Scale 1:50 → 1 cm on plan = 50 cm = 0.5 m in reality.

Actual length = \(4 \times 50 = 200\ \text{cm} = 2\ \text{m}\

Actual width = \(3 \times 50 = 150\ \text{cm} = 1.5\ \text{m}\

Actual area = \(2 \times 1.5 = \mathbf{3\ \text{m}^2}\

• Mg has a full 3s² subshell (extra stability)
• Al's 3p electron is shielded by 3s electrons and easier to remove

The text explicitly states that it is estimated that two-thirds ($\frac{2}{3}$) of the jobs eliminated in the 1990s were supervisory/middle management jobs, reflecting the flattening of organizational structures.

Stereotyping in mass communication refers to the application of pre-formed, generalised assumptions about members of a group — based on race, gender, age, religion, nationality, profession, or social class — to all members of that group. The textbook explains that media stereotypes are “sometimes inevitable, especially in advertising, entertainment and news industries, which need as wide an audience as possible to quickly understand information.” However, the danger is profound:

• Stereotypes reduce complex individuals to simplified caricatures
• When repeated frequently, they transform assumptions into perceived realities
• They can cause measurable psychological harm — the textbook's case study on beauty stereotyping in media linked media images to depression, eating disorders, and loss of self-esteem in women and girls
• Stereotypes perpetuate discrimination by associating entire groups with negative or limiting characteristics

The textbook argues that media professionals must be educated about stereotyping to reduce its harmful use.

Lenz's law: induced current opposes the change in flux.

Paralytic ileus is the temporary cessation of bowel motility after abdominal surgery. Return of bowel function is confirmed by:

1. Passage of flatus (gas) — earliest and most reliable sign of return of peristalsis
2. Bowel sounds (return in small bowel first, usually 24–48 hrs; large bowel 48–72 hrs)
3. Passage of stool

Assessment sequence for bowel function return:

• Auscultate for bowel sounds (all four quadrants, 2 minutes each)
• Ask patient about passage of gas (flatus)
• Advance diet only after confirmed peristalsis (clear liquids → soft → regular)

Failure of bowel function to return may indicate mechanical obstruction, which requires surgical intervention — a critical distinction for Charge/Head Nurses.

1. Cash banked from sales = Closing Bank ($6,320) + Cheques issued ($19,950) - Opening Bank ($4,240) - Sale of Asset ($3,000) = $19,030.
2. Total Sales = Banked Sales ($19,030) + Cash Drawings ($5,400) + Cash Wages ($7,200) + (Closing Cash $271 - Opening Cash $264) = $19,030 + $5,400 + $7,200 + $7 = $31,637.
