What is the average orbital speed of Earth around the Sun? (Note: r = 1.5 × 10¹¹ m and P = 3.16 × 10⁷ s.) A) about 30 km/s B) about 4.7 km/s C) about 9.8 m/s² D) 365 days E) 1,000 km/s

Question

Quizplus · Accepted Answer

The average orbital speed of Earth can be calculated using the formula v = 2πr/P. Substituting the given values, v = 2π(1.5 × 10^11 m) / (3.16 × 10^7 s) ≈ 29.8 km/s, which is approximately 30 km/s.
