Read the assignment carefully and make sure you answer each part of the question or questions.
After you've written your response, go back and read it again to make sure your thoughts are clear.

Answers

Answer:

Explanation:

You can think of it as the tendency of data to cluster around a middle value. In statistics, the three most common measures of central tendency are the mean, median, and mode. Each of these measures calculates the location of the central point using a different method.

There are three main measures of central tendency: the mode(the number that occurs most often) the median ( the middle value in the list of numbers) and the mean (the average number in the list of numbers).

Answer:

The mean, median, and mode are three of the most commonly used measures of central tendency.

Explanation:

Quantitative variables are often summarized using numbers to communicate their central tendency. The numerical average; calculated as the sum of all of the data values divided by the number of values.

How Buoyancy force on an object is related to the weight of liquid it displaces?

Answers

The buoyancy force (B) is equal to the weight (W) of the fluid that a body in that fluid displaces. Fluid pressure increases with depth because of the (gravitational) weight of the fluid above. This increasing pressure applies a force on a submerged object that increases with depth. The result is buoyancy

Archimedes' principle is the statement that the buoyant force on an object is equal to the weight of the fluid displaced by the object.

Which of the following best describes the relationship between frequency and wavelength of electromagnetic waves?

A. If the frequency remains constant, the wavelength size increases.
B. As the wavelength size decreases, the frequency decreases.
C. As the frequency increases, the wavelength size decreases.
D. If the wavelength remains constant, the frequency increases.

Answers

Answer:

b makes the most sense

Explanation:

Answer:

I think C is the correct answer.

Explanation:

The higher the frequency, the shorter the wavelength. Because all light waves move through a vacuum at the same speed, the number of wave crests passing by a given point in one second depends on the wavelength.

Which of the following expresses Newton's third law?

The person with CIPA condition that is congenital insensitivity to pain with anhidrosis will not pain and temperature and decreased sweating. Here, the thermoreceptor and mechanoreceptors are affected.

What is CIPA?

CIPA is state known as congenital insensitivity to pain with anhidrosis is affecting the thermoreceptors and mechanoreceptors and thus make it unable to feel pain or temperature.

Receptors are structure able to capture signal from a stimuli and pass it to the brain from it carries a signal in return.

Mechanoreceptors are sensory receptors that transduce signals through ion channels which are mechanically gated.  These receptors reacts to touch, pressure, motion stretching etc.

Thermoreceptors realize the change in temperature in the body and external stimuli with heat. If these two kind of receptors are damaged a person will be  unable to feel pain or temperature.

Hence, a person with CIPA have affected with their  Mechanoreceptors and thermoreceptors. Thus, option B is correct.

Why do you use immersion oil with a 100X objective lens?

Answers

Answer:

For example, by placing a substance such as immersion oil with a refractive index that is equal to the glass slide in the space filled with air, more light is directed through the objective and a clearer image is observed

Explanation:

Hope you have a great day :)

The 100x lens is immersed in a drop of oil placed on the slide to eliminate any air gaps and loss of light due to refraction as light passes through glass(slide) → air → glass(objective lens)

What is Immersion oil?

Oil immersion is a technique used to increase the resolving power of a microscope by immersing both the objective lens and the specimen in a transparent oil of high refractive index, resulting in an increase in the numerical aperture of the objective lens.

An immersion oil used in microscopy essentially consists of a solution of hydrogenated terphenyl, a polybutene, and a mineral oil, which provides a solution with a refractive index between 1.5100 and 1.5240.

It is used for the highest power objectives because light refraction from low power magnification microscope objective lenses such as (10X and 40X) is negligible and not noticeable.

Thus, the 100x lens is immersed in a drop of oil placed on the slide to eliminate any air gaps and loss of light due to refraction as light passes through glass(slide) → air → glass(objective lens).

Describe the 3 layers of the mantle

Answers

Answer:

The 3 main layers are the core, mantle and crust

Explanation:

Answer:

I hope this is the answer for your question

Explanation:

Mantle is the widest section of the Earth. Its thickness is approximately 2,900 km. The mantle is mainly made up of semi-molten rock known as magma. The rock is hard in the upper part of the mantle, but lower down the rock is softer and begins to melt.

The mantle is located directly under the Sima. The mantle consists of very hot and dense rock. This layer of rock flows like asphalt under heavy weight. This flow is because of the greatest temperature differences from the bottom to the top of the mantle. The reason behind the plates of the Earth move is the movement of the mantle. Its temperature varies between 1600 oF at the upper part to 4000 oF near the bottom.
