20 N.

20 N

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.

Same 20 N

20 N, N is a weight(Force) therefore gravity is already included.

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.

YES. eat nothing but apples the rest of your life.

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.

Increasing the duration of the rest period increased the duration of the subsequent maximal tension.

Apples are awsome
