Question

Q1. The minute hand of a clock is 14 cm long. Find the displacement and distance covered by it from (i) 7:00 am to 7:30 am (ii) 10:00 am to 11:00 am.
$please \: give \: correct \: answer$


​

Answer 1

From 7:00 to 7:30

since Peremeter of clock is

$2\pi</em><em> </em><em>r$

since circle is half

$\pi</em><em> </em><em>r$

3.14*0.4=1.3

from 10:00to 11:00

since distance is 1.3*2=2.6

but displacement is zero because it come back to its initial point
