| D | Motion of skin of tabla | Child playing in a play ground | A flying bird |
Ans 1:
Class : Class 8
To and Fro motion of a swing is ONLY PERIODIC if the speed stays the same which is VERY unlikely
Ans 4:
Class : Class 6
the answer would be C as the hands of the clock shows rotational and periodic motion whereas the table top shows only rotational motion
Ans 5:
Class : Class 6
Answer should be c. It cannot be A as the motion of moon around earth is not rotational. it is circular
Ans 6:
Class : Class 10
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
