Answers

Which one of the following statements does not accurately describe vibrations?
A: Forced vibrations, such as those between a tuning fork and a large cabinet surface, result in a much lower sound than was produced by the original vibrating body.
The answer is A
8) is b.

im not sure if this is right though

18) is d

Which one of the following statements does not accurately describe vibrations?

A. Two bodies with the same vibration frequency that are placed next to each other will exhibit sympathetic vibrations as one body causes the other to vibrate.

B. Resonance occurs as a result of sympathetic vibrations.

C. Forced vibrations, such as those between a tuning fork and a large cabinet surface, result in a much lower sound than was produced by the original vibrating body.

D. A non-vibrating object can begin to vibrate as a result of forced vibrations.

THE CORRECT ANSWER FOR THIS QUESTION IS C

Which one of the following statements does not accurately describe vibrations?

A. Two bodies with the same vibration frequency that are placed next to each other will exhibit sympathetic vibrations as one body causes the other to vibrate.

B. Resonance occurs as a result of sympathetic vibrations.

C. Forced vibrations, such as those between a tuning fork and a large cabinet surface, result in a much lower sound than was produced by the original vibrating body.

D. A non-vibrating object can begin to vibrate as a result of forced vibrations.


THE ANSWER IS C I GOT IT 100% CORRECT ON MY EXAM.

5-B

8-B

18-C

Explanation:

Hello! Let's solve this!

The answers are

5- B- Forced vibrations, such as those that occur between a fretboard and a large cabinet surface, produce a much lower sound than that produced by the original vibrating body.

8- B. The area covered by the wavefront increases as the wave progresses, but the energy that passes through a wavefront in a unit of time decreases.

18- c- The frequency of the sound waves will change for the listener as a result of the Doppler effect.

The Doppler effect is a change in frequency due to a change in the source.

A diatonic scale is a heptatonic scale which includes five whole tones and two semitones in each octave where semitones are separated from each other by two or three whole tones.

The correct answer is option D.

The statement that does not accurately describe the diatonic scale as it corresponds to the setup on a piano keyboard is - A scale would include a series of eight notes, where the first and seventh notes have the same letter.

A

Explanation:

The diatonic scale consists of seven notes, namely C,D,E,F,G,A,B (C major scale) on a Keyboard, these notes are the white ones. The black and white ones on the keyboard scales are called Chromatic scale.

A scale besides having seven notes, it must have 5 tones intervals and 2 half tones (E-F and  C-B, for the C major scale)

As the note after B, is C. And the C major scale is completely diatonic, and also a frequency does it's not only related to C scale. The answer is A.

Correct answer choice is :


A) Resonance occurs as a result of sympathetic vibrations.


Explanation:


Resonance is an aspect in which a vibrating mode or external force makes another system to vibrate with a higher amplitude at particular wavelengths. Frequencies at which the response amplitude is a relative maximum are identified as the system's booming frequencies or vibration frequencies.

This is an example of resonance - when one object vibrating at the same natural frequency of a second object forces that second object into vibrational motion. The result of resonance is always a large vibration.

Answer D. Forced vibrations, such as those between a tuning fork and a large cabinet surface, result in a much lower sound than was produced by the original vibrating body Because this statement contridicts the above statement, it is not accurate
