Can electrons exist alone? Electrons have mass, charge, angular momentum, an intrinsic magnetic moment and helicity, but they have no known substructure. No two electrons can occupy the same space at the same time. They are part of every atom but they can exist separately on their own as well. What happens to the atoms […]
How do you calculate heat of combustion?
How do you calculate heat of combustion? The heat of combustion is calculated by multiplying the mass of the water times the specific heat of the water times the change in temperature. This entire equation is multiplied by -1, because heat of combustion is negative because heat is being lost or released. What is combustion […]
What is the difference between a resident set and a working set?
What is the difference between a resident set and a working set? What is the resident set and working set of a process? Resident set is that portion of the process image that is actually in real-memory at a particular instant. Working set is that subset of resident set that is actually needed for execution. […]
Why red is more energetic than yellow?
Why red is more energetic than yellow? Since, red light has lower frequency than yellow, yellow has higher momentum than red, not mass. In a way, it’s the momentum of photons which cause the radiation pressure. If the hotter an object, the brighter it glows (more energy), then why is a blue flame less visible […]

What happens to current If voltage is doubled?
What happens to current If voltage is doubled? if you increase the voltage (or electrical pressure) in a circuit then the current (flow of electrons) will increase in direct proportion, eg if you double the voltage the current flow will double. What if both voltage and resistance are doubled? and if the voltage and the […]
What happens if you fail fitnessgram?
What happens if you fail fitnessgram? What Happens If a Student Does Not Pass the FITNESSGRAM®? If the student passes the FITNESSGRAM® in grade ten, the local governing board or county superintendent may exempt the student from physical education for two years, grades eleven and twelve. How often are you supposed to complete the Fitnessgram […]
What causes static electricity in a person?
What causes static electricity in a person? Static electricity is created when positive and negative charges aren’t balanced. Protons and neutrons don’t move around much, but electrons love to jump all over the place! When an object (or person) has extra electrons, it has a negative charge. Why is my laundry so static? What causes […]
What is the difference between loudness and frequency?
What is the difference between loudness and frequency? Frequency (the number of vibrations or sound waves per second) is measured in Hertz (Hz). A sound that is 4,000 Hz (like the sound the letter “F” makes) has 4,000 waves per second. Intensity (loudness) is the amount of energy of a vibration, and is measured in […]
What are the advantages and disadvantages of coal power?
What are the advantages and disadvantages of coal power? Coal energy is an affordable energy source because of the coal’s stable price compared to other fuel sources. Coal is easy to burn. Coal produces high energy upon combustion. Coal energy is inexpensive. Why should we not use coal? In 2012, coal accounted for 37.4% of […]
