What are the disadvantages of using aluminum wire? The disadvantage of aluminum wiring is that it must be installed correctly to avoid the risk of house fires. When a current runs through aluminum wiring it causes the metal to expand. This creates a cycle of expanding and contracting called “cold creep.” In time, this can […]

Which can show resonance? Resonance is shown by toluene which contains alternate single and double bonds in a planar six-membered ring. Was this answer helpful? Why is ozone a resonance structure?

How do you calculate fuel cost per mile? Take the current per-gallon price of diesel ($2.10) and divide it by your truck’s miles per gallon. So, $2.10 divided by 5.7 equals 36.84 cents. If you round that number up, you are spending 37 cents on fuel for every mile your truck travels. How do you […]

How do you calculate perihelion? The perihelion distance P=a(1−e) and the aphelion distance A=a(1+e) where e=0.875 is the eccentricity. This gives a perihelion distance of 2.375AU and an aphelion distance of 35.625AU. How is Pericenter calculated? The angle from the ascending node to the pericenter, measured in the plane of the orbit….The eccentricity of an […]
