Hi! I really need help on these questions, it would be great if you can answer them!
1: Equilibrium
[] When two forces are equal in opposite directions, they are in a state of equilibrium
2: Friction
[] It can be hard to sometimes slide a paper across a table, roll a car across the ground, etc etc. This is because of a force called friction which resists motion
3: Displacement
[] Work is only "done" when the object or surroundings are having movement, or in motion, and this creates displacement
4: Force
[] A force is a push/pull in any direction, this is a simple definition so not much can be added.
5: Inertia
[] Inertia is a force that likes to remain unchanged, or without movement
6: Effort
[] "Meg is holding up weight without movement. She hasn't done any work since it did not move, but is tired. Why?" Effort! She still put in effort even though no "work" happened
7: Work
[] Force times displacement is the equation for work
8: Motion
[] Look back to #3, when there is motion we can tell work is done
Have a nice day!

What type of heat transfer is most important to maintaining a relatively stable
climate on Earth? Justify your answer.
The type of heat transfer that is most important to maintaining a relatively stable climate on Earth is known as solar radiation.
What is Heat transfer?Heat transfer may be characterized as the migration or transmission of heat across the border of the system due to an imbalance of difference in temperature between the system and its surroundings.
Solar radiations govern the principle and the entire process of heat transfer because it is the principle and fundamental source of heat and energy for the entire planet of the earth. These radiations initiate the process and pass down to the source artificial sources of heat transfer in physical life.
Therefore, solar radiation is a type of heat transfer that is most important to maintaining a relatively stable climate on Earth.

On a particular day, Denali had a temperature of -23°C at its peak and 13°C at its base. What could be the reason for this temperature difference?
A.
Temperature increases with an increase in altitude.
B.
Temperature decreases with an increase in altitude.
C.
The base is close to the Gulf of Alaska.
D.
The mountain receives lake-effect snow.
Answer:
B.) Temperature decreases with an increase in altitude.
As you climb a mountain, you can expect the air temperature to decrease by 6.5 degrees C for every 1000 meters you gain. This is called the standard average lapse rate.

When writing a scientific paper, look for the most credible sources. Science doesn’t show bias, but we humans tend to show bias. Beware of sites and articles that provide facts without proper scientific evidence. Avoid using information from such sites. You must be able to identify reliable sites so the data in your paper is credible.
Use sources that end in .gov (government sites), such as CDC.gov. They are reliable sources. You can also use sites ending in .edu. They can be deemed trustworthy, but sometimes the information is written by students rather than scientists. Always find out who the author of the article is before proceeding. Some .org and .com sites are credible, but you need to analyze the content to verify their authenticity. As you review a source, try to answer these questions:
Who authored the article?
Is this person a scientific expert in the species I’m researching?
What is the purpose of the article?
Does the article state facts that scientists can prove with evidence?
Are there opinions in the article?
How old is the article?
Do other credible sources support the statements in this article?

Explanation:
Cancer is the name given to a collection of related diseases. Cancer is more than one type of disease. In cancer, as a result of genetic mutations, this regulatory process malfunctions, resulting in uncontrolled cell proliferation. CAD, Stroke, Respiratory illness, COPD are all diseases related to cancer. Inherited genetic mutations play a major role in about 5 to 10 percent of all cancers. There are many environmental pathogenic factors that can cause cancer. For example , Tar and Coal-Tar Pitch , Emissions , Secondhand Tobacco Smoke (Environmental Tobacco Smoke) , Arsenic , Soot , Asbestos , Wood Dust. When cancer cells break away from a tumor, they can travel to other parts of the body through the bloodstream or the lymph system. Cancer is hard to treat in later stages because it probably has already spread through out the body. The grade of a cancer depends on what the cells look like under a microscope. In general, a lower grade indicates a slower-growing cancer and a higher grade indicates a faster-growing one. Some examples of cancer treatments of cancer are, Surgery, Chemotherapy, Radiotherapy, Cancer drugs, Hormone therapy, Stem cell and bone marrow transplants, Targeted cancer drugs. A new treatment involving a photosensitising agent that makes cells more sensitive to light and, by doing so, causes cancer cells to be destroyed when a laser light is directed on a cancerous area. One challenge is, druggable genomic alterations are diverse and represent only small subsets of patients in certain tumor types, which limits testing their clinical impact in biomarker-driven clinical trials. Next-generation sequencing technologies are increasingly being implemented for molecular prescreening in clinical research, but issues regarding clinical interpretation of large genomic data make their wide clinical use difficult.

By looking at the relative positions of the elements calcium, Ca, fluorine, F, sulfur, S, and oxygen, O, in the Periodic Table, which TWO descriptions are TRUE about calcium fluoride, CaF2, and sulfur dioxide, SO2?
CaF2 is an ionic compound, and SO2i is a covalent compound.
CaF2 is formed by covalent bonds, and SO2 is formed by ionic bonds.
CaF2 cannot conduct electricity when dissolved in water, but SO2 can.
CaF2 is a gas at room temperature, while SO2 has a high boiling point.
CaF2 has a high boiling point, while SO2 is a gas at room temperature.
CaF2 is soft at room temperature, while SO2 is hard and forms crystals.

Thus, Since the turn of the 20th century, glass has been made with calcium fluoride, a novel substance. It is a solid that dissolves readily in water and has a special physical and chemical makeup that makes it suitable for usage as a glassmaking material.
Glass used in windows, bottles, and other glass goods was formerly created from calcium silicates before the invention of this substance. The new glass, referred to as glass with added fluorides, has a number of advantages over calcium silicates, which have drawbacks that make them unsuitable for the creation of modern glass.
Calcium Fluorine is a naturally occurring element that is frequently found in rock, soil, plants, and animals.
