Does anti glare coating wear off? The average AR coating should last about 2 years in my experience under moderate temperature and cleaning abuse,but if you are exposing your glasses to more extremes they could break down within a few months. Can I put anti glare on my glasses myself? Can I Add Anti-Reflective Coating […]
What is a join between atoms called?
What is a join between atoms called? When two electrons are shared between two neighbouring atoms, they are said to be joined by a covalent bond. When covalent bonds form between atoms, the resulting entity is called a molecule with a fixed characteristic geometry. What is the basic unit of matter? In turn, the atom […]

What are 3 uses of beryllium?
What are 3 uses of beryllium? Beryllium is alloyed with copper or nickel to make springs, gyroscopes, electrical contacts, spot-welding electrodes and non-sparking tools, according to the Royal Society of Chemistry. Other beryllium alloys are used in high-speed aircrafts and missiles, as well as spacecraft and communication satellites. Why is beryllium so expensive? Beryllium is […]
What are two characteristics of a compound?
What are two characteristics of a compound? Components in a compound are present in a definite proportion. It has a homogeneous composition. Particles in a compound are of one kind. A compound is made up of one or more atoms of the same or different elements. In a compound the elements are present in a […]
Is 1 degree Celsius cold or hot?
Is 1 degree Celsius cold or hot? In the Celsius scale there are 100 degrees between the freezing point and the boiling point of water compared to 180 degrees in the Fahrenheit scale. This means that 1 °C = 1.8 °F (check the section about temperature differences below). What is the coldest Fahrenheit temperature? The […]

Which is better Frye or Daubert?
Which is better Frye or Daubert? Under Frye, the scientific community is essentially the gatekeeper determining evidence admissibility. Using the strict standard, if the scientific community finds a method or theory acceptable, the court must admit the evidence. While Frye offers a bright line rule, Daubert provides courts with flexibility. What is the main difference […]
What kind of a wave is sound?
What kind of a wave is sound? These particle-to-particle, mechanical vibrations of sound conductance qualify sound waves as mechanical waves. Sound energy, or energy associated with the vibrations created by a vibrating source, requires a medium to travel, which makes sound energy a mechanical wave. How ECHO is created? An echo is made by sound […]
How many PSI is a brake line?
How many PSI is a brake line? Metal brake lines must withstand 5000 psi tests, and most burst around 15,000 psi. Typical full-lock operating pressures on conventional OEM-style automotive hydraulic-brake systems are 900–1,000 psi (69 bar) with manual brakes and 1,400-plus psi (96 bar)with power-assisted brakes. Is it illegal to use compression fittings on brake […]
