Can a body have zero velocity and still acceleration give example?
Can a body have zero velocity and still acceleration give example? Yes, a body with a velocity 0 can still accelerate. The simplest example is a body which is thrown up. At the peak point its velocity becomes 0 but still accelerates due to gravity. How can you have acceleration but no velocity? Since acceleration […]
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 […]
