Sample Questions and Model Answers
Sample 1: Physics Calculation
Question: A car accelerates uniformly from 20 m/s to 30 m/s over 5 seconds. What is its acceleration?
Solution:
Using the formula:
\[ a = \frac{v - u}{t} \]
where
\( v = 30\, \text{m/s} \),
\( u = 20\, \text{m/s} \),
\( t = 5\, \text{s} \).
\[ a = \frac{30 - 20}{5} = \frac{10}{5} = 2\, \text{m/s}^2 \]
Answer: The acceleration is 2 m/s².
Sample 2: Chemistry Explanation
Question: Explain why ionic compounds tend to have high melting points.
Answer: Ionic compounds consist of positively and negatively charged ions held together by strong electrostatic forces of attraction. These forces require significant energy to overcome, resulting in high melting points for ionic solids.
