Do not stand too close to moving?

Do not stand too close to moving? “ When a train moves, there is a matter wave attached to it. Waves move from positive to negative. Outside of train is positive and inside is negative. So, the train may pull us towards it if we stand very close to it.” Why do we get pulled […]

What is F MA Math?

What is F MA Math? The famous formula is: F = ma. “Newton’s Second Law of Motion” (F is force, m is mass and a is acceleration) Do you need calculus for F MA? F=ma does not require any Calculus background. It is a test designed to challenge your understanding and intuitive on the most […]

What is the critical angle of ice?

What is the critical angle of ice? 49.8 degrees How do you find the critical angle in Snell’s law? The critical angle can be calculated from Snell’s law by setting the refraction angle equal to 90°. For any angle of incidence less than the critical angle, part of the incident light will be transmitted and […]

What is steam reforming process?

What is steam reforming process? Steam reforming or steam methane reforming is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water. Commonly natural gas is the feedstock. The main purpose of this technology is hydrogen production. The reaction is strongly endothermic (consumes heat, ΔHr = 206 kJ/mol). What is […]

What causes thermal noise?

What causes thermal noise? Thermal noise is generated as a result of thermal agitation of the charge carriers which are typically electrons within an electrical conductor. This vibration is dependent upon the temperature – the higher the temperature, the higher the agitation and hence the thermal noise level. How is thermal noise calculated? The magnitude […]

What is visible on the moon?

What is visible on the moon? One side of the moon always faces Earth. Even so, over time, it’s possible to see as much as 59% of the moon’s surface, due to lunar libration. Lunar libration lets us see more than 50% of the moon. One half of the moon always faces Earth, and one […]

Are Heavier arrows more accurate?

Are Heavier arrows more accurate? All factors remaining equal, heavy arrows always are more reliable, more durable, than lighter. More material, with additional layers of carbon material, equal more strength when subjected to abuse such as bone impacts or when shot into rocky ground or bounced off trees following misses. What happens if arrow spine […]

What is a healthy relationship with family?

What is a healthy relationship with family? In healthy family relationships, people trust and rely on each other for support, love, affection and warmth. Families often share common goals and work together to reach those goals (for example, children and young people may help their families get the dinner dishes done so that everyone can […]

What is the charge of an electron?

What is the charge of an electron? Electrons. Electrons are found in the periphery of the atom and have a charge of -1. They are much smaller than protons; their mass is 11836 amu. Typically in modeling atoms, protons and neutrons are regarded as stationary, while electrons move about in the space outside the nucleus […]
