Can you see light if not why? Radiation within a certain, tiny spectrum of around 400 to 800 nanometers in wavelength, causes objects to be seen by we humans. We can’t see the reflected light from those objects but we can see the objects. If the light shines through something translucent it appears to glow. […]

Which two ways is energy measured?
Which two ways is energy measured? Which describes the two ways that energy is measured? in convection and in temperature. How is human energy measured? In human biol- ogy research, energy is most often measured in kilocalo- ries (kcal). Another common unit for measuring energy is the joule or the kilojoule [1 kilojoule (kJ) 5 […]
Which type of telescope is best?
Which type of telescope is best? As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. Dobsonian telescopes, which are reflectors with a simple mount, provide lots of aperture at relatively low cost. A larger aperture lets you see fainter objects and finer detail than […]
What causes light beams to be parallel?
What causes light beams to be parallel? A narrower beam of laser light spreads out more quickly than a wider beam. Only an infinitely wide beam (a plane wave) does not spread out, and therefore has parallel waves. Divergence is observed by shining a laser light on a wall and then seeing the spot grow […]
What is bead seating pressure mean on a tire?
What is bead seating pressure mean on a tire? Excessive bead seating pressure (in excess of 40 psi) places extreme stresses on the tire beads that are forced onto the rim flange in a distorted manner. Such stresses may cause damage to the tire components and may result in tire failure. NEVER INFLATE BEYOND 40 […]

Is oxygen atom stable or unstable? One oxygen atom is unstable since it has only 6 electrons in the outermost shell. For an atom to be stable it needs 8 electrons. So, for the oxygen atom to be stable it requires two more electrons in the valence shell. Which is the least stable Carbocation? methyl […]
