an object 3.0 cm tall is placed 25 cm from the front of a concave mirror with a radius of curvature of 46 cm . where is the image formed? express your answer using two significant figures

Answers

Answer 1

The image is formed at a distance of 287.5 cm from the concave mirror.

To determine the position of the image formed by the concave mirror, we can use the mirror formula:

1/f = 1/v - 1/u,

where f is the focal length of the mirror, v is the image distance, and u is the object distance.

Given that the radius of curvature (R) is 46 cm, the focal length (f) can be calculated using the formula:

f = R/2

f = 46 cm / 2

f = 23 cm

Now, substituting the values into the mirror formula, we have:

1/23 = 1/v - 1/25

To simplify the equation, we can find the common denominator:

25v = 23(25) + 23v

25v - 23v = 23(25)

2v = 575

v = 575 / 2

v = 287.5 cm

The image is formed at a distance of 287.5 cm from the concave mirror.

What do you think is the music of the Baroque era and how
does it differ from the music of previous eras?​

Answers

Answer:

Well, the Baroque period was made up of more complex music, especially compared to the classical era. In the Baroque era, there were orchestras made up of a bunch of instruments. But then in the classical era, the most famous pieces were simple piano music. Not that Ludwig Van Beethoven's music was simple, but it was easier to follow than music from the Baroque period.

I hope this helps a little bit. Try to listen to Bach, and then Beethoven, and see the difference. Bach was part of the Baroque period, and Beethoven was part of the Classical period.

Post-Impressionism refers to a movement in art that arose in France in the late 1800s. The artists associated with this movement departed from the naturalism of the Impressionists and delved further into the abstraction of form and color. Post-Impressionists developed a range of distinct styles, each with its characteristics, which are not easy to classify. Instead of attempting to depict landscapes as realistically as possible, they frequently tried to create a visual representation of the scene as they experienced it. They utilized daring color combinations and brushwork to convey their perception of the world around them.The correct statement about postimpressionist paintings is that they rejected traditional artistic techniques. The artists related to this movement sought to express their feelings and ideas in novel ways, deviating from the techniques and methods that had previously been established in art.

1. Name and describe three major elements of composition commonly found in Baroque music.

I've spent 7 hours looking for the answer but can not find it.

Please try to give me references and or answers with the cite to help me

Answers

The three major elements of composition that are commonly found in Baroque music are basso continuo, terraced dynamics, and ornamentation. Here are some details about each element: Basso continuo.

Basso continuo, also known as figured bass, was a common feature of Baroque music. It is a technique in which the bass line of the music is accompanied by an instrument that plays a chord progression. This is typically done by a keyboard instrument such as a harpsichord, organ, or lute. The chord progression is indicated by a series of numbers above or below the bass line, and the performer is expected to improvise the accompaniment based on these numbers.

Terraced dynamics: Terraced dynamics is a technique in which the volume of the music jumps suddenly from one level to another, rather than changing gradually. This creates a series of "terraces" in the sound, rather than a smooth curve. This technique is commonly used in Baroque music, and is often achieved by the use of contrasting instrumental groups, such as a group of loud brass instruments followed by a group of quiet strings.

Ornamentation: Ornamentation refers to the embellishments and decorations that are added to a piece of music, beyond the basic melody and rhythm. Ornamentation was a common feature of Baroque music, and was often used to make a simple melody more interesting. Common ornaments included trills, turns, mordents, and grace notes. In Baroque music, performers were often expected to improvise their own ornamentation, rather than playing it exactly as written.

Answers

The step that is NOT one of the required steps in Hobbes' proposed method to escape the brutal and warring state of nature is:

"All human beings must agree to revolt against the government if our life, liberty, and property are violated by the government."

In Hobbes' philosophy, he advocated for a social contract theory where individuals would voluntarily surrender their natural rights to an absolute sovereign in order to establish peace and security. The specific steps he proposed include:

All human beings must agree to seek peace.

All human beings must agree to lay down their natural right.

All human beings must agree to lay down their natural right to an absolute sovereign.

Revolt against the government, as mentioned in the second option, goes against Hobbes' concept of an absolute sovereign and is not a step in his proposed method for escaping the state of nature. Instead, Hobbes argued that individuals should submit to the authority of a sovereign to maintain order and prevent the chaotic state of nature.
