Find the volume of the sphere. Either enter an exact answer in terms of \piπpi or use \dfrac{22}{7} 7 22 start fraction, 22, divided by, 7, end fraction for \piπpi.
Answers
Answer:
1,437.33
Explanation:
Volume of a sphere = 4/3πr³
π = 22/7
r = 7
Volume of a sphere = 4/3πr³
= 4/3 * 22/7 * 7³
= 4/3 * 22/7 * 7 * 7 * 7
= (4 * 22 * 7 * 7 * 7) / (3 * 7)
= 30,184/21
= 1437.3333333333
Volume of a sphere = 1,437.33

Explanation:
Hope This Helps If It Wrong Please Tell Me
A part of a reflecting telescope would you measure to find the aperture is the mirror.
What is a telescope?Scientists can observe celestial stars using a telescope. When collecting light, refracting telescopes use lenses, while reflecting telescopes utilize reflectors in order to observe an object.
The aperture in refractors refers to the thickness of the lens at the top of the tube. The diameter of the bottom tube's mirror, where light is collected, is used to measure reflectors.
White light is made up of a spectrum of colors, according to Isaac Newton, who developed his reflecting telescope as evidence for this theory in order to see far way objects.
The mirror size of a reflecting telescope is used to calculate the aperture. When selecting a telescope, the aperture—or the width of its primary mirror or lens—should be your primary consideration.

About one-third of the toxic metal, mercury (Hg), is released into the air from natural sources, such as rocks, soil, volcanoes, and the ocean. The remaining two-thirds comes from ____.
Answers
Answer:
Human activities
Explanation:
Anthropogenic activities account for the major sources of pollution of the environment. Various human activities contribute in no small way to environmental degradation.
Two-thirds of toxic metal, mercury (Hg) is released into the environment by human activities.
One of the human activities that release mercury into the environment is the extraction of metals such as sodium which requires an amalgam of sodium and mercury.
Mining and fossil fuel combustion also releases mercury in large quantities. This mercury so released leads to contamination of the environment.
A certain sample of limestone formed when shells from organisms were buried under layers of sediment and experienced pressure. A student classifies the sample as clastic sedimentary rock. What is one problem with this classification
Answers
Answer:
The problem with this classification is clastic sedimentary rocks are not formed with organic elements, that is, they do not form with the remains of organisms, such as shells, for example
Explanation:
The student made an incorrect classification. This is because he classified a rock formed from shells as clastic sedimentary rock.
Shells are organic materials, as they are the remains of living organisms. Organic material is not capable of forming clastic sedimentary rocks, as these rocks are formed only by sediments. Remains of organisms, manage to form a type of rock called organic rock.
what are the three types of materials that affect light differently
Answers
Answer:
Explanation:
The purpose of this lesson is for the students to learn that light interacts differently with different types of materials. Students will be able to categorize materials into 3 categories based on how the light interacts with those materials: transparent (light shines through), translucent (some light shines through, and opaque (no light shines through).
Answer:
Glass, plastic, mirrors="If a material is a light colour or has a smooth surface, more light will be reflected. Shiny opaque materials, such as mirrors, reflect most of the light that strikes them. If a material is a dark colour or has a rough surface, more light will be absorbed. Opaque objects that absorb light also become warm."

Horizontal variations in air pressure cause a force which makes the wind blow. These pressure variations are caused by a. warm temperatures in the stratosphere b. non-circular shape of Earth c. uneven heating of the Earth's surface d. greenhouse effect e. Earth's rotation
Answers
Answer:
The pressure gradient causes the air to move horizontally, forcing the air directly from a region of high pressure to a region of low pressure. The Coriolis force, however, deflects the direction of the flow of the air (to the right in the Northern Hemisphere) and causes the air to flow parallel to the isobars.

What interesting patterns did you notice between the various stakeholders in relation to the arguments for and against the Keystone XL Pipeline?
Answers
Hello. You did not submit the text to which this question refers, which makes it difficult for it to be answered. However, I will try to help you as best I can.
Keystone XL Pipeline was a pipeline installation project that originated in Canada but extended to the US. The installation of this pipeline was very controversial and spurred people against and in favor of the installation. It was normal that both the people who were against and those who were in favor presented opinion patterns that are opinions that are repeated in each group.
In the group in favor of installing the pipeline, we could see a pattern where people argued that this pipeline would create many jobs, improve countries' economies, and increase the flow of energy and oil in North America. In the group against installation, we could see a pattern, where people claimed that the installation of this pipeline would negatively impact nature and encourage the use of fossil fuels that would stimulate global warming.
