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:
Due to gravity and volatile matter.
Explanation:
- As the rocky matter is refractory as it forms in the relatively high and warm and the presence of the gravity also plays a crucial role in the formation of the rocky masses.
- The volatile matter solidifies at a cold temperature and such as those in the outer parts of the nebula and thus gas giant is cold and icy plants as they form away from the sun and have distinct gravitational compositions.
The space shuttle is a space transportation system, the term denoting the shuttles developed and operated by the U.S. National Aeronautics and Space Administration (NASA). It carried astronauts and cargo to and from Earth orbit.
The following are experienced by a space shuttle in orbit:
- gravity
- inertia
- centripetal force
