What is relation between alpha and gamma? Linear expansion – α Cubical / Volumetric expansion – γ Thus, the relation between linear expansion and cubical expansion is, γ = 3α What is the relation between I and Alpha? Derive the equation, α=i-1n-1. Derive a relation between degree of dissociation and van’t Hoff factor. At start, […]

What things reduce friction?
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 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 […]
Why is light red shifted?
Why is light red shifted? Light behaves like a wave, so light from a luminous object undergoes a Doppler-like shift if the source is moving relative to us. However, to be accurate, the red shifts observed in distant objects are not exactly due to the Doppler phenomenon, but are rather a result of the expansion […]
How long does it take to drive 120 miles at 60 mph?
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 […]
Why does binding energy decrease?
Why does binding energy decrease? The above figure illustrates that as the atomic mass number increases, the binding energy per nucleon decreases for A > 60. As the repulsive forces are increasing, less energy must be supplied, on the average, to remove a nucleon from the nucleus. In other words, the BE/A has decreased. What […]
Is speed a unit?
Which is a better absorber of heat white or black?
Which is a better absorber of heat white or black? The amount of energy absorbed and radiated is decided by the colour. White is a good reflector while black is a good absorber of heat. Among other colours there is a gradation of temperature. The only difference between them is the colour with which they […]
