Question

the minute hand of clock is 7 cm calculate distance and displacement from 9:30 to 10;00

Answer 1

hope this helps you......

Answer 2

Hii friend,

Here is your answer....

Distance travelled by any object in circular is equal to the total circumference of the circle

distance= 2πr

Here the clock travelled for half an hour. So the distance it's equal to half of circumference.

:- Distance =πr

{π =22/7}

Distance = 22/7×7

Distance =22 cm.........(1)

Displacement is the shortest distance travelled by an object.

Displacement =2y
y=7 cm

Displacement =2×7

Displacement = 14cm...........(2)

Hope this helps you a little!!!
