What is meant by the following terms: a) beat; b) subdivision; c) meter; d) accents; e) syncopation; and f) tempo

suter [353]

Answer:

(a) Beat: A beat defines the movement and speed of a rhythm. It describes the flow of the rhythm of a piece of music. There are various concepts related to beat such as tempo, groove and meter.

(b) Subdivision: Subdivision typically means dividing a large entity into smaller entities. In music, rhythms can be broken down into sub-sequences. For example, starting with a whole note, the note can be divided into quarter notes which can further be subdivided into eight notes and so on.

(c) Meter: A meter describes the structure of a beat. It is sometimes represented as the time signature of a song. It defines how many individual beats there would if one were clapping their hands to the beat of a song.

(d) Accents: Accents refer to the stress or emphasis laid on a chord or musical note. They are a large measuring factor in the articulation of a musical piece.

(e) Syncopation: In music, syncopation describes an element of surprise. It occurs when rhythmic patterns fall on weak beats (or weak parts of the beat) rather than on strong beats. These kind of rhythms are usually easy to sing but difficult to transcribe.

(f) Tempo: The tempo of a beat in music is typically the speed of the beat - how fast the beats are being played or sung. It is often measured in beats per minute (BPM). This means that tempo is the number of beats played per minute.

Humans experience the longest visible electromagnetic waves as

Margarita [4]

Answer:

Red light

Explanation:

The electromagnetic spectrum classifies all the electromagnetic waves according to their wavelength/frequency. In order from shortest to longest wavelength, we have

Gamma rays

X rays

Ultraviolet

Visible light

Infrared

Microwaves

Radio waves

All of these waves are invisible to human eye, except for the "visible light" part of the spectrum. Waves in the visible light part are perceived by human as different colors, depending on their wavelength. More specifically, they appear as follows:

Violet (380-450 nm)

Blue (450-495 nm)

Green (495-570 nm)

Yellow (570-590 nm)

Orange (590-620 nm)

Red (620-750 nm)

So we see that the longest electromagnetic wave in the visible light part of the spectrum corresponds to red light.

Near the end of a marathon race, the first two runners are separated by a distance of 45.0 m. The front runner has a velocity of

xxMikexx [17]

Answer:

a. 0.7 m/s

b. The second runner

c. 4.20 meters

Explanation:

a. To know the relative speed we can use the following equation:

Relative Speed (Vr) = V1 - V2

The relative speed is used to compared the velocity of one object (V1) to another object (V2). To learn the Relative Velocity from the second runner to the first we do the following:

Relative Speed (Vr) = Second Runner Velocity (Vs) - First Runner Velocity (Vf)

Vr = 4.20 m/s - 3.50 m/s

Vr = 0.7 m/s

This means that the second runner is gaining 0.7 meter from the first runner each second.

b. To know which runner will gain the race, we need to keep in mind, that the seconds runner is 45 meter more away that the first runner from the goal. Knowing this, the winner will be the one that reach the goal on less time.

Because movement is constant, we can use the following equation:

Velocity (V) = Distance (D) / Time (T)

To get the time we do:

T = D / V

Now, for the first runner:

T = 250 meters / (3.50 m/s)

T = 71.42 seconds

For the second runner.

T = (250 meters + 45 meters) / (4.20 m/s)

T = 70,23 seconds

Because the second runner takes less time to reach the goal, he wins the race.

c. Because it is know how much time takes the winner to get to the finish line, we can use that same time to know how far was the first runner from the goal. This is posible we know that how far he is from the goal is as follows.

Distance from goal (Dg) = Total Distance (D) - Distance travelled (Dt)

Where Total Distance (D) is 250 mts. And the distance travelled can be obtained by using the following equation.

Velocity (V) = Distance (D) / Time (T)

Searching for distance:

D = V / T.

D = (3.50 m/s) * 70.23 s

D = 245,80 meters

Soo

Distance from goal (Dg) = Total Distance (D) - Distance travelled (Dt)

Dg = 250 meters - 245,80 meters

Dg = 4,20 meters

The first runner was 4,20 meter behind the second one when the second runner crossed the goal
