Colonialism and the City 

Colonialism and the City - CBSE Class 8 - History - NCERT Q and A (#cbsenotes)(#eduvictors)

Q & A

Important points:

The partition of India in 1947 led to a massive transfer of populations, and Delhi became a city of refugees.

While Old Delhi was almost ignored by the British, millions were spent on developing New Delhi.

In the late 18th century, Calcutta, Bombay, and Madras became the centres of British colonial power.

In 19th century, in most parts of the Western world, modern cities emerged with industrialisation, but Indian cities under British rule did not benefit much.

After 1911, Delhi became the capital of British India. New Delhi took nearly 20 years to build.


Q1: State whether true or false:
(a) In the Western world, modern cities grew with industrialisation.
(b) Surat and Machlipatnam developed in the nineteenth century.
(c) In the twentieth century, the majority of Indians lived in cities.
(d) After 1857 no worship was allowed in the Jama Masjid for five years.

CBSE Class 10 - Pair of Linear Equations In Two Variables - Solved Examples (#cbsenotes)(#eduvictors)

☛Following questions have been asked in previous years of CBSE board examination.

Q1: Solve the following system of linear equations by elimination method (equating the coefficients).
6 (ax + by) = 3a + 2b
6 (bx – ay) = 3b – 2a

Answer:

Given equations :
6 (ax + by) = 3a + 2b ...(1)
6 (bx – ay) = 3b – 2a ...(2)

multiply eqn. (1) by a and equation (2) by b, and add, we get

6a²x + 6aby = 3a² + 2ab
6b²x – 6aby = 3b² – 2ab
────────────────────────
6 (a² + b²)x = 3(a + b)
────────────────────────

⇒ x = ½

Put x = ½ in equation (1), we have

6a × ½ + 6by = 3a + 2b

6by = 2b
y = ⅓

∴ x = ½ and y = ⅓        (Answer)

Introduction To Euclid's Geometry - Axioms, Theorem and Other terms


(Note: Following list is compiled from a very old book 'Elements of Geometry by Ledegenre' and other NCERT textbooks)

Important terms to remember:

1. An axiom is a self-evident proposition (an assumption which is a self-evident truth).

2. A theorem is a truth, which becomes evident by means of a train of reasoning called a demonstration or proof. Theorems are proved, using axioms, previously proved statements and deductive reasoning.

3. A problem is a question proposed, which requires a solution.

4. A lemma is a subsidiary truth, employed for the demonstration/proof of a theorem, or the solution of a problem.

Introduction to Trigonometry

CBSE Class 10 - Maths - Introduction to Trigonometry - Short Q and A (#cbsenotes)(#eduvictors)

Short Q and A 

Q1: If sin 3A = cos (A – 26°), where 3A is an acute angle, find the value of A.

Answer: sin 3A = cos (A – 26°)

∵ sin 3A = cos (90° – 3A)
∴ cos (90° – 3A) = cos (A – 26°)

Since
90° – 3A and A – 26° are both acute angles, therefore,
90° – 3A = A – 26°
A = 29°

Q2: Express cot 85° + cos 75° in terms of trigonometric ratios of angles between 0° and 45°.

Answer: cot 85° + cos 75° = cot (90° – 5°) + cos (90° – 15°)

= tan 5° + sin 15°

Q1: Explain why nomadic tribes need to move from one place to another. What are the advantages to the environment of this continuous movement?

Answer:  There were many need of nomadic tribes to move from one place to another:

① The nomadic tribes had no regular fields of their own from where they could get fodder for their cattle.

② They lived with their herd in the low hills of the Himalayas from September to April because; the huge mountains or high altitudes were covered with snow during this period. In these areas, the dry scrub forests provided pastures for their herds during this period.

③ With the onset of summer, as the snow melted and the hillsides began to be covered with lush green with a variety of new grasses, the pastoralists started their northward march for their summer grazing grounds.

④ Again with the onset of winter when the mountains began to be covered with snow and there was a dearth of nutritious forage, these pastoralists on the move again, this time on their downward journey.

The movement of the nomadic pastoralists from the downward to the upward areas and vice-versa allowed sufficient time for natural restoration of vegetation grounds. Their continuous shifting provided sufficient forage to the different animals both at the high mountains and the lower hills. They also helped in maintaining the quality of the pastures.
