It's 20N IF the bag is just hanging there and not moving.
If the bag is rising or falling, then the tension can be, but isn't necessarily,
more or less than 20N.
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.
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.
the weight of the solid thing acting on the swing courses the swing to tension( courses it to pull apart)this how it acts on a swing
The direction of tension in a rope always runs both ways and parallel to the rope.

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