Do phonons actually exist? Phonon is considered a quasi-particle, beacuse it can exist only in solids as a consequence of vibrational motions: they cannot propagate in vacuum. > as a consequence of vibrational motions: they cannot propagate in vacuum. Do phonons have mass? A phonon — a particle-like unit of vibration that can describe sound […]
Is snow a type of condensation?
Is snow a type of condensation? Condensation is a phenomenon that occurs when air shrinks so much that it is no longer able to capture and hold humidity. Water molecules are pressed (forced) out of the spaces between the air molecules. As a result, we see vapor (e.g. “giving out”, damping, dew, mist, clouds) or […]

Capsizing, swamping, sinking, or running aground. Being involved in a collision. Operating a pleasure craft while under the influence of alcohol or drugs. Can you drown if you fall asleep in the […]
How does temperature affect ideal gas law?
How does temperature affect ideal gas law? As the temperature increases, the average kinetic energy increases as does the velocity of the gas particles hitting the walls of the container. The force exerted by the particles per unit of area on the container is the pressure, so as the temperature increases the pressure must also […]
What is experiment in data collection?
What is experiment in data collection? Experiment. An experiment is a controlled study in which the researcher attempts to understand cause-and-effect relationships. The study is “controlled” in the sense that the researcher controls (1) how subjects are assigned to groups and (2) which treatments each group receives. What is the purpose of data in an […]

What happens when you wrap a wire around a nail?
What happens when you wrap a wire around a nail? By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the […]
What is change in motion called?
What is change in motion called? Speed and direction of motion is velocity. A change in speed is a change in velocity – so, a change in speed is an example of acceleration! Page 2. Acceleration may be positive or negative. Negative acceleration is sometimes called deceleration. What is the rate change in velocity? The […]
At which plate boundary do earthquakes occur most often?
At which plate boundary do earthquakes occur most often? convergent boundaries Where is the most dangerous place to be during an earthquake? Move away from buildings, streetlights, and utility wires. Once in the open, stay there until the shaking stops. The greatest danger exists directly outside buildings, at exits and alongside exterior walls. Where is […]
