What is fatigue fracture? Fatigue fractures (also known as overuse fractures) are a type of stress fracture due to abnormal stresses on normal bone. They should not be confused with an insufficiency fracture, which occurs due to normal stresses on abnormal bone. What are fatigue beach marks? “Fatigue Stritations & beach marks” Fatigue striations are […]
What is typically the first step in a risk management process?
What is typically the first step in a risk management process? Five Steps of the Risk Management Process Step 1: Identify the Risk. The first step is to identify the risks that the business is exposed to in its operating environment. Step 2: Analyze the Risk. Step 3: Evaluate or Rank the Risk. Step 4: […]
How does a water to water heat pump work?
How does a water to water heat pump work? They absorb heat from outside air and release that heat into a forced-air distribution system within the building. The heat is moved using a standard vapor-compression refrigeration cycle. Cold liquid refrigerant is evaporated within the outside heat exchanger. Why is a heat pump called a heat […]
What is electrical analogy in heat transfer?
What is electrical analogy in heat transfer? Heat conduction in solids is similar to the conduction of electricity in electrical conductors in many aspects. In a conductor, the flow of electricity is driven by a potential difference and so is the flow of heat driven by a difference in temperature. What is meant by thermal […]
What foliated rock has the highest metamorphic grade?
What foliated rock has the highest metamorphic grade? Gneiss Is Schist a high grade metamorphic rock? Schist is a still higher degree of metamorphism, characterized by coarse grained foliation and/or lineation, with mica crystals large enough to be easily identified with the unaided eye. Low-grade metamorphic rocks tend to be fine-grained (the newly formed metamorphic […]
What is an alloy of iron and carbon called?
What is an alloy of iron and carbon called? steel Which metals are used in alloys? What are Some Common Alloying Elements? Chromium is a metal frequently used to help alloys resist corrosion. Nickel is a metal often added to materials to increase toughness. Copper is a metal used to make materials, such as aluminum, […]
What is the temperature of liquid boils or vaporized?
What is the temperature of liquid boils or vaporized? The boiling point of a liquid varies according to the applied pressure; the normal boiling point is the temperature at which the vapour pressure is equal to the standard sea-level atmospheric pressure (760 mm [29.92 inches] of mercury). At sea level, water boils at 100° C […]
How do you use multidimensional scaling?
How do you use multidimensional scaling? Basic steps: Assign a number of points to coordinates in n-dimensional space. Calculate Euclidean distances for all pairs of points. Compare the similarity matrix with the original input matrix by evaluating the stress function. Adjust coordinates, if necessary, to minimize stress. How do you do multidimensional scaling in SPSS? […]

Production and Manufacturing plants are the biggest sources of thermal pollution. Soil Erosion. Deforestation. Runoff From Paved Surfaces. Natural Causes. Retention Ponds. Domestic Sewage. What is thermal pollution and its effects? The Effects […]
Which fires can you use water to put out?
Which fires can you use water to put out? Class A fires are the easiest to put out and you can use a water or foam extinguisher. The fire is smothered by extinguishing the fire’s heat supply. Class B fires involve flammable liquids rather than solids. Common causes for these fires include gasoline, alcohol, and […]
