The correct Answer is:
To analyze the given statements, we can break down the reasoning step by step. ### Step-by-Step Solution: 1. **Understanding Statement 1**: - The first statement claims that "the instantaneous velocity is always tangential to the path." - This means that at any given point on the path of a moving object, the direction of the velocity vector (which indicates the direction of motion) is along the tangent to the path at that point. 2. **Understanding Statement 2**: - The second statement says, "the slope of the position-time graph represents the velocity." - In a position-time graph (x-t graph), the slope at any point gives the velocity of the object at that specific time. If the graph is curved, the slope at a particular point can be found by drawing a tangent to the curve at that point. 3. **Connecting the Statements**: - The instantaneous velocity being tangential to the path (Statement 1) implies that the direction of the velocity vector is along the tangent line to the path. - The slope of the position-time graph (Statement 2) represents the velocity. Therefore, if we take the slope at a point on the x-t graph, it gives us the instantaneous velocity, which is also tangential to the path at that point. 4. **Conclusion**: - Both statements are correct. Statement 1 is supported by Statement 2 because the slope of the position-time graph (which gives the velocity) is indeed tangential to the path of the object at any point. - Thus, we conclude that both statements are true and that Statement 2 provides a correct explanation for Statement 1. ### Final Answer: Both statements are true, and Statement 2 is a correct explanation of Statement 1. ---
