Were there any factors that influenced the smoke or fire effluent occurrence of the extreme fire behavior phenomenon? The primary variables influencing fire development and extreme fire behavior in a compartment fire are fuel characteristics and availability, ventilation profile, and compartment characteristics and configuration (see Figure 8). What are the 7 factors that affect fire […]

What is the work done by the electric force to move a 1 cc charge from A to B? Thus, the work done by electric force to move a 1 C of charge from point A to point B is 0 J. What is the work done by the electric force? The work done by […]

In which biome Do animals have a thick layer of fat to keep them warm? marine In which biome would you expect to find many coniferous trees? taiga biome Which is a reason that a plant from a rain forest biome would not survive in a desert biome? Pick two reasons that a plant from […]

When an alpha particle is emitted from an unstable nucleus the atomic mass number of the nucleus? Protons are positively charged. When a nucleus emits an alpha particle, these changes happen: the mass number decreases by 4. the atomic number decreases by 2. When an α particle is emitted by an unstable nucleus the atomic […]

What do particles look like in a gas? Particles in a: gas are well separated with no regular arrangement. liquid are close together with no regular arrangement. solid are tightly packed, usually in a regular pattern. When gases are squashed particles? Because the particles are moving about, a gas will fill any container that it […]

In what direction do you notice the jet streams moving? The reason that they most often move from west to east is due to the jet stream. The jet stream is a narrow band of fast, flowing air currents located near the altitude of the tropopause that flow from west to east. Why do jet […]

What do you mean by miscible liquid? A miscible liquid can be mixed with another liquid without separating from it: Alcohol is miscible with/in water. Compare. immiscible. What are miscible liquids give example? Two liquids that appear to mix completely together are said to be miscible. Water and ethanol are one example of a pair […]

How do you find your mass number? Together, the number of protons and the number of neutrons determine an element’s mass number: mass number = protons + neutrons. If you want to calculate how many neutrons an atom has, you can simply subtract the number of protons, or atomic number, from the mass number. How […]

Do older stars have heavier elements? In the scorching interior of these stars, hydrogen and helium melted together and formed the first heavier elements like carbon, nitrogen and oxygen, and after a few hundred million years, all of the known elements were in place. … Can All Stars produce heavy elements Why or why not? […]

Why the radius of an atom Cannot be measured directly? The atomic radii cannot be measured directly because the electron cloud surrounding the nucleus does not have a clearly defined…. Why is it not possible to determine accurately the atomic radius of an element? Determining the atomic radii is rather difficult because there is an […]
