### Physics Problem: Analyzing Forces with a Spring Scale

#### Problem Description

**Scenario (a)**:
A 2.29 kg salami is suspended by a cord running to a spring scale, which is further supported by another cord from the ceiling. Determine the reading on the scale, indicated in weight units (N - Newtons).

**Scenario (b)**:
In this setup, the salami hangs from a cord that goes over a pulley to the spring scale, and the opposite end of the scale is attached by a cord to a wall. Calculate the scale reading in this configuration.

**Scenario (c)**:
The wall from scenario (b) is replaced with another 2.29 kg salami, creating a symmetrical system. With the assembly stationary, determine the new reading on the scale.

#### Diagrams Explanation

- **Figure (a)**: Displays a vertically hanging salami attached to a spring scale. The salami’s weight is the only force acting downwards, countered by the tension in the cord.
- **Figure (b)**: Illustrates the setup involving a pulley, where the salami’s weight is balanced by the tension in the cord, connected to a wall.
- **Figure (c)**: Two salamis are suspended symmetrically on either side of the table, each attached to the spring scale. This setup creates equal and opposite forces.

#### Scale Readings

- **(a)**: 2.44 N
- **(b)**: 2.44 N
- **(c)**: 4.88 N

The spring scale readings reflect the balance of forces in each scenario, considering the gravitational force acting on the salamis.
