Answer 1

A gentle word, a kind look, a good-natured smile can work wonders and accomplish miracles.

Answer 2

Answer:

1l No, because the boy is not moving along a circular path and the distance of the boy from the centre of the park does not remain same.

2) the action or process of moving or being moved.

3) Periodic motion : A motion which gets repeated after regular intervals of time is called a periodic motion.

Examples : The earth moving around the sun takes 365 days to complete one revolution and this motion gets repeated after every 365 days.

Non-periodic motion : The motion which does not repeat itself after regular interval of time is called non-periodic motion.

Examples : A footballer running on a field, application of brakes in a moving vehicle, a ball rolling down the ground gradually slows down and finally stops, motion of tides in the sea, etc.
