How much heat and pressure is needed for fusion?
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. […]
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 […]

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 […]
