✍️ Sample EMSAT Questions & Answers
1. What is the purpose of a compiler in programming?
A compiler translates an entire high-level language program into machine code before execution.
2. What is the electron configuration of sodium (Na, atomic number 11)?
Sodium has 11 electrons, filling orbitals in order: 1s² (2), 2s² (4), 2p⁶ (10), 3s¹ (11), giving the configuration 1s² 2s² 2p⁶ 3s¹.
3. What is the correct form of the imperative (فعل الأمر) from the verb 'يكتب' (he writes)?
The imperative form of يكتب is اُكتُب (write!). The imperative is formed by removing the present tense prefix and adding the appropriate hamza if needed.
4. A 2 kg object moves in a circle of radius 0.5 m at a speed of 4 m/s. What is the centripetal force acting on it?
F = mv²/r = 2 × 16 / 0.5 = 64 N — wait, that gives 64 N; recalculating: 2 × 16 / 0.5 = 64 N.
5. According to Darwin's theory of natural selection, which individuals in a population are most likely to survive and reproduce?
Natural selection favours heritable traits that increase an individual's fitness — its ability to survive and reproduce in its specific environment.
6. What is the conjugate base of H₂CO₃?
When H₂CO₃ donates a proton (H⁺), it becomes HCO₃⁻ (bicarbonate ion), its conjugate base. Conjugate base = acid − one proton.
