Analyzing the 2014 Exam Questions

To excel in physical sciences exams, it’s essential to understand the types of questions posed and the strategies to approach them. Below, we analyze some typical questions from the 2014 exemplar and discuss effective solutions.

Sample Physics Question

Question: A car accelerates uniformly from 10 m/s to 30 m/s over 5 seconds. Calculate its acceleration and the distance traveled during this period.

Solution Approach:

• Use the formula for acceleration: \(a = \frac{v - u}{t}\)
• Calculate distance using \(s = ut + \frac{1}{2}at^2\)

Calculation:

• \(a = \frac{30 - 10}{5} = 4\, \text{m/s}^2\)
• \(s = 10 \times 5 + \frac{1}{2} \times 4 \times 25 = 50 + 50 = 100\, \text{m}\)

Tip: Always identify what is asked, choose appropriate formulas, and double-check units.

Sample Chemistry Question

Question: Balance the chemical equation: \(\mathrm{C_2H_6 + O_2 \rightarrow CO_2 + H_2O}\)

Solution Approach:

• Balance carbon atoms: 2 C on both sides (already balanced)
• Balance hydrogen atoms: 6 H in \(\mathrm{C_2H_6}\), so 3 H2O molecules
• Balance oxygen atoms: 2 O in \(\mathrm{O_2}\) and in products

Balanced Equation:

\(\mathrm{C_2H_6 + 3 O_2 \rightarrow 2 CO_2 + 3 H_2O}\)

Tip: Balance atoms systematically, starting with the most complex element.
