The only way the bag of apples can have zero acceleration is that the sum of forces on it is zero. The 20-N downward gravitational force on it must be exactly canceled by some upward force of 20-N. That's the tension in the rope.
The tension at every point in the rope must be 20N, and it must exert 20N of upward vertical force on the top of the bag. If there's any point in the whole arrangement where the upward and downward forces are not exactly equal, then the mass at that point must be accelerating up or down.
it acts along the surface of liquid

At rest, tension in the string and weight of the bob are the two forces both equal and opposite. During its displaced position, the weight of the bod, tension of the string and restoring force all the three would act on it

20 N, N is a weight(Force) therefore gravity is already included.
Four apples unless it is intentionally a trick question and the rest doesn't count as apples- then it would be two and a crappy example of a logic question.
YES. eat nothing but apples the rest of your life.
Increasing the duration of the rest period increased the duration of the subsequent maximal tension.
