Explanation:
(i) 1 Astronomical Unit (A.U.) = 1.496 x 10^8 Km.
Therefore, distance of Voyager I from Earth = 71 AU = 71 x 1.496 x 10^8 = 1.062 x 10^10 Km.
(ii) The nearest star to Earth than sun is the Proxima Centauri in the Alpha Centauri system. The Proxima Centauri is 4.22 light years away from Earth.
As, 1 Light year = 63241.1 AU
The distance of the Proxima Centauri from Earth = 4.22 x 63241.1 AU = 266877.3 AU
The distance of the Voyager I from Earth = 71 AU
The number of times the distance of the Proxima Centauri from Earth is greater than that of Voyager I is = 266877.3 / 71
= 3758.835 times.
(iii) Speed of light is 1.079 x 10^9 Km/hr
Light travels 1.079 x 10^9 km in 1 hr
Therefore, 1. 062 x 10^10 Km is traveled by light in = (1.062 x 10^10) / (1.079 x 10^9) hr = 9.84 hours
That means when Voyager I was 71 AU from Earth, a observational data from Voyager I at the speed of light took 9.84 hours to reach Earth.
Answer:
Saint-Domingue (Haiti) was prosperous because of revenue earned from sugar.
Explanation:
When the Europeans came to Haiti, the native people lived in a simple way and were relatively isolated from their surroundings, let alone the world. The Europeans though thought that this place has big potential, especially in farming. What the Europeans had on mind was to create large plantations with sugar cane, thus produce sugar and make a profit out of it.
While the Europeans were not many in number, and the native population was decimated, a lot of African slaves were brought as a labor force for the plantations. The wet tropical climate enabled high-scale production of sugar cane, and with sugar becoming increasingly popular and being paid well for, the Europeans earned a lot from the trade. Haiti actually became a very prosperous island, and that was strictly down to the production of sugar cane and sugar from it.
