In a two-sector economy model, the economy is simplified to two main sectors: households and firms. 1. Households:
Households own the factors of production, such as land, labor, capital, and entrepreneurship. They provide these factors to firms in exchange for income, which includes wages, rents, interests, and profits. 2. Firms:
Firms are the producers of goods and services. They use the factors of production from households to produce goods and services, which are sold to households. In return, firms pay income to households for their factors of production. - Flow of Income and Expenditure:
- Households spend their income on the goods and services produced by firms (Consumption Expenditure).
- Firms, in turn, provide goods and services to households in exchange for payment, which is their revenue. - Circular Flow:
- The flow of goods and services from firms to households and the flow of income from households to firms forms a continuous cycle, known as the circular flow of income. - Equilibrium in the Circular Flow:
The economy reaches equilibrium when total income generated in the economy (from the sale of goods and services) is equal to the total expenditure (households' consumption expenditure).
Conclusion: In a two-sector model, the economy functions as a closed loop where households provide factors of production to firms, and firms return income to households in exchange for goods and services.

The 12 musical notes are given as \( C, C^\#, D, D^\#, E, F, F^\#, G, G^\#, A, A^\#, B \). Frequency of each note is \( \sqrt[12]{2} \) times the frequency of the previous note. If the frequency of the note C is 130.8 Hz, then the ratio of frequencies of notes F# and C is:
