How are they different?
Type of changes
Fast and slow
Examples
Periodic and non-period
Answers
Answer:
The changes which take place in a long period of time are called slow changes whereas that changes which take place in a short period of time are called fast changes.
Examples:
(a) Rusting of iron, formation of day and night, ripening of fruits, growing of trees are slow changes.
(b) Burning of paper, stretching of rubber band, blowing of balloons, bursting of crackers are fast changes.
periodic and non periodic
A periodic signal is one that repeats the sequence of values exactly after a fixed length of time, known as the period. ... A non-periodic or aperiodic signal is one for which no value of T satisfies Equation 10.11. In principle this includes all actual signals since they must start and stop at finite times.
Answer:
A change is the transition of any substance
from one form to another.
The changes taking place around us can be
classified as
Slow and fast change
Useful and harmful changes
Natural and man-made changes
Periodic and non-periodic changes
Reversible and irreversible changes
Fast and slow changes
Some changes – like the germination of a seed
to form a plant, the growth of a child into an
adult and further into an old man, and the
rusting of iron – take place very slowly and take
a long time to occur. Such changes, which take
a long time to occur, are called slow changes.
Explanation:
On the other hand, some changes take place
fast, that is, in a short period of time.
Such changes are called fast changes.
Examples
The burning of paper, bursting of crackers and
glowing of a bulb are examples of fast changes.
Changes that repeat at regular intervals are
called periodic changes.
Examples: The occurrence of day and night and
the waxing and waning of the moon.
Certain changes that do not repeat themselves
at regular intervals of time, and such changes
are called non-periodic changes.
Examples:Changes such as freezing of water,
falling of leaves from trees and landslides
during the rainy season are non-periodic
changes.
