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.

How many octagons are needed to make an octagonal 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.
Additional information needed for carbon dating?
To perform carbon dating, we need a sample that contains organic material that was once alive, such as wood, bone, or charcoal. The sample must be carefully collected and preserved to avoid contamination. We also need to know the approximate age of the sample to determine the appropriate method and laboratory to use for analysis.
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.
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.
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 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.
What background is needed to be a mineralogist?

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.
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.
Is biology class needed to become a radiation therapist?
100% yes.
Is it same the radiation used for communication and harmful in mobile?
The radiation used for communication in mobile phones is the same type of radiation that is classified as a possible human carcinogen by the World Health Organization (WHO). However, the levels of radiation emitted by mobile phones are considered to be low and not a significant health concern. However, it's important to consider the long term exposure to mobile phone radiation, Some studies have shown that long-term exposure to RF radiation may increase the risk of certain types of cancer, such as brain tumors, although more research is needed to confirm these findings. It's also worth noting that some people may be more susceptible to the effects of RF radiation, such as pregnant women and children. Overall, while mobile phone radiation is considered to be low and not a significant health concern, it is still important to be aware of the potential risks and take steps to reduce your exposure, such as using a hands-free device, keeping your phone away from your body when not in use, and limiting the amount of time spent on your phone. my recommendation to protect yourself is: ʜᴛᴛᴘꜱ://ʙɪᴛ.ʟʏ/ᴇᴍꜰᴅᴇꜰᴇɴᴅᴇʀ
