Answer:
Average speed = 6 km/h and Average velocity = 0.67 km/h
Explanation:
Given that,
A dog walks 10 km north in 2 hours and then 8 km south in 1 hour.
(a) Average speed = total distance traveled divided by total time taken
Distance = 10+8 = 18 km
Total time = 2+1 = 3 h
Average speed = (18/3 )km/h= 6 km/h
(b) Average velocity = net displacement divided by total time taken
Let north is positive and south is negative
Displacement = 10+(-8) = 2 km
Total time = 2+1 = 3 h
Average velocity= (2/3 )km/h= 0.67 km/h

<h2>Answer:</h2>
<u>Screen recorder</u><u> is the least recommended one</u>
<h2>Explanation:</h2>
There are three types of recorders. They are Smart Recorder, Web Recorder and Screen or sometimes called Standard Recorder. Smart Recorder is used for desktop applications while Web recorder is used for Web-based applications. The least recommended one is Screen Recorder which is used for building simple tasks that involves few mouse clicks and keystrokes. It works by capturing screen co-ordinates and therefore, no calibration is taken into account. It is generally used when you plan to run the task on the same machine on which, it was recorded.
