When a car accelerates and moves away from a stationary spectator, the sound wave detected by the spectator experiences a shift in frequency. This occurrence is referred to as the Doppler effect.
The Doppler effect occurs when there is relative motion between the source of a wave (in this case, the car) and the observer (the stationary spectator). In the case of sound waves, if the source is moving away from the observer, the perceived frequency of the sound decreases. This means that the pitch of the sound appears lower to the spectator.
When a car's horn emits a sound wave of a consistent frequency and accelerates while moving away from a spectator, the perceived frequency of the sound wave decreases. This is because the sound waves are stretched out, or "stretched" in terms of wavelength, due to the motion of the source away from the observer.
Consequently, the sound wave detected by the spectator will have a lower frequency and hence a lower pitch compared to the original frequency of the car's horn. The change in frequency is proportional to the relative velocity between the car and the spectator.
It's worth noting that the Doppler effect also applies when the source is moving towards the observer, in which case the perceived frequency increases. However, in the scenario described, with the car moving away from the spectator, the sound wave frequency is observed to decrease.

TRUE/FALSE which of the following is not true about gregorian chant (plainchant) melodies?
"They are in Hebrew and Syrian." is NOT true of Gregorian chant (plainchant) melodies. So the option d is correct.
Latin is used to write Gregorian chant (plainchant) tunes, not Hebrew or Syrian. The melodies, which had their genesis in the Latin Church of Late Antiquity, developed throughout the Middle Ages before becoming a mainstay of European classical music in the baroque and classical periods.
Gregorian chant melodies are written in Latin, despite the fact that certain translations may exist in other languages. Nearly all of the melodies in Gregorian chant are composed in Latin, and the music is based on a Latin text. Even if there may be adaptations in other languages, the original melodies for the majority of the modern chant tunes are in Latin.

When compared to an audit performed prior to 1900, an audit today: Multiple Choice Includes a more detailed examination of all individual transactions. Is less likely to include consideration of the effectiveness of internal control. Has bank loan officers as the primary financial statement user group. Is more likely to use sampling in more areas.
Modern audits today are much more detailed than audits from prior to 1900.
The correct option is A.
Auditors today are expected to carefully examine each and every individual transaction, ensuring its accuracy and validity and also providing assurance to the stakeholders. Not only are auditors today more focused on the accuracy of individual transactions but they are also expected to assess the effectiveness of internal controls.
Moreover, the primary financial statement user group is no longer just loan officers; nowadays, it typically includes investors, creditors, and analysts, who use the financial information to assess the financial health of the company.
Finally, modern audits are more likely to use sampling in more areas due to advances in technology and more complex financial approaches. Sampling enables auditors to evaluate compliance with laws and regulations in order to detect potential fraud, thereby providing more thorough auditing process for stakeholders.
