Answer 1

Answer:

In the given sentence, the object travels from one side to the other side of the semi-circle. So, the displacement achieved is 2 times the radius which is the diameter.

Diameter = 2 * 7 m = 14 m

Therefore, your answer is 14 m.

Answer 2

Answer:

Plzzz mark brainliest.

Explanation:

As U know;

Distance is the total distance travelled by the body whereas Displacement is the shortest path b/w initial and final points.

Here in the above questions,

Distance travelled would be the path travelled that is the semicircular path . This length could be calculated in the following way;

Distance = Circumference / 2

Distance = 2πr/2

Distance = (22 / 7) X 7m

Distance = 22m

Whereas the displacement is the shortest path here, which is the diameter here .

Displacement = 2r

Displacement = 2 X 7

Displacement = 14m
