Retention focuses on preventing undesirable detachments of talented and motivated workers. The goal isn't zero turnover (some turnover is healthy), but rather keeping high-value employees who contribute significantly to organizational success.

$v = \sqrt{2gh}$, so $P = mv = m\sqrt{2gh}$

New momentum: $P' = m\sqrt{2g(2h)} = \sqrt{2}\,P$

Percentage change $= (\sqrt{2}-1)\times 100 \approx 0.414 \times 100 = \mathbf{41\%}$

Hypertrophic Pyloric Stenosis (HPS) — classic presentation:

• Age: 2–8 weeks (peak at 3–6 weeks)
• Gender: Males > females (4:1 ratio)
• Projectile, non-bilious vomiting (post-pyloric, so no bile)
• Hungry after vomiting (not ill-appearing)
• Olive-shaped mass palpable in right epigastrium (hypertrophied pylorus)
• Visible peristaltic waves (left to right)

Electrolyte imbalance:

Repeated vomiting of gastric acid (HCl) causes loss of H⁺ and Cl⁻:

\[\text{Loss of HCl} \Rightarrow \downarrow \text{Cl}^- \Rightarrow \uparrow \text{HCO}_3^- \Rightarrow \text{Metabolic Alkalosis}\]

Kidney compensates by retaining H⁺ and excreting K⁺ → Hypokalemia

Result: Hypochloremic, hypokalemic metabolic alkalosis

Diagnosis: Ultrasound (pyloric muscle thickness \(\geq 4\,\text{mm}\), channel length \(\geq 16\,\text{mm}\))

Treatment: First correct electrolytes and dehydration, then Ramstedt pyloromyotomy (surgical — curative).

TQM programs are designed to improve the quality of all the processes that lead to a final product or service. In TQM, every aspect of the organization is oriented toward providing a quality product or service - it's a comprehensive quality philosophy.

In a soft ferromagnetic material placed in an external magnetic field:

• Domains whose magnetisation is aligned with the field grow in size (domain wall movement).
• Domains misaligned with the field shrink in size.
• Additionally, domain magnetisation can rotate to align with the applied field (domain rotation).

Therefore, domains may both increase or decrease in size AND change orientation. Option B is correct.
