A Bird sitting on a wire, flies, circles around and comes back to its perch. Explain the total distance it traversed during its flight and its eventual displacement.

Fill in the blanks with the proper words from the brackets: When an object comes back to the point of origin, its displacement is_____.

A point object moves along an arc of a circle or radius'R' . Its velocity depends upon the distance covered 'S' as V=KsqrtS Where'K' is a constant. IF theta is the angle between the total acceleration and tangential accleration , then

Two full turns of the circular scale of a screw gauge cover a distance of 1 mn on its its main scale . The total number of divisions on the circular scale is 50. Further m it is found that the screw gauge has a zero error of - 0.02 mm . While measuring the diameter of a thin wire , a student notes the main scale reading of 4 mm and the number of circular scale divisions in line with the main scale as 37. The diameter of the wire is
