Question

The length of the minute hand is 14 cm find its distance and displacement after 30 minutes and 10 minutes

Answer 1

Answer:

176 cm

Explanation:

The minute hand will cover two rounds from

5:20pm to 7:20pm.

Distance travelled by the tip of minute hand=

2×(Circumfrence of the circle whose radius is 14cm.)

=2×(2×pi×r)

=2×2×(22/7)×14 cm.

=4×22×2 cm.

$\boxed{=176 cm}$

Displacement = 0 ( initial position and final  position of the tip is same).
