Question

the min hand of a wall clock is 10 cm long. find its displacement and distance covered. from 10 am to 10:30am​

Answer 1

Answer:

distance = 31.4 cm

displacement = 20 cm towards south.

Explanation:

Assume that a wall clock is a circle.

Then the radius is 10cm.

So the distance is the circumference of semi circle.

That is ( pie ) x radius.

So the distance travelled is 3.14 x 10 =31.4cm.

And the displacement is the diameter.

That is 2R.

That is 20cm towards south.
