Answer:
It will take 3.7 seconds for the football to travel 50 meters.
Explanation:
Since the football is traveling at 13.5 meters per second, we need to divide the distance needed to travel by how fast it is moving,
50/13.5 = 3.7 seconds

How does a scientist use creativity? by requiring evidence and thinking logically by taking a closer look at the natural world by asking questions about the natural world by using prior knowledge to solve problems
Answer:
By using prior knowledge to solve problems.
Explanation:
just took the test
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.
What is a scientific invention?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.

Which theory dates back to Hippocrates and consists of a five-factor model of personality developed by Gordon Allport, Hans Eysenck, and Raymond Catell?
Answer:
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.

The bottom of a box has a surface area of 31.4cm2. The mass of the box is 47.1 kilograms. Acceleration due to gravity at s3a level is 9.80 m/s2. What pressure is exerted by the box where it rests ?
Answer:
The correct answer to the physics problem in pressure given above would be 1.5 N.
First, I converted the cm^2 to m^ 2 (31.4 cm^2 = .00314 m^2).
Then I computed for the force (F= mg = (47.1kg)(9.8m/s^2) = 461.58 N)
Consequently, I used the equation of pressure (P = Force/Area).
P = 461.58 N / .00314 m^2
P = 1.47 or 1.5 N

A. -0.8 m/s^2
B. 1.25 m/s^2
C. -1.25 m/s^2
D. -0.4 m/s^2
Answer:
-0.8 m/s²
Explanation:
Acceleration is the slope of a velocity vs. time graph.
a = Δv / Δt
a = (0 m/s − 12 m/s) / (15 s − 0 s)
a = -0.8 m/s²

1.30 x 10-5?
What is the scientific notation for 1.30x10-5
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.

How much time would the weight take to fall 120 m down the cliff if it was thrown downwards at 1.25 m/s?
Answer:
96 seconds
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
What is the equation of motion?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.
