Why is public transport safer than cars? Crash Risk Crash risk refers to property damages, injuries and deaths caused by vehicle crashes. Public transit has relative low crash rates per unit of travel, as indicated in Table 3 and Figure 1. Public transit passengers have far lower traffic casualty rates than automobile occupants. Should buses […]
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 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 […]

How fatigue crack is detected using edge current inspection?
How fatigue crack is detected using edge current inspection? Fatigue cracks tend to occur at bolt-jointed structures on an aircraft. In order to detect the damage quantitatively, a kind of change-prone micro eddy current sensor is designed and fabricated with flexible printed circuit board (FPCB) technology. Which wave is used in metal cracks detection? Ultrasonic […]

Which nerve sends to brain?
Which nerve sends to brain? For example, sensory neurons send information from the eyes, ears, nose, tongue, and skin to the brain. Motor neurons carry messages away from the brain to the rest of the body. Which finger connects to brain nerve? The fingers of our right hand are controlled by our Left brain while […]
