kL) are appropriate.
d. The volume of a microwave oven is moderate, so liters (L) are appropriate.

Step4: Determine quantities for given units

a. Millisecond is a unit of time, so it can measure the time interval of a short - duration event like the time it takes for a camera's shutter to open.
b. Megawatt is a unit of power, so it can measure the power output of a large electrical generator.
c. Decigram is a unit of mass, so it can measure the mass of a small object like a small piece of jewelry.
d. Kilocalorie is a unit of energy, so it can measure the energy content of a meal.

1. a. mg

b. Mg
c. g
d. kg

1. a. L

b. mL
c. kL
d. L

1. a. The time interval of a short - duration event

b. The power output of a large electrical generator
c. The mass of a small object like a small piece of jewelry
d. The energy content of a meal
