​

Answer 1

Answer:

Distance is 40 cm

Disolacement is zero

Answer 2

Answer:

DISPLACEMENT = 0 cm

DISTANCE = 40 cm

Explanation:

DISTANCE IS THE TOTAL PATH TRAVELLED BY AN OBJECT HERE THE CIRCUMFERENCE OF THE CIRCLE IS THE DISTANCE TRAVELLED.

WHERE'S DISPLACEMENT IS THE SHORTEST STRAIGHT LINE PATH BETWEEN INITIAL AND THE ENDING POINT AS YOU CAN SEE THE PERSON WENT BACK TO THE SAME POINT WHERE HE STARTED, SO HIS INITIAL STARTING POINT AND ENDING POINT'S ARE SAME .

THEREFORE, DISPLACEMENT IS EQUAL TO ZERO .
