Atomic absorption spectroscopy (AAS) is a analytical technique used to measure the concentration of specific metallic elements in a sample by detecting the

amount of light they absorb in the gaseous state .

How It Works

Atomization: The liquid or solid sample is vaporized and converted into free ground- state atoms using a heat source like a flame or graphite furnace. 

Light Absorption: A hollow-cathode lamp shines a specific wavelength of light characteristic of the target element through the

Q2. “The main goal of E-Governance is to provide SMART government.” Justify the statement.

== SMART = Simple, Moral, Accountable, Responsive, Transparent

== Simple: Makes government services easy and accessible. // Moral: Helps reduce corruption and misuse of power. // Accountable: Government activities can be monitored.// Responsive: Provides quick response to citizens. // Transparent: Makes government information and processes open.

Thus, E-Governance helps create a SMART, efficient and citizen-

The title Pride and Prejudice is perfectly chosen because it highlights the core flaws of the main characters and drives the entire plot of Jane Austen’s novel.For a standard 5-mark examination answer, you can structure your response into five clear, concise points (1 mark each):1. Reflection of Main CharactersThe title directly points to the two primary protagonists: Mr. Darcy and Elizabeth Bennet.Mr. Darcy embodies pride due to his high social standing and immense wealth.Elizabeth Bennet exhibits

2. Explain Understanding AI based on thought process and behavior with example.

== Artificial Intelligence (AI) can be understood based on thought process and behavior in four ways: // Thinking Humanly: AI tries to think like a human being.
Example: A chatbot understanding a user's question and giving a human-like response. /// Thinking Rationally: AI uses logical reasoning to reach a conclusion.
Example: An expert system using medical rules to identify a disease. /// Acting Humanly: AI performs actions

1. PRIME FACTORISATION, HCF, AND LCM

• Prime Factorisation:

  • Breaking a number down into a product of its prime factors (usually using factor trees).

  • Example: 60 = 2 × 2 × 3 × 5 = 2² × 3 × 5.

• Highest Common Factor (HCF):

  • The largest factor that divides two or more numbers.

  • Method (Venn Diagram): Multiply the numbers found in the intersection (overlap) of the prime factor sets.

• Lowest Common Multiple (LCM):

  • The smallest multiple shared by two or more numbers.

  • Method (Venn

Q1. Define Primary Key and Candidate Key. A Candidate Key is a minimal set of attributes that can uniquely identify a tuple. A Primary Key is the candidate key chosen by the designer to uniquely identify records in a table (cannot be NULL).

Q2. What is Referential Integrity constraint? It ensures that a foreign key value in one table must either match a primary key value in the referenced table or be NULL — maintaining consistency between related tables.

Q3. What is Entity Integrity constraint?
