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

(a) The length of a marathon race(26 miles 385 yards)
(b) The mass of an automobile
(c) The volume of a swimming pool
(d) The speed of an airplane
(e) The density of gold
(f) The area of a football field
(g) The maximum temperature at the South Pole on April 1,1913

Final answer:

The appropriate SI units for various measurements are the meter (m) for length, the kilogram (kg) for mass, the cubic meter (m³) for volume, meters per second (m/s) for speed, kilograms per cubic meter (kg/m³) for density, square meter (m²) for area, and kelvin (K) for temperature.

Step-by-step explanation:

(a) The appropriate SI base unit for length is the meter (m). Therefore, the length of a marathon race can be expressed as 42,195 meters.
(b) The appropriate SI base unit for mass is the kilogram (kg). Therefore, the mass of an automobile can be expressed in kilograms.
(c) The appropriate SI base unit for volume is the cubic meter (m³). Therefore, the volume of a swimming pool can be expressed in cubic meters.
(d) The appropriate SI derived unit for speed is meters per second (m/s). Therefore, the speed of an airplane can be expressed in meters per second.
(e) The appropriate SI derived unit for density is kilograms per cubic meter (kg/m³). Therefore, the density of gold can be expressed in kilograms per cubic meter.
(f) The appropriate SI derived unit for area is square meter (m²). Therefore, the area of a football field can be expressed in square meters.
(g) The appropriate SI base unit for temperature is the kelvin (K). Therefore, the maximum temperature at the South Pole on April 1, 1913 can be expressed in kelvin.
