How far away is a parsec in light years? 3.26 light years What can Parallax be used to calculate quizlet? Parallax measurements work by measuring the relative change in position of stars as the earth goes around the sun. Apparent Magnitude is the star’s brightness as it appears from earth. absolute magnitude is the apparent […]
Why are light bulbs brighter in a parallel circuit?
Why are light bulbs brighter in a parallel circuit? When the bulbs are in parallel, each bulb sees the full voltage V so P=V2R. Since a bulb glows brighter when it gets more power the ones in parallel will glow brighter. See, the parallel combination of resistors reduces the effective resistance of the circuit. Hence […]
What is the difference between daylight and bright white bulbs?
What is the difference between daylight and bright white bulbs? Bright white (4,000 to 5,000 Kelvin) is between white and blue tones. Daylight (5,000 to 6,500 Kelvin) has a more bluish tone. This light color will maximize contrast for colors, making it ideal for working, reading or applying makeup. What is standard light bulb size? […]
Why do things stick to glass?
Why do things stick to glass? The short answer is that glass–an amorphous compound containing primarily silicon and oxygen–tends to form something known as silanol on its surface. They form hydrogen bonds with liquid water, causing it to adhere to the surface of the glass very strongly. Why does water wet glass and mercury doesn […]

Which solid has the highest melting point?
Which solid has the highest melting point? tungsten Do impurities lower melting point? The presence of even a small amount of impurity will lower a compound’s melting point by a few degrees and broaden the melting point temperature range. Because the impurity causes defects in the crystalline lattice, it is easier to overcome the intermolecular […]
