Read each question carefully and perform the necessary unit conversions. Show all your work for full credit. Pay attention to significant figures.
1. Convert a speed of 95 km/h to meters per second (m/s).
2. The acceleration due to gravity is approximately 9.8 m/s². In feet per second squared (ft/s²), this is approximately ft/s².
3. A car travels a distance of 1500 meters. This is equivalent to kilometers.
4. Which of the following is the correct conversion factor to change cubic centimeters (cm³) to liters (L)?
1 cm³ = 1000 L
1 L = 100 cm³
1 L = 1000 cm³
1 cm³ = 1 L
5. Dimensional analysis is a technique used to check the consistency of equations and to convert units.
True
False
6. A fluid flows through a pipe at a rate of 25 gallons per minute (gal/min). Convert this flow rate to cubic meters per second (m³/s). (1 gallon = 3.785 L, 1 m³ = 1000 L)
