Explanation

The relation between work (W) done and torque (τ) in rotational motion is:

W = τdθ

Where:

- W is the work done

- τ is the torque

- dθ is the angular displacement

This shows that work done in rotational motion is the product of torque and angular displacement.

Explanation

The microscopic form of Ohm's law is:

J = σE

where J is the current density.

σ is the conductivity.

E is the electric field.

Explanation

Active learning involves students engaging in problem-solving, critical thinking, and application of knowledge.

It goes beyond passive listening, making learning more interactive and effective.

Explanation

Communication between a keyboard and computer is simplex, meaning data flows in one direction only — from keyboard to computer.

The computer does not send data back to the keyboard during typing.

There are 3 main data transmission modes:

1. Simplex: Data flows in one direction only (e.g., keyboard to computer).
2. Half-Duplex: Data can flow both ways, but not at the same time (e.g., walkie-talkies).
3. Full-Duplex: Data flows both ways simultaneously (e.g., telephone conversations).

Explanation

A gateway is a device that connects two or more networks using different communication protocols.

It acts as a translator between systems so they can communicate effectively.

Explanation

A warm boot refers to restarting a computer without turning off the power (e.g., using Ctrl + Alt + Del or the restart option).

In contrast, a cold boot means starting the computer after it has been completely powered off.

Explanation

The National Council for Teacher Education (NCTE) is responsible for regulating and maintaining quality in teacher education.

It ensures colleges meet required standards for training teachers effectively.

Explanation

According to Iqbal’s philosophy, a student should think independently and not just accept others’ viewpoints blindly.

This emphasizes self-thinking and personal understanding rather than following others.

Explanation

"What he attempted" acts as the object of the verb "in" — it tells what he failed in.

Since it functions like a thing or idea, it's considered a Noun Phrase.
