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.

Answer: inattentional blindness

Explanation:

This refers to how we tend to zoom out of everything around us and zoom in to what seems important to us at that particular moment trusting that our schemas will assist us with other things.

Since our cognitive and processing ability is limited it gives us sufficient time to focus our utmost attention to what matters more at that time.

Sometimes this happen because we don't expect certain things to happen in certain situation like standing in a checkout you are not really expecting that someone may be robbing a person just in day light.

I believe the answer is: have external ears

The seals on the other hand, only have small gap in the side of their heat but lack an external ear flap.
The function of the external ears are very similar to humans' , But sea lion's ears have different structures that help them to sustain pressure to protect them when they're diving.

Maria is an executive coach who wants to use podcasts to create a series of instructional videos and audiocasts for her clients.

Levart [38]

My suggestion to Maria is to follow these steps:

1. Choose a specific theme for each of her podcasts:

The first step should be the choice of the topic that Maria will address in the podcast. As much as Maria has knowledge of various executive coach topics and want to share everything she knows, it is interesting to focus on a certain topic in order to break it down and deliver content that really adds value to her audience.

2. Define the podcast participants:

To make her podcasts more dynamic and interesting, Maria can invite other people to participate. To attract the attention of her public, she can invite consultants, researchers or anyone else who is authoritative in the matter to share their knowledge with listeners. In that case, Maria can create podcasts in the format of interview, debate or simply didactic, so that the guest gives a class on the selected topic.

3. Plan the content that Maria will address:

Before starting to record, I recommend that Maria creates a simple script of what she is going to tackle. If out of nervousness, emotion or simple forgetfulness, Maria "hit that target" when talking, this may compromise the quality of her content.

4. Prepare herself vocally:

I remind Maria that the podcast is a digital audio file and users must clearly understand what is being said. She or her guests should have good diction and master the tone of voice so that it is not too high or too low.

5. Order the equipment to record:

Creating a podcast requires few instruments and, therefore, little financial investment. One of the only necessary tools is a good microphone, so that the audio is captured properly and transmit her message with quality for the listeners. In the market, Maria can find several options, each with different characteristics and values. It is possible to use USB microphones, flap or even her smartphone.

6. Edit each podcast carefully:

After recording the podcast, it is necessary to edit it, so that it reaches the audience with the most professional aspect possible. As much as the chosen environment is silent, it is common for some unwanted sounds to appear in the recording or unevenness of the audio. At this stage, these details must be corrected so that all the material is understandable.

7. Publish her podcasts:

After editing, her podcasts are ready to be published. For this, Maria just needs to choose the ideal platform. There are specific platforms to host audios, many of them free for both the coach and the desired listeners.

8. Disseminate her podcasts:

There are several channels that can be used for the dissemination of Maria's podcasts and she must take into account the most accessed by her audience, so that her files reach the desired target. It is possible to use social networks, her blog or video channel, along with her institutional videos so that more people have access to her channel. Place attractive messages that show the content that users will have when they listen to her podcasts. Disclosing snippets of content can also leave the listeners curious to listen to the podcast until the end.
