Trait theory

Explanation:

The answer is the trait theory. This theory studies peoples personalities. Trait theory has the belief that people have different characteristics or ways of behaving. Gordon allport was among the first persons involved in the study of traits.

Gordon identified traits as cardinal, central and secondary trait

Through factor analysis, Raymond cartel generated 16 character traits

Eysneck based his personality theory on introversion against extroversion, neuroticism against stability, psychoticism against stability.

People can fall into any of these at any time and it determines how they behave at that certain point.

Explanation:

Answer:

During a chemical reaction, Bromine (Br) would be expected to  gain 1 valence electron to have a full octet.

Explanation:

In the periodic table the elements are ordered so that those with similar chemical properties are located close to each other.

The elements are arranged in horizontal rows, called periods, which coincide with the last electronic layer of the element. That is, an element with five electronic shells will be in the fifth period.

The columns of the table are called groups. The elements that make up each group coincide in their electronic configuration of valence electrons, that is, they have the same number of electrons in their last.

The elements tend to resemble the closest noble gases in terms of their electronic configuration of the last layer, that is, having eight electrons in the last layer to be stable.

Bromine belongs to group 17 (VII A), which indicates that it has 7 electrons in its last shell. So bromine requires more energy to lose all 7 electrons and generate stability, than it does to gain 1 electron and fill in 8 electrons to be stable. So:

During a chemical reaction, Bromine (Br) would be expected to  gain 1 valence electron to have a full octet.

Explanation:

M/S formula

The weight would take 4.95 seconds to fall 120 m down the cliff if it was thrown downwards at 1.25m/s

The equations of motion can be described as that those equation which established a relationship between the acceleration, velocity, time, and displacement of a moving b.ody

The mathematical form for the representation of the equations of motions:

[tex]v = u +at\\S = ut +(1/)2at^2\\v^2-u^2 = 2aS[/tex]

Given, the velocity with a weight with which it threw = 1.25 m/s

The distance covered by the weight of reaching the surface, S = 120 m

From the 2nd equation of motion, calculate the time that the weight will take to reach the surface:

S = u.t + (1/2) gt²

120 = 0 + (1/2) × 9.8 × t²

t = 4.95 s

Therefore, the weight will take 4.95 s to fall 120m down the cliff if it was thrown downwards at 1.25 m/s.

All of the given options are true to some extent, but option B, "by taking a closer look at the natural world," is the least accurate in describing how scientists use creativity.

The scientific invention refers to the process of creating or developing new devices, technologies, or methods that are based on scientific principles and aimed at solving practical problems or improving the quality of life.

The invention is a crucial part of scientific progress, as it allows scientists to apply their knowledge and discoveries to real-world problems and challenges. Scientific inventions can range from simple gadgets to complex machines, and they can have a significant impact on society and the economy.

The process of scientific invention often involves a combination of creativity, knowledge, and experimentation. Inventors use their creativity to come up with new ideas and then use their scientific knowledge to design and develop prototypes. They then test and refine their inventions through experimentation, making modifications and adjustments until they achieve the desired results.

Examples of scientific inventions include the telephone, the automobile, the airplane, the computer, and the Internet, among many others. These inventions have transformed society and the way people live, work, and communicate, and they continue to inspire new ideas and innovations today.

Here in the Question,

Option A. By requiring evidence and thinking logically: Scientists use creativity to generate hypotheses and design experiments, but they also rely heavily on evidence and logical thinking to test and refine their ideas. They use creativity to develop new methods and technologies for data collection and analysis, but they also demand rigorous testing and replication to confirm their findings.

Option B. By taking a closer look at the natural world: While observation is an essential part of scientific inquiry, it does not necessarily require creativity. Many scientific discoveries have been made by careful observation and recording of natural phenomena without the need for creative thinking. However, scientists may use creativity to design experiments that allow them to observe and measure previously unobservable or hard-to-measure phenomena.

Option C. By asking questions about the natural world: This is a crucial aspect of scientific inquiry and involves using creativity to generate new and interesting questions that have not been explored before. Scientists use their creativity to come up with novel ways of approaching complex problems and to identify potential solutions that may not be immediately obvious.

Option D. By using prior knowledge to solve problems: Scientists build on existing knowledge and use their creativity to develop new theories and models that can explain and predict natural phenomena. They use creativity to develop new experimental techniques and methods for data analysis that allow them to push the boundaries of what is currently known.

However, option B, "by looking more closely at the natural world," is the least accurate in describing how scientists use creativity. All of the other options are true to some extent.

Explanation:

Plasma can conduct electricity because plasma consists of electrically charged particles called ions, instead of uncharged particles such as atoms or molecules.

Explanation:

The given number is 1.30x10-5. We need to convert it into scientific notation. We know that, any no can be written in this form as follows :

[tex]N=m. 0\times 10^n[/tex] ...(1)

m is any real no and n is any integer

If we compare the given no with equation (1), then, we found that m = 1.3 and n = -5.

It means that the given no is already in scientific notation. It can be written as :

[tex]N=1.30\times 10^{-5}[/tex]

The scientific notation for 1.30 × 10⁻⁵ is  1.30E-5.

Scientific notation is a way to represent numbers that are either very large or very small using powers of 10. It consists of two components: the coefficient and the exponent.

In the given number, 1.30 × 10⁻⁵, the coefficient is 1.30, and the exponent is -5. The coefficient represents the significant digits of the number, and the exponent indicates the power of 10 by which the coefficient should be multiplied.

To convert the number to scientific notation, you start by moving the decimal point to the left until there is only one non-zero digit to the left of the decimal point. In this case, the decimal point is moved 5 places to the left, resulting in the coefficient 0.000013.

The exponent, -5, tells us that the decimal point has been moved 5 places to the left. In scientific notation, a negative exponent indicates a small number, as in this case.

Putting it all together, the scientific notation for 1.30 × 10⁻⁵ is 1.30E-5, where the "E" represents "times ten to the power of." It means that the number is 1.30 multiplied by 10 raised to the power of -5, which is equivalent to 0.000013 in standard decimal notation.

Therefore, 1.30E-5 is the correct scientific notation.
