Answer:
Bonjour,
QUESTION)
AU is the astronomical unit referring to the distance between the Earth and the Sun 1 AU is equal to 1,50 × 10¹¹ m.
It therefore comes,
[tex]\Delta t = \frac{d}{v} = \frac{9,5 \times 1,5 \times 10^{11}}{3,0 \times 10^8} = 4 750 \Longleftrightarrow \Delta t \approx 80 \text{ m}[/tex]
