Study the given Venn diagram. Which of the motions described by different bodies are most likely to be I, II and III?
|A||Hands of clock||Motion of moon around the earth||The blades of a fan|
|B||Motion of a top||The wheels of a bullock cart||Ball moves around its centre|
|C||To and fro motion of a swing||Hands of a clock||Motion of a top|
|D||Motion of skin of tabla||Child playing in a play ground||A flying bird|
the answer would be C as the hands of the clock shows rotational and periodic motion whereas the table top shows only rotational motion
Answer should be c. It cannot be A as the motion of moon around earth is not rotational. it is circular
first thing , both option 1 and 3 have oone mistakein option a - a fan moving is wrong as it is circulatoryin option c - to and fro movement of swing is wrong as the swing may not swing at the same angle every timeDear,SOF , do not go mad!!!!!!!!!there are better trainers than you like- olympiad helper, olympiad succes, online test series (allen)so do not be proud
