Is the starter relay supposed to click? The starter relay not only completes the electrical circuit, but it also boosts the battery’s current. If your starter relay has gone bad, the electrical signal will never make it from the battery to the starter motor. A faulty relay often produces an audible clicking sound when you […]

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? 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 […]

Does removing a catalytic converter make an engine consume more fuel? Some vehicles experience more fuel consumption. Some car owners are experiencing more fuel consumption after removing their catalytic converters. The explanation for this is because their vehicle’s O2 sensors readings are not correct which cause it to require more usage of fuel. Will removing […]

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? 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? 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 […]

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 […]
