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 […]

Does increasing effect size increase power?
Does increasing effect size increase power? The statistical power of a significance test depends on: • The sample size (n): when n increases, the power increases; • The significance level (α): when α increases, the power increases; • The effect size (explained below): when the effect size increases, the power increases. Why does increasing the […]
Does removing a catalytic converter make an engine consume more fuel?
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 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 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 […]
