What things reduce friction? Silicone aerosols, oils, grease and ball bearings are all used to reduce friction. Air resistance force is the force of air pushing against a moving object. Air resistance (also called drag) is a type of frictional force. Who invented Maglev? Maglev — short for magnetic levitation — trains can trace their […]

What is the danger zone for food in degrees?
What is the danger zone for food in degrees? The danger zone is the temperature range in which food-borne bacteria can grow. Food safety agencies, such as the United States’ Food Safety and Inspection Service (FSiIS), define the danger zone as roughly 40 to 140 °F (4 to 60 °C). What kind of salt do […]

What is unit for flow rate for gases?
What is unit for flow rate for gases? Gas mass flow rate is the actual mass of a gas which moves through a measurement instrument per unit of time. Its units are usually in standard liters per minute (slpm) or standard cubic centimeters per minute (sccm) in SI units. The most common English units include […]
Is speed a unit?
Why do I feel sick during a storm?
Why do I feel sick during a storm? Approaching storms lower the air pressure. When atmospheric pressure decreases body tissues swell slightly. This can put increased pressure on joints and sinuses. Low temperatures also causes blood viscosity, or thickness. Does thunder affect mood? Thunderstorms are dramatic events, so it’s not surprising that they often bring […]
Can a bad fuel pump cause vapor lock?
Can a bad fuel pump cause vapor lock? Still, a modern fuel-injected system can suffer from vapor lock, not only if pressure in the fuel line drops (faulty fuel pressure regulator or fuel pump, for example) and the fuel line is subjected to high temperatures, but also modern engines that may reach between 248 and […]
What is the most important force driving erosion?
What is the most important force driving erosion? Water Erosion Water is the most important erosional agent and erodes most commonly as running water in streams. However, water in all its forms is erosional. Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. What is the biggest driver for soil […]
