Question

Match the Column I with Column II.

	Column I (Physical quantity)		Column II (Formula)
(A)	Instantaneous velocity, $v=$	(p)	$\frac{\Delta x}{\Delta t}$
(B)	Average velocity, $\bar{v}=$	(q)	$\displaystyle \lim_{\Delta t\to 0}$$\frac{\Delta v}{\Delta t}$
(C)	Instantaneous acceleration, $a =$	(r)	$\frac{\Delta v}{\Delta t}$
(D)	Average acceleration, $\bar{a}=$	(s)	$\displaystyle \lim_{\Delta t\to 0}$$\frac{\Delta x}{\Delta t}$

• A. $A - p$, $B - q$, $C - r$ , $D - s$
• B. $A - r$, $B - s$, $C - p$, $D - q$
• C. $A - s$, $B - p$, $C - q$, $D - r$
• D. $A - q$, $B - r$, $C - s$, $D - p$

Answer 1

Answer: (C)

Instantaneous velocity, $\displaystyle \lim_{\Delta t \to 0}$$\frac{\Delta x}{\Delta t}$; $A-s$
Average velocity, $\bar{v}=\frac{\Delta x}{\Delta t}$; $B-p$
Instantaneous acceleration, $a=$ $\displaystyle \lim_{\Delta t \to 0}$ $\frac{\Delta v}{\Delta t}$; $C-q$
Average acceleration, $\bar{a}=\frac{\Delta v}{\Delta t}$; $D-r$
