7.5.1. Single Independent Variable

Try these first

1. 1.

   What is hydrostatics?

   Hint

   Focus on fluids that aren't moving.

2. 2.

   What is Pascal's Law?

   Hint

   Think about how pressure operates in a closed system.

3. 3.

   What does hydrostatics study?

   • Fluids in motion
   • Fluids at rest
   • Pressure Only

   Hint

   Think about which aspect of fluid mechanics this focuses on.

4. 4.

   Pascal's law states that pressure is transmitted equally in what?

   • True
   • False

   Hint

   Consider the applications of hydraulic systems.

5. 5.

   Calculate the pressure at a depth of 30 meters in a freshwater lake. Assume the density of water is 1000 kg/m³.

   Hint

   Consider the formula and ensure you multiply the density, gravity, and height correctly.

6. 6.

   A hydraulic lift uses Pascal's Law to amplify a force. If an input area of 0.1 m² is subjected to a force of 200 N, what is the output force if the output area is 1 m²?

   Hint

   Set up the ratios of forces per area correctly for your calculations.
