Explanation

A ∩ (C U B) = (A ∩ B) U (A ∩ C)

Explanation

Explanation

• In semiconductors, as the temperature increases, the conductivity increases.
• This is because heat energy excites more electrons into the conduction band, allowing them to flow more freely and increasing the conductivity.
• This is in contrast to metals, where conductivity typically decreases with increasing temperature.

Explanation

Machine language is the lowest-level programming language, consisting of binary code that a computer's processor can execute directly. The basic components of a machine language program are:

• Instructions: These are the fundamental commands that a computer's processor can execute, such as move data, perform arithmetic operations, jump to a location, etc. Instructions are represented as binary codes, such as 0s and 1s.

Explanation

• Triethylamine (N(CH₂CH₃)₃) is a tertiary amine, which is a type of amine that has three organic groups attached to the nitrogen atom.
• In this case, the three ethyl groups (CH₂CH₃) are attached to the nitrogen atom.

Explanation

The expression is a variation of the trigonometric identity:

cos^2(x) + sin^2(x) = 1

In this case, the expression is:

cos^2(θ/2) + sin^2(θ/2)

Using the identity, we can simplify the expression to: 1

Explanation

• Velocity is the speed of a body in a specific direction.
• It is a vector quantity, which means it has both magnitude (amount of movement) and direction.

Explanation

• A truant is a child who stays away from school without a valid reason or excuse, often habitually or repeatedly. This behavior is known as truancy.
• Delinquent refers to a young person who commits a crime or misbehaves.
• Schizophrenic refers to a person with a mental disorder characterized by hallucinations, delusions, and disorganized thinking and behavior.
• Vagabond refers to a person who wanders from place to place without a fixed home or regular means of support.

Explanation

• A microphone converts sound waves into electrical signals, which are analogue in nature.
• The voltage signal generated by a microphone is a continuous signal that varies in amplitude and frequency in response to the sound waves.
• This signal is an analogue representation of the sound wave, and it is not digital.
