Answer 1

A snowball that rolls down a hill, gradually gaining more and more mass and rolling faster and faster as it continues, would be an example of a Positive feedback system.

What is Positive feedback system?

When the fed-back signal is in phase with the input signal there occurs the positive feedback for a system.

Under certain gain conditions, positive feedback reinforces the input signal to the point where the output of the device oscillates between its maximum and minimum possible states.

For example, when part of an supplied electronic output signal returns to the given input, and if is in phase with it, the system gain is increased.

There, the positive feedback occurs.

As here, A snowball that rolls down a hill, gradually gaining more and more mass and then the process continues.
