There attitudes and viral language and war
Answer:
Outreach
Explanation:
The three options provided are types of people i.e "children", "elderly", and "homeless". So, the fourth element too should be a type of people. Hence, "Finances", and "Conservation" are eliminated.
Out of "Students" and "Outreach", "outreach" would be better option;
Firstly because, children (age), elderly (age) homeless (location), and then fourth too should be about location i.e. "Outreach"
Secondly, because "students" is a sort of occupation, children may also be students. So, "Students" does not fit well with the three provided options.
The objects that produce large amplitude waves are Stars, Large machines, Rocks falling from the mountain, Earthquakes, Volcanoes
The objects producing small amplitude waves include ping-pong ball, Tuning fork, stones, Speakers, Spring
<u>Explanation</u>:
The wave's amplitude is characterised by the ultimate displacement of an object from its median position. Generally, wave with high energy (or the waves emanating from big bodies or high energy bodies) are high amplitude waves. Since the body has a high amount of energy, it produces a comparatively large amount of displacement of the particle. hence the high amplitude.
Similarly, small bodies or bodies with less energy produces a low amplitude wave. This also can be understood in terms of displacement of the particle from its mean position.
