The inclusion of interviews with community members drawing a sketch map and any other illustrative material in South Africa helps in the effectiveness of qualitative scientific research.
<h3 /><h3>What is qualitative scientific research?</h3>
It is an approach whose scope focuses on understanding societal phenomena through the study of subjective aspects such as culture, behavior, place and time. The collection of data and information is usually done in a more comprehensive way, and interviews, case studies and analysis techniques can be carried out to understand the hypotheses.
Therefore, the use of a sketch map or illustrative material may be appropriate in conducting qualitative research in South Africa, in order to reduce communication and cultural barriers that may arise and imply the effectiveness of the research.

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.
