<u>Answer:
</u>
Anti-federalists feared that the new Constitution would create a government that could be as tyrannical as the British had been is a TRUE statement.
Explanation:
- In the view of anti-federalists, the system of federalism was in itself a breach of the idea of liberty of the states as they believed that the central government would govern the functioning of the states all the time.
- They proposed that it was necessary to not allow the system of federalism to come into effect because, as they stated, it would destroy the autonomy of the states and make them powerless subjects of the federal government.
Answer:
Doppler Effect
Explanation:
Doppler Effect is a term in Physics that describes the phenomenon experienced when there is change in wave frequency during the relative motion between a wave source and its observer.
In other words, it is referred to as increase or decrease in the level of sound, or other waves as the distance between source and observer is closer or farther from each other, such that it causes change in pitch, which is noticeable by the observer.
For example, when a sound object moves towards an individual or observer, the frequency of the sound waves increases, leading to a higher pitch, and at the same time, when the sound object moves away from an individual or observer, the frequency of the sound waves decreases, leading to a lower pitch. E.g passing siren from ambulance.
Hence, in this case, the right answer is DOPPLER EFFECT
1 is false, waves can't propagate in a vacuum.
