Answer:
269,000
Explanation:
The distance between Proxima Centauri and the Sun, d₁₁ = 4.246 light years
The distance between Earth and the Sun, d₂ = 1.58 × 10⁻⁵ light years
The ratio of the distances are;
d₁/d₂ = 4.246/(1.58 × 10⁻⁵) = 268734.177215 ≈ 269,000 times
Therefore, Proxima Centauri is approximately 269,000 times further from the Sun than the Earth is from the Sun
The metal’s feely moving sea of electrons
Answer: 157 m
Explanation:
30 s = ½ min, so 100 / 2 = 50 revolutions
d = rθ = 0.50(50(2π)) = 50π m = 157 m
30 km in one hour I believe , because thirty •2= 1 hour
15•2= 30 km
