What cancels a sharp or flat?
A symbol called a natural. It resets the note to it's normal "white note" name. *Bar lines can also cancel sharps, naturals or flats. For example say you are in C major and for one measure you have an F sharp and you don't carry into the next measure with a tie, the bar line will automatically reset the F sharp into an F natural so sometimes a natural symbol is not needed*
What kind of education is required to be a mathematician?
A doctoral degree in mathematics usually is the minimum education needed, except in the Federal Government. Master's and Ph.D. degree holders with a strong background in mathematics and a related discipline, such as computer science or engineering, should have good employment opportunities in related occupations.

What subjects are needed to become an architect?
Subjects needed are physics and math.
How many octagons are needed to make an octagonal prism?
Two are needed at each end of the prism
What risks exist for the patient in undergoing a gallbladder X-ray?
There is a small chance of an allergic reaction to the contrast material. In addition, there is low radiation exposure. X rays are monitored and regulated to provide the minimum amount of radiation exposure needed to produce.
Does phone really have radiation that is harmful to humans?
Phones emit non-ionizing radiation, which is considered safe at normal levels. However, long-term exposure to high levels of this radiation may have potential health risks, though more research is needed to fully understand these effects. To minimize any potential risk, it is advisable to use hands-free devices and limit exposure by keeping phone calls short.
Which is a good source of vitamin d?
There is no known good natural source of vitamin D other than exposure to sunlight. If needed, there are always Vitamin D supplements, however these aren't as efficiently absorbed compared to the natural source.
Why do you need safety precautions when using radioactive sources?
Safety precautions are needed when using radioactive sources to prevent exposure to harmful radiation. This radiation can damage cells in the body and increase the risk of cancer. By following safety protocols, individuals can minimize their exposure and prevent health risks associated with radiation.
Can exposure to radiation from working in nuclear power cause parkinsons disease?
There is limited evidence linking radiation exposure from working in the nuclear power industry to an increased risk of Parkinson's disease. While some studies suggest a possible connection, more research is needed to establish a definitive link between the two. Other factors such as genetics and environmental exposures may also play a role in the development of Parkinson's disease.
What are the dangers to patients and personnel from ionizing radiation?
Ionizing radiation can disrupt biological processes within cells. It can cause cellular mutation or cellular damage, and can even kill a cell. This potential requires we consider shielding personnel from the radiation. As to a patient, that individual is being exposed to the radiation as part of an imaging or treatment plan, and a specialist will be on hand to insure that only the required or prescribed exposure is administered, and radiation protection, perhaps in the form of shielding blankets, is placed if needed over areas adjacent to the site the radiation is to be directed.
What kind of species can evolve from natural selection?
All kinds of species. After all, all species that doexist are the result, primarely, of natural selection.+++That includes us! We were originally an African primate but slowly diffused to many other parts of the world where we needed different approaches to exposure to solar radiation: hence our several different strains (races). One effect only fairly recently know is that different races have different susceptibilities to certain illnesses - again a matter of natural selection although one hard to understand.
For toxic chemical sustance to harm you repeat exposure is needed or a one time exposure will do harm on you?
it can hury you. it can hury you.
What background is needed to be a mineralogist?

What is needed for cosmologists to study the age of the universe?
The age of the universe goes back to the Big Bang. The Bang resulted in a release of energy in the form of radiation. Due to the expansion of the Universe since that time the original radiation has been red-shifted to the microwave range. The background microwave radiation is the best tool for studying the age of the universe.
What produce electromagnetic radiation?
in physics, electromagnetic radiation occurs when charged particles have forces acting on them to accelerate them. Electrons are responsible for the force needed to create electromagnetic radiation.
How do you store carbon-14?
Carbon-14 is typically stored as a gas or liquid in sealed containers to prevent contamination. It should be stored in a cool, dry place away from sources of heat and light. Special precautions may be needed to ensure safety and minimize exposure to radiation.
