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 $(t_1)$
