Question

Indicate the SI base units or derived units that are appropriate for the following measurements:

1. The mass of the moon
2. The distance from Dallas to Oklahoma City
3. The speed of sound
4. The density of air
5. The temperature at which alcohol boils
6. The area of the state of Delaware
7. The volume of a flu shot or a measles vaccination

Short answer

a) The mass of the moon, theappropriateunit is kilograms (Kg).

b) The distance from Dallas to Oklahoma City is measured in meters (m)

c) The speed of sound is measured in (m/s).

d) The density of air is expressed in Kg/m^3.

e) The temperature at which alcohol boils is measured inK( Kelvin).

f) The area of the state of Delaware is measured in m².

g) The volume of a flu shot or a measles vaccination is measured in m³.

Step-by-step solution

Determine the definition of base units and derived units.

A base unit is defined arbitrarily and not by combinations of other units. In contrast, A derived unit is a SI unit of measurement composed of a combination of the seven base units (Kg, m, s, A, K, mol, cd).

Determine the appropriate SI unit or derived unit

The appropriate SI base unit or derived units are as follows:

Mass:Kg

Distance:m,

Speed:m/s

Density:Kg/m³

Temperature:K

Area:m².

Volume:m³.

Therefore, the SI base unit for the mass of the moon is kilograms (Kg).

The SI base unit for the distance from Dallas to Oklahoma City is measured in meters (m).

The derived SI unit for the speed of sound is (m/s).

The derived SI unit for the density of air is Kg/m^3.

The derived SI unit for the temperature at which alcohol boils isK( Kelvin).

The derived SI unit for the area of the state of Delaware is m².

The derived SI unit for the volume of a flu shot or a measles vaccination is measured in m^3.
