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, v̄ =	(q)	$\lim_{\Delta t \rightarrow 0}\frac{\Delta v}{\Delta t}$
(C)	Instantaneous acceleration, a =	(r)	$$\frac{\Delta v}{\Delta t}$$
(D)	Average acceleration, a =	(s)	$$\lim_{\Delta t \rightarrow 0}\frac{\Delta x}{\Delta t}$$

• 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)

A – s, B – p, C – q, D – r

Answer 2

Instantaneous velocity, $v = \lim_{\Delta t \rightarrow 0}\frac{\Delta x}{\Delta t}$

A – s

Average velocity, $\overline{v} = \frac{\Delta x}{\Delta t}$

B – p

Instantaneous accelerations, $a = \lim_{\Delta t \rightarrow 0}\frac{\Delta v}{\Delta t}$C – r

Average accelerations, $\overline{a} = \frac{\Delta v}{\Delta t}$ D – r
