How much heat and pressure is needed for fusion? Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun’s core). At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about. […]
How can extinction affect humans?
How can extinction affect humans? As species disappear, infectious diseases rise in humans and throughout the animal kingdom, so extinctions directly affect our health and chances for survival as a species. The rise in diseases and other pathogens seems to occur when so-called “buffer” species disappear. Is extinction good or bad? Nevertheless, extinctions can have […]
What is the wavelength of 1 hertz?
What is a mass defect and why is it important?
What is a mass defect and why is it important? The nuclear mass defect is a fundamental property of a nucleus and is a fixed value corresponding to a certain amount of binding energy for that nucleus. Mass defect and binding energy are important factors in the energy involved in nuclear reactions. Is binding energy […]
What are the special VFR minimums?
What are the special VFR minimums? If the reported weather is less, a pilot can request a Special VFR Clearance. Several conditions must be met; the visibility must be at least one statue mile, the pilot must remain clear of clouds and at night, the pilot must be instrument rated in an IFR capable aircraft. […]
Why Hall voltage is negative?
Why Hall voltage is negative? In metals, the Hall voltages are generally negative, indicating that the electric current is composed of moving negative charges, or electrons. What is the value of Hall coefficient? The average value of the Hall coefficient was measured to be 0.0113±0.0002m3C−1 and sign of the Hall coefficient was positive corresponding to […]
Can you suddenly become farsighted?
Can you suddenly become farsighted? Signs and Symptoms of Presbyopia The most common symptom of presbyopia is the sudden onset of farsightedness, meaning that your near vision will be blurry while your distance vision will be clearer by comparison. What is worse nearsighted or farsighted? Nearsightedness means that your cornea might have a greater-than-average curvature, […]
What is the percentage of radioactive nuclei left after 3 Half Lives pass?
What is the percentage of radioactive nuclei left after 3 Half Lives pass? Thus the half-life of a nuclear decay process is the time required for the number of unstable nuclei to decrease from [A]0 to 1/2[A]0….Radioactive Decay Rates. Number of Half-Lives Percentage of Reactant Remaining 2 50%2=25% 12(12)(100%)=25% 3 25%2=12.5% 12(12)(12)(100%)=12.5% n 100%2n (12)n(100%)=(12)n% […]
What is the angle of reflection for normal incidence?
How do rivers become larger as they travel across the land?
How do rivers become larger as they travel across the land? 1 Answer. Tributaries combine, adding water to rivers. A tributary is a stream that flows into a larger river. Small streams from around an area combine together to form a bigger tributary that eventually falls into rivers. What kind of organism makes up the […]
