Answer:

It is the part of the ocean where new crusts are formed.

The place marked with A on the map is the place in the ocean where the new crust is formed. That is a place where there's a divergent plate boundary, or rather a place where the tectonic plates are moving away from one another. The gap and cracks left between them are easy target for the magma from the mantle to penetrate towards the surface. As the magma reaches the ocean floor it starts to cool off very quickly, creating new crust, and slowly making a very large underwater mountain range known as mid-ocean ridge.

Voyager I is now about 110 AU from Earth, continuing to record its environment as it approaches the limits of our Solar System.
Monica [59]

Answer:

Answered

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.
