Does Heat travel up or down? “Heat” does not travel up. Heat can travel in all directions. The direction heat travels depends on the specifics of a system not in thermal equilibrium. In contrast, “hot air” on earth’s surface tends to go up. What material reflects the most heat? Note that a metal will only […]
What motion is illustrated by a ball thrown horizontally?
What motion is illustrated by a ball thrown horizontally? Objects experiencing projectile motion have a constant velocity in the horizontal direction, and a constantly changing velocity in the vertical direction. The trajectory resulting from this combination always has the shape of a parabola. What are the standard assumptions we make for horizontally launched projectiles? Assumptions […]

What are the three main physical properties of sound waves?
What are the three main physical properties of sound waves? Sound waves are changes in pressure generated by vibrating molecules. The physical characteristics of sound waves influence the three psychological features of sound: loudness, pitch, and timbre. Loudness depends on the amplitude,or height, of sound waves. The greater the amplitude, the louder the sound perceived. […]

How high or low a sound seems to a listener is its?
How high or low a sound seems to a listener is its? How high or low a sound seems to a listener is its pitch. Pitch, in turn, depends on the frequency of sound waves. High-frequency sound waves produce high-pitched sounds, and low-frequency sound waves produce low-pitched sounds. Infrasound has wave frequencies too low for […]
How much light is there in the universe?
How much light is there in the universe? According to calculations, the current comoving distance—proper distance, which takes into account that the universe has expanded since the light was emitted—to particles from which the cosmic microwave background radiation (CMBR) was emitted, which represents the radius of the visible universe, is about 14.0 billion … How […]
What is a disadvantage of using nuclear power?
What is a disadvantage of using nuclear power? Disadvantages of Nuclear Power The further implementations of nuclear power are limited because although nuclear energy does not produce CO2 the way fossil fuels do, there is still a toxic byproduct produced from uranium-fueled nuclear cycles: radioactive fission waste. What is the cheapest form of electricity? solar […]
What are the two classification of knowledge?
What are the two classification of knowledge? Within business and KM, two types of knowledge are usually defined, namely explicit and tacit knowledge. The former refers to codified knowledge, such as that found in documents, while the latter refers to non codified and often personal/experience-based knowledge. What are the 3 types of teachers knowledge? In […]
