What would a pulsar look like? From Earth, pulsars often look like flickering stars. On and off, on and off, they seem to blink with a regular rhythm. But the light from pulsars does not actually flicker or pulse, and these objects are not actually stars. Although the light from the beam is steady, pulsars […]
What kind of information does a life cycle cost LCC analysis provide?
What kind of information does a life cycle cost LCC analysis provide? Performing a life-cycle cost analysis (LCC) gives the total cost of a lighting system—including all expenses incurred over the life of the system. What is lowest life cycle cost? Lowest life-cycle cost (LCC) is the most straightforward and easy-to-interpret measure of economic evaluation. […]

What is matter fifth grade?
What is matter fifth grade? PROPERTIES OF MATTER DEFINITION. Matter is anything that has weight and takes up space. Everything you can see and touch is made up of matter. Matter exists in three main forms: solids, liquids, and gases. It also has properties that we can describe through density, solubility, conductivity, magnetism, etc. What […]
What is heating by convection?
What is heating by convection? Heat convection is a mode of heat transfer by the mass motion of a fluid such as air. Heat convection occurs to the surface of an object where the surrounding fluid of object is heated and moved energy away from the source of heat. What are the similarities of conduction […]
For what reason would a theory be changed or replaced?
For what reason would a theory be changed or replaced? A useful theory that has been tested and supported may become a dominant view among the majority of scientists. However, science is always changing. As new evidence is uncovered, a theory may be revised or replaced by a more useful explanation. Can a theory be […]
Which conditions are necessary for hydrogen fusion?
Which conditions are necessary for hydrogen fusion? Fusion requires temperatures of about 100 million Kelvin (approximately six times hotter than the sun’s core). At these temperatures, hydrogen is a plasma, not a gas. Plasma is a high-energy state of matter in which all the electrons are stripped from atoms and move freely about. What is […]
How many bonds can sulfur make with elements?
How many bonds can sulfur make with elements? two bonds Is Sulfur more electronegative than calcium? Sulfur is more electronegative than calcium. Is oxygen more electronegative than sulfur? Electronegativity. Sulfur is less electronegative than oxygen (2.4 and 3.5, respectively) and as a consequence bonds to sulfur are less polar than the corresponding bonds to oxygen. […]
