Answers

Answer 1

Answer:

1. True.

2. True.

3. True.

4. False.

5. True.

Explanation:

Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.

Sound are mechanical waves that are highly dependent on matter for their propagation and transmission.

Sound travels faster through solids than it does through either liquids or gases.

1. True: Light can be reflected if it is directed towards a mirror. A mirror that is typically made of ordinary glass and has a flat reflecting surface.

Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.

Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface such as a plane mirror.

2. True: The speed of light remains the same even if it travels from one material to another. The speed of light is 3 * 10⁸ meters per seconds and it's a constant regardless of medium of propagation.

3. True: Sound could be either soft or loud.

A soft sound typically has a low volume while a loud sound posseses a high volume. An example of a soft sound is the sound from a piano while an example of a loud sound is a train's horn.

4. False: The loudness of sound decreases as it moves nearer the observer.

The loudness of a sound is directly proportional to the square of the amplitude of the sound and as such the loudness of sound increases as it moves nearer the observer.

5. True: Echo is the term used for the sound that is reflected back to its source.

Answers

Answer:

Whig party Free Soil party

Explanation:

The Whig party was the main precursor to the Republican party. They were very influential in the U.S. before the Civil War and if not for sectional divisions, would have contributed a slew of Presidents. The Whig party wasn't a big opponent of slavery but the Northern Whigs felt strongly enough against it to switch to the Republican party in the decade before the Civil War.

There was also the Free Soil party. This party was dedicated to ensuring that slavery would not spread to the new territories that the U.S. had acquired. They found it beneficial to join the Republican party which was anti-slavery.

Answers

Answer: perfectly consistent with Madison's proposed national veto over objectionable state laws

Explanation:

James Madison believed that the Federal Government through Congress, should have the right to veto objectionable state laws so that states would not get away with doing whatever they want in areas the Constitution was lacking.

The action by the 1965 Voting Rights Act described above is in line with this veto suggestion because it was passed mainly with the Southern States as these states had been limiting the rights of Black people to vote through some state legislature and intimidation. Justice officers being allowed to go into communities to register voters was to counteract this.

Enlightenment-era political philosophers such as Hobbes, Locke, Rousseau, and Montesquieu

2. adhered to traditional social customs in the creation of governmental offices,
3. emphasized governmental structures based on reason and social progress.

Was it possible for the US to definitively win the Vietnam war?

Answers

Answer:

When talking about the Vietnam War, it is necessary to make a distinction between the military results and the social impact of the conflict. Thus, in 1973, when the Vietnam War came to an end with an American defeat, things were going relatively well for the United States in the military field. In other words, several victories had been obtained in specific battles, although the guerrilla war continued to cause several headaches for the American soldiers. Therefore, the war was ended rather by antiwar social pressure that saw the conflict as a meaningless conflict in which America had no genuine interest and in which the lives of young Americans had no reason to be risked. Therefore, if it had not given in to social pressure, most likely America would have ended up winning the war.
