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