Physics QUESTION #1039

Question 10

Two cities X and Y connected by buses every T min. A girl on scooter at 60 km/h sees buses every 30 min in her direction and every 10 min opposite. Period T and bus speed:

10 min, 90 km/h
15 min, 120 km/h✔️
9 min, 40 km/h
25 min, 100 km/h

Correct Answer Logic:

Let bus speed $=v$, period $=T$. Relative speed with girl (same direction): $v-60$. Buses come every 30 min: $\frac{vT}{v-60}=30$. Opposite direction: $\frac{vT}{v+60}=10$. Dividing: $\frac{v+60}{v-60}=3\Rightarrow v+60=3v-180\Rightarrow v=120\ \text{km/h}$. Then $T=\frac{10(120+60)}{120}=15\ \text{min}$.

Dairy Food Science and Technology QUESTION #5971

Question 17

Why is it critical to maintain the cold chain for milk below $4^{\circ}\text{C}$ throughout distribution?

To prevent lactose crystallization
To inhibit growth of psychrotrophic bacteria (e.g. $Pseudomonas\;fluorescens$, $Listeria\;monocytogenes$) that grow efficiently at refrigeration temperatures ($0\text{–}7^{\circ}\text{C}$)✔️
To prevent vitamin D degradation
To maintain homogenization stability

Correct Answer Logic:

Psychrotrophic bacteria (cold-tolerant, growing at $0\text{–}7^{\circ}\text{C}$) are the primary spoilage concern for refrigerated milk. $Pseudomonas$ spp. produce heat-stable proteases and lipases that survive pasteurization causing bitterness, rancidity, and gelation in UHT milk. $Listeria\;monocytogenes$ is a cold-tolerant pathogen.

In Imogene King's Theory of Goal Attainment, which three interacting systems form the conceptual framework?

Individual, Family, Community
Personal, Interpersonal, Social✔️
Biological, Psychological, Sociological
Micro, Meso, Macro

Correct Answer Logic:

Correct Answer: B

King's Conceptual System (1981) consists of three open, dynamic interacting systems:

Personal System: The individual — includes concepts of body image, growth, development, perception, self, space, and time
Interpersonal System: Two or more individuals interacting — includes communication, interaction, role, stress, and transaction
Social System: Larger groups — includes authority, decision-making, organization, power, and status

King's Theory of Goal Attainment (a middle-range theory derived from the framework) focuses on the nurse-patient transaction within the interpersonal system. The transaction leads to goal attainment, which represents health.

Key equation: Perception → Judgment → Action → Reaction → Interaction → Transaction → Goal Attainment
