Explanation

Let's break it down step by step:

1. (√9²+12²) = √(81+144) = √225 = 15

2. (-3)² = 9

3. 15 + 9 = 24

4. (-1 + 2 + 3) = 4, and 4³ = 64

5. 24 - 64 = -40

6. ³√-125 = -5 (since (-5)³ = -125)

7. -40 - (-5) = -40 + 5 = -35

Explanation

The empirical formula shows the simplest whole-number ratio of atoms in a compound (e.g., CH₂O for glucose).

It does not reflect the actual number of atoms like the molecular formula does, just their simplest ratio.

Explanation

A magnetic field exerts a force perpendicular to the motion of the charged particle, changing its direction but not its speed.

Since no work is done by the magnetic field, the kinetic energy stays constant.

Explanation

A syllabus is a document that outlines the topics, objectives, and structure of a subject or course.

It guides both teachers and students on what content will be covered during a specific academic period.

Explanation

Electromagnetic spectrum order (longest to shortest wavelength):

Radio waves (includes TV signals) → Infrared → Visible light → X-rays.

It follows this order, starting with television (radio waves) and ending with X-rays.
