What is the difference between rising and sinking air? Rising air always cools, and, conversely, sinking air always warms. This type of temperature change, which is caused simply by ascent or descent in the atmosphere, is called adiabatic cooling or warming. When air moves vertically, its pressure changes. What is the diff between climate and […]
Is any closed conducting path?
Is any closed conducting path? There must be a closed conducting loop from the positive to the negative terminal in order to establish a circuit and to have a current. When this occurs, the circuit is opened and a closed conducting loop no longer exists. Without a closed conducting loop, there can be no circuit, […]
How far away is a parsec in light years?
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 […]

How dangerous is a whirlpool?
How dangerous is a whirlpool? Whirlpools can be very dangerous and can cause drowning. Despite the danger, whirlpools are a fascinating natural phenomenon. Many people enjoy watching strong maelstroms spin away from the safety of dry land. Can you die from a whirlpool? The power of natural whirlpool is often exaggerated by fiction, as there […]

What are the uses of units in our daily life?
What are the uses of units in our daily life? Measurement provides a standard for every day things and processes. From weight, temperature, length even time is a measurement and it does play a very important role in our lives. The money or currency we use is also a measurement. And think of the rumble […]
