  1. Question 1

    Q1. The range of a 100-meter-high TV transmitter aerial is about:

    • A) 10 km
    • B) 20 km
    • C) 36 km
    • D) 50 km

    Answer: 36 km

    Explanation: The line-of-sight range formula for a transmitter is d ≈ 3.57√h km; for h = 100 m, d = 3.57 × √100 = 3.57 × 10 ≈ 35.7 km, approximately 36 km.
