Shang Dynasty (c. 1600–1046 BCE) – First historically confirmed Chinese dynasty centered along the Yellow River. Known for bronze metallurgy, oracle bones, urbanization, and ancestor worship, ruled by kings claiming divine authority.
Oracle Bones (c. 1200 BCE) – Animal bones or turtle shells used for divination during the Shang dynasty. Questions were inscribed, heated, and the cracks interpreted; they contain the earliest known Chinese writing.
Mandate of Heaven (Tianming) – Zhou-era political

API (Application Programming Interface): collection of predefined classes, interfaces, methods (libraries). Java is a simple (easy to learn), object-oriented (uses objects and classes), distributed (supports network-based applications), and interpreted (runs via JVM from bytecode) language. It is robust (strong in error handling and memory management), secure (protects against threats with built-in
...Inheritance in Python
Inheritance allows a class to use and extend the properties and methods of another class.
It promotes code reusability and reduces duplication.
Think of it as “child learns from parent.” 👨👦💻
Program with no Inheritance:
import datetime
class TennisPlayer:
def __init__(self, fname, lname, birth_year):
self.first_name = fname
self.last_name = lname
self.birth_year = birth_year
self.aces = []
def get_age(self):
now = datetime.datetime.now()
return now.year - self.birth_
Sericulture is the rearing of silkworms for the production of silk. It is a farm-based, labor-intensive, and commercially profitable agro-industry that provides employment and income to rural people, especially women and small farmers.
Main scopes include:
1. Employment generation: Provides year-round jobs to farmers, reelers, weavers, and traders.
2. Rural development: Boosts the rural economy through cottage industries.
3. Export potential: India earns valuable foreign exchange through export

Q: Write R code to create a vector v with elements 3, NA, Inf, and -Inf. Then, explain what happens if you add 5 to v.
A:v <- c(3, NA, Inf, -Inf). Adding 5: v + 5 outputs [1] 8 NA Inf -Inf. NA propagates (remains NA), Inf + finite = Inf, -Inf + finite = -Inf (from specialvalues.html: arithmetic with Inf behaves sensibly, but NA is "not available").
Q: Given vector a <- c(10, 15, NA, 20), write code to count NAs and replace them with the

A single-phase induction motor is a widely used AC motor in domestic and commercial appliances. It works on the principle of electromagnetic induction and has a simple and rugged construction similar to a three-phase squirrel cage induction motor.
Stator:
The stator is a stationary part made of laminated steel to reduce eddy current losses.
A single-phase winding is placed in slots distributed around the stator
