They should study about how volcanoes erupt or explodes
Answer:The phase of moon when between new moon and half moon is crescent and more than half and less than full is gibbous. Thus, during waxing gibbous and waning gibbous, the phase of the moon would be more than half of moon's surface.
Explanation:Waxing gibbous

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.
Yes they can, using both seismographes they find the epicenter of the earthquake.
