Answer 2

Given:

The linear speed of second hand of wall clock is 1cm/s.

To Find:

We are asked to find the length of the second hand is nearly equal to

Solution:

By considering the given data,

Time taken to complete one round by second hand,

$T=\frac{2\pi r}{v}$

$T=\frac{2\pi r}{1 cm/s} =60 sec$

The length of second hand is given by,

$r=\frac{vt}{\pi } =\frac{10^{-2}m/s * 60 s }{2*3.14}$

$r=0.095m$

Hence the length of the second hand is nearly 0.095m
