A min. hand of a clock is 7cm long calculate the distance covered and displacement of min. hand from 9am to9:30am |
|
Answer» ANSWER: distance = 77 cm and DISPLACEMENT = 14 cm Explanation: Distance covered = 1/2 TIMES the circumference of the CLOCK => 1/2 * πr² where r = radius of the circle = length of the minute hand => distance covered = 1/2 * 22/7 * 7 * 7 = 11 * 7 = 77 cm Displacement = 2 * radius = 2 * 7 = 14 cm Therefore distance = 77 cm and displacement =14 cm Please brainlist my answer, if helpful! |
