1- The correct answer is A. For resonance to occur, the object must experience a frequency equal to its natural frequency.

The resonance is a phenomenon that occurs when a body capable of vibrating is subjected to the action of a periodic force, whose vibration period approaches the characteristic period of vibration of said body.

2- The correct answer is A. When tightening a string on a guitar, its natural frequency increases.

3- The correct answer is D. Resonance in air columns is used in trumpets.

A trumpet exhibits natural resonance frequencies, which follow a harmonic sequence, quite close to the tenth harmonic.

4- The correct answer is D. The term that describes the number of crests that pass a point in a given amount of time is frequency.

Frequency is a quantity that measures the number of repetitions per unit of time of any phenomenon or periodic event.

5- The correct answer is C. A human could detect a sound frequency of 50 hertz, as the human ear has a limited range of perception, which very roughly (since it varies in each individual and with age for only one) ranges from 20 Hz to 20,000 Hz.

The correct answer is <span>post-conventional moral reasoning.

</span>According to Kohlberg's theory of moral development, post-conventional moral reasoning is the highest level of moral development a person can achieve in their lifespan. This type of moral reasoning is based on autonomous judgments based one one's own personal morals and value systems. While people with post-conventional moral reasoning understand and agree with society's laws and values to an extent, they are aware that they are not always the best option depending on the situation at hand.
