1. The noun is a word expressing substance in the widest sense of the word. This includes names of living beings, of lifeless things, of abstract notions (qualities, states, actions).The noun can be formed by means of suffixes and prefixes.  Productive noun we form by means of such suffixes as: -er (to read - reader) -ist (to specialize - specialist) -ness (careless - carelessness)

-ism (national - nationalism) -ess (traitor - traitress). It is practically the only gender-forming suffix, expressing

 (a) Radius of Gyration (k)
The radius of gyration of a body about a given axis is the radial distance from the axis of rotation to a point where the entire mass of the body could be concentrated without changing its moment of inertia.
Mathematically, it is defined by the relation:

Where:
 * I is the moment of inertia.
 * M is the total mass of the body.
 * k is the radius of gyration (SI unit: meters).
(b) Can Poisson's Ratio be Negative?
Yes, the Poisson's ratio (\sigma) of a material can be negative.

Modelo Bioecológico do Desenvolvimento Humano – Bronfenbrenner

Constitui um referencial teórico fundamental para compreender o desenvolvimento como um processo dinâmico e contextualizado, resultante da interação contínua entre o indivíduo e os múltiplos contextos em que se insere. Esta perspetiva afasta-se de abordagens exclusivamente centradas no indivíduo, enfatizando o papel determinante do meio ambiente e das relações estabelecidas ao longo do tempo.

1. Folds: Bending of Rock Layers

Folds are wave-like undulations in rock strata. They are most common in sedimentary rocks.

Origin (Mechanism)

Folds originate primarily due to Compressional Stress. When rocks are pushed together, they shorten and thicken.

• Ductile Deformation: Folds form deep within the crust where high temperature and pressure allow rocks to bend without breaking.

• Tectonic Forces: Major fold belts (like the Himalayas) originate from the collision of tectonic plates.

Classification

1) Binary to Decimal Conversion

To convert a binary number to decimal, multiply each bit by its place value (2⁰, 2¹, 2², etc.) then add the results.
Example: 1011₂ = (1×2³) + (0×2²) + (1×2¹) + (1×2⁰) = 8 + 0 + 2 + 1 = 11 (decimal).

✅ 2) Advantages of Universal Gates

Universal gates are NAND and NOR gates. Their advantage is that any logical function can be implemented using just one type of gate. This makes design simpler, reduces manufacturing cost, and increases flexibility in

(a) What is a Number System?

A number system is a way of representing numbers using a set of symbols and a base (radix).
Examples:

Decimal (base 10)

Binary (base 2)

Octal (base 8)

Hexadecimal (base 16

b) Why Digital Computers use Binary Number System?

Digital computers use binary because:

Electronic circuits have two states: ON (1) and OFF (0)

Binary is reliable and easy to implement

Less error in data processing

(c) Convert (1001.0010)₂ to Decimal

Integer part:
10012=1×23+0×22+0×21+1×20=91001₂
