2. Wood is not a fluid. Fluids are substances that can flow and take the shape of their container, such as air, liquid, and gas. Wood is a solid material and does not have the ability to flow.3. Pressure is defined as the force exerted per unit area. It can be calculated using the formula: Pressure = Force / Area. This formula allows us to determine the pressure exerted by a force acting on a specific area.4. Archimedes' principle states that the buoyant force acting on an object submerged in a fluid is equal to the weight of the fluid displaced by the object. This principle helps us understand how objects float or sink in a fluid medium.5. The buoyant force of water on a piece of wood that floats is equal to the weight of the water displaced by the wood. Since the wood floats, the buoyant force must be equal to the weight of the wood.6. Pascal's principle states that pressure applied to a confined fluid is transmitted undiminished throughout the fluid. This means that any change in pressure applied to the fluid will be transmitted equally to all parts of the fluid.7. Bernoulli's Principle states that as the velocity of a fluid increases, the pressure within the fluid decreases, and vice versa. This principle explains the behavior of fluids in motion and is used to understand phenomena such as the lift generated by an airplane wing or the flow of air in a pipe.1. A fluid is a substance that can flow and take the shape of its container. Fluids can be in the form of liquids or gases. They have the ability to deform continuously under an applied force and can flow freely.
