Question

Let $x_{1}$ and $x_{2}$ be the positions of an object at time $t_{1}$ and $t_2$ Then, its displacement, denoted by $A,$ in time $\Delta t=B$, is given by the difference between the $\mathrm{C}$ and $\mathrm{D}$ position. Here $A, B, C$ and $D$ refer to
Answer the following question based on given figure.

• A. $ A \to \Delta x, B \to t_1 - t_2, C \to final, D \to initial $
• B. $A \to \Delta x, B \to t_2 - t_1 C\to final, D \to initial $
• C. $ A\to x, B \to t_2-t_1 C\to initial, D \to final $
• D. $A \to \Delta x, B \to - t_2 - t_1 C \to initial, D\to final $

Answer 1

Answer: (B)

Displacement is denoted by $\Delta X $ in time $\Delta t = t_2 - t_1 $ is given by the difference between final position $(t_2) $ and initial position $(t_1) $
