How did Planck explain blackbody radiation? All bodies radiate energy. The amount of radiation a body emits depends on its temperature. To explain the blackbody radiation curve, Planck assumed that the exchange of energy between radiation and cavity walls takes place only in discrete quanta of energy. How does Planck solve ultraviolet catastrophe? Solution. Albert […]
How do you create a row vector in Matlab?
What makes a control valve become linear equal percentage or quick opening control valve?
What makes a control valve become linear equal percentage or quick opening control valve? Linear valves are used in most applications except heat transfer (temperature control). Non-Linear Valves: If the valve gain rises as the valve opens, its characteristic is called equal percentage (=%) and if its gain drops as it opens, it is called […]
How do you find resistance with voltage and current?
How do you find the circumference of a screw?
How do you find the circumference of a screw? Calculate Circumference Calculate the circumference of the screw shaft by measuring the diameter of the screw and multiplying by pi. For example, if a screw has a diameter of 0.25 inches, then the circumference of the screw is 0.79 inches. How is IMA calculated? In general, […]
How does corrosion affect the environment?
How does corrosion affect the environment? In addition to our everyday encounters with this form of degradation, corrosion causes plant shutdowns, waste of valuable resources, loss or contamination of product, reduction in efficiency, costly maintenance, and expensive overdesign. It can also jeopardize safety and inhibit technological progress. What are the effects of corrosion? Some of […]
What is specific energy of flow?
What is specific energy of flow? The specific energy Es of a liquid in an open channel is the total mechanical energy (expressed as a head) relative to the bottom of the channel. The specific energy reaches a minimum value Es, min at some intermediate point, called the critical point, characterized by the critical depth […]
What is the source of materials for volcanoes that erupt in both ways How do you know?
What is the source of materials for volcanoes that erupt in both ways How do you know? On Earth, the erupted material can be liquid rock (“lava” when it’s on the surface, “magma” when it’s underground), ash, cinders, and/or gas. There are three reasons why magma might rise and cause eruptions onto Earth’s surface. Volcanoes […]
What is agricultural support?
What is agricultural support? Agricultural support is defined as the annual monetary value of gross transfers to agriculture from consumers and taxpayers arising from government policies that support agriculture, regardless of their objectives and economic impacts. What is agricultural production? Agricultural production is the use of crops and animal products to enhance human life sustainably. […]
How are veneer sheets made?
How are veneer sheets made? Nowadays Wood veneer production is highly automated. It takes place in several steps: the cutting to size, jointing (splicing) the Wood veneer leafs or sheets to form a Wood veneer surface (face), attaching the veneer face to substrate materials and the subsequent surface treatment. What kind of wood is under […]
