Activity:-
To observe deflection of a magnetic needle placed near a conductor carrying current.
Apparatus and materials:
Magnetic needle, battery, ammeter, rheost, key, conducting wire etc.
Theory:
When electric current passes through a conductor magnetic field is produced around it.
Procedure:
(1) Magnetic substances are removed from the table and the magnetic needle is placed on it. The cell, rheostat, key and ammeter are connected in series with the experimental wire as shown in Fig. 37. The
To observe the variation of potential difference (V) across a given resistance with varying current (I) and draw I-V curve and find the value of a given resistance from graph.
Apparatus and materials:
Battery, ammeter, voltmeter, resistance, rheostat, key, connecting wires and sand paper.
Theory:
Ohm's law states that the temperature remaining constant the current (1) flowing through a conductor is proportional to the voltage (V) across it. Thus,
I∞V
or, V = IR
where R is called the resistance
Natural Language Processing (NLP) is a branch of Artificial Intelligence (AI) which helps computers to understand, analyze and generate human language (text or speech).
NLP is a bridge between human language and computer language.
Machine Translation converts text from one language to another automatically using NLP.
Example: Google Translate
Use: Helps people communicate in different languages.
Romanen När hundarna kommer av Jessica Schiefauer handlar inte bara om brott, sorg och skuld, utan också om relationer och hur kärlek kan förändras till något destruktivt. Ett av de tydligaste temana i boken är kärlek och beroende, som framför allt skildras genom relationen mellan Ester och Isak. Deras förhållande börjar som en intensiv och romantisk tonårskärlek, men utvecklas gradvis till ett osunt känslomässigt beroende. I stället för att relationen ger trygghet och

EXPLAIN CYBER TECHNOLOGY.
ANS:- Definition
Cyber Technology refers to the use of computer systems, networks,
software, and the Internet to create, store, process, transmit, and
protect digital information. It forms the technological foundation of
activities performed in cyberspace.
Explanation
Cyber Technology enables communication, data sharing, online
services, and digital transactions over interconnected networks. It
supports modern applications such as e-commerce, e-governance,
online banking, cloud
PRINCIPLES OF BLOCKCHAIN
Principle 2: Immutability – Once data is recorded on the blockchain, it cannot be altered or deleted, ensuring data integrity.
Principle 3: Transparency – All transactions are visible and verifiable by network participants, promoting trust and accountability.
Principle 4: Security – Cryptographic

...Diphenhydramine HCl synthesis t
Common Synthesis Route
1. *Starting materials*: Benzhydrol and 2-(dimethylamino)ethanol.
2. *Reaction*: Benzhydrol is reacted with 2-(dimethylamino)ethanol in the presence of an acid catalyst (like HCl or sulfuric acid) to form diphenhydramine.
3. *Formation of HCl salt*: Diphenhydramine base is then converted to its HCl salt for stability and solubility.
Process
- *Step 1*: React benzhydrol with 2-(dimethylamino)ethanol under acidic conditions.
- *Step 2*: Form the
