Answer:
Statement that is true about electromagnetic and mechanical waves is:
Option B: Mechanical waves must travel through a medium, but electromagnetic waves do not require a medium to travel.
Explanation:
'Electromagnetic' waves do not need any medium to travel whereas 'mechanical waves' need a medium or matter for transmission. Electromagnetic waves are produced by the 'vibrations' of the charged particles. They can even travel in vacuum.
On the contrary, mechanical waves are caused by the 'wave amplitude'. Mechanical wave can travel in solid, liquid and gas and are considered to be periodic disturbance.
Thus, Option B is the most statement apt explaining the difference between electromagnetic and mechanical waves.
They have checks and balances to keep each other in check.
According to the study of the anthropologist David, it can be inferred that US military bases and military actions are ineffective ways of solving international problems (option A)
Since its formation, the United States has been a very influential country worldwide. Today it is one of the world's economic powers and its influence on other countries transcends all kinds of issues.
After World War II, the United States and the Soviet Union shared the label of being world powers. This unleashed competition in all aspects to prevail globally over its rival. Due to the above, the US intervention in other countries intensified as in the case of:
- Vietnam
- South Korea
- Europe
- South America
- Middle East
These interventions have been aimed at solving different problems in the countries. However, the result has been adverse because this only intensifies the problem of violence, violating the self-determination of the people.
According to the above, the most correct conclusion reached by the anthropologist David is that the intervention of the United States has not contributed significantly to the improvement of the problems in other countries.
Note: This question is incomplete because the options are missing. Here are the options:
- A. U.S. military bases and military actions are ineffective ways of solving international problems.
- B. U.S. military bases are effective in benefiting indigenous peoples.
- C. U.S. military bases are effective in benefiting U.S. citizens.
- D. U.S. military bases create more jobs for U.S. citizens than would funding education and health-care industries within the United States.
