Pender's Health Promotion Model (HPM, 1982; revised 1996) is grounded in social cognitive theory and emphasizes positive health behaviors rather than disease avoidance.
Key components of the HPM:
- Individual Characteristics and Experiences: Prior behavior, personal factors (biological, psychological, sociocultural)
- Behavior-Specific Cognitions and Affect: Perceived benefits, perceived barriers, perceived self-efficacy, activity-related affect, interpersonal and situational influences
- Behavioral Outcome: Commitment to a plan of action → Health-promoting behavior
Creativity is specifically defined as the thinking process involved in producing ideas or concepts that are new, original, and useful. While innovation involves implementing creative ideas, and intelligence involves applying knowledge, creativity is the term for the generative cognitive process itself.
Correct Answer: A — Creativity.
\(\lambda = \dfrac{3 \times 10^{17} \text{ nm s}^{-1}}{6 \times 10^{15} \text{ s}^{-1}} = 50\) nm
This wavelength (50 nm) lies in the extreme UV (EUV) region. Note: \(c = 3\times10^8\) m/s \(= 3\times10^{17}\) nm/s.
- $2$ moles of resin ($2 \times 206\text{ g}$) react with $1$ mole of $Ca^{2+}$.
- Total mass of resin = $412\text{ g}$.
- Uptake per gram = $\frac{1\text{ mole } Ca^{2+}}{412\text{ g resin}}$.
A stone falls freely from rest. The distance covered in the last second of motion equals the distance covered in the first 3 seconds. How long does the stone take to reach the ground?
Distance in first 3 s: $s_3 = \dfrac{1}{2}(10)(3)^2 = 45\text{ m}$
Distance in last 1 s of total time $T$ (using $s_n = u + \dfrac{a}{2}(2n-1)$ with $u=0$):
$s_{\text{last}} = \dfrac{g}{2}(2T-1) = 5(2T-1)$
Setting equal: $5(2T-1) = 45 \Rightarrow 2T-1 = 9 \Rightarrow T = \mathbf{5\text{ s}}$
A class has 5 girls and 7 boys. Teams of 2 girls and 3 boys are to be formed. However, two specific boys A and B cannot both be on the same team. How many valid teams can be formed?
Total teams (no restriction): $\binom{5}{2}\binom{7}{3} = 10 \times 35 = 350$
Teams where both A and B are included: Choose remaining 1 boy from 5 others: $\binom{5}{2}\binom{5}{1} = 10 \times 5 = 50$
Valid teams $= 350 - 50 = \mathbf{300}$
Dehydrohalogenation of an alkyl halide is typically carried out with:
Alcoholic KOH (strong base in ethanol) promotes E2 elimination to form alkenes. Aqueous KOH favors substitution; conc. H₂SO₄ can cause elimination but also other reactions; Zn dust is for dehalogenation (vicinal dihalides).
A business owner purchased a delivery vehicle and made these payments:
| Item | Amount ($) |
|---|---|
| Delivery vehicle purchase price | 28,000 |
| Fitting shelves inside the vehicle | 3,000 |
| Painting business logo on the vehicle | 2,000 |
What was the total capital expenditure?
Option C ($31,000) is correct.
Capital expenditure includes costs that bring a non-current asset into use or improve its capacity:
- Vehicle purchase price: $28,000
- Fitting shelves (improves functionality): $3,000
Total CapEx = $31,000
Painting the logo ($2,000) is revenue expenditure — a marketing cost that does not add to the asset's useful life.
