Question

Which of the following can sometimes be ‘zero’ for a moving body?i. Average velocityii. Distance travellediii. Average speed iv. Displacement
2 points
a) Only (i)
(b) (i) and (ii)
(c) (i) and (iv)
(d) Only (iv)​

Answer 1

$\red{ \: here \: is \: ur \: answer}$

●●option d ) is the correct answer

■》 average velocity can never be zero
because---

$\blue{ \:average \: velocity \: = \: \frac{total \: displacement}{total \: time \: taken}}$
since displacement is a vector quantity , it
can be zero but total time taken can never
be zero and hence, average velocity also
can't be zero...

■》 Distance is a scalar quantity and is always
positive so, can't be zero


■》
$\blue{ \: average \: speed \: = \: \frac{total \: distance}{total \: time}}$
since, distance and time can never be zero
thus, zero value of average speed is also
impossible ....
