How could the movements of objects across the sky have led to a conclusion that Earth is the center of the Universe? I will award brainliest to person it’s best answer. Must be correct. If wrong: Reported answer

Answers

Answer 1

The movements of objects across the sky could have led to a conclusion that Earth is the center of the Universe through the geocentric model, which was widely accepted in ancient times. This model proposed that the Earth is stationary and located at the center of the Universe, with all other celestial bodies, including the Sun, Moon, and planets, orbiting around it.Observations of the sky, including the apparent movements of the Sun, Moon, and planets, were consistent with this model, as they appeared to move in circular paths around the Earth. However, as astronomers made more precise observations and measurements, they began to notice that the geocentric model had limitations and inaccuracies.Eventually, the heliocentric model, which proposed that the Sun was at the center of the Solar System, replaced the geocentric model. This was based on the observations of Copernicus, Galileo, and other astronomers who discovered evidence that the Earth and other planets revolved around the Sun, not the other way around.

Dr. Bartos is a psychologist who believes that pet therapy leads to less anxiety. She hopes to fund a research project to demonstrate this so she can promote animal adoption at the local shelter where she volunteers. She is proposing an experimental study to examine this belief

Answers

To conduct an experimental study, Dr. Bartos would need to:

Recruit participants who experience anxiety.
Randomly assign participants to one of two groups: a treatment group that receives pet therapy or a control group that does not receive pet therapy.
Measure the anxiety levels of both groups before and after the study using a standardized anxiety questionnaire.
Analyze the data to determine if there is a statistically significant difference in anxiety levels between the treatment group and the control group.
Interpret the findings and draw conclusions about the effectiveness of pet therapy in reducing anxiety.
If the study results show that pet therapy significantly reduces anxiety levels in the treatment group, Dr. Bartos can use these findings to promote animal adoption and the use of pet therapy as a treatment for anxiety.

Does Health Law and its provisions in changing people's view of women?

Answers

Although it is not always a direct or immediate consequence, health law and its provisions may affect how people regard women. These discussions may in turn affect how people see women's autonomy.

The provision of healthcare services and the preservation of the public's health are governed by a collection of legal concepts, rules, and policies known as health law. Health legislation aims to safeguard patients' rights and privacy while ensuring access to high-quality healthcare services. Medical liability, healthcare funding and insurance, patient safety, and public health emergencies are only a few of the many topics covered by health law. It also includes regulations covering particular facets of healthcare, such as reproductive, psychiatric, and elder care. Health legislation is continually changing to handle new problems and challenges in the healthcare sector. It is essential in determining how healthcare is delivered and how policies are made.

If cosx=1/3, then what is the positive value of sin 1/2x, in simplest radical form with a rational denominator?

Answers

To solve this problem, we can use the identity sin(2x) = 2sin(x)cos(x).

First, we need to find the value of sin(x), which we can do using the Pythagorean identity:

sin^2(x) + cos^2 (x) = 1

Since cos x = 1/3, we have:

sin^2 (x) + (1/3)^2 = 1
sin^2 (x) = 8/9
sin x = sqrt(8)/3 * sqrt(9)/sqrt(9)
= +/- (2/3)sqrt(2)

We take only positive radical since sine is positive in first and second quadrants.

Now that we know sin x, let's find sin((1/2)x):

Using the half-angle formula for sine:
(sin((1/2)x))^±²= [1-cos(x)] / ²

we get:
(sin((½)x))^±²= [¹-³]/₂=[⁴]/₆≡[+/-]√[4]/√6 ≡ [+/−][ √4 ]/[ √6 ]

Therefore,
the positive value of sin ((½)x):

[sin ((½)x)]° ≡ (+)[ √4 ]/[ √6 ]
° ≡ (∛96)/(3∛{})
≈ ..

Hence, the answer is approximately equal to ±0.177.
