In both the Japanese and San Francisco earthquakes, fire killed more people than collapsing buildings. Why do you think this was the case?

Answers

In both the Japanese and San Francisco earthquakes, fire killed more people than collapsing buildings. This was probably a result of the both cities having most buildings constructed of wood, rather than a more fire proof material. The wood buildings fueled the fires rather than slowing them and trapped the people inside with no escape route. Although plenty of buildings collapsed during both earthquakes, fire is more lethal than debris and people could stay alive under rumble long enough until help came whereas the large fires in the cities made it hard for rescuers to keep people alive in burning buildings.

3. The volume of a gas is reduced from 4 L to 0.5 L while the temperature is held
constant. How does the gas pressure change?

Answers

Answer:

The new pressure is 8 times the original pressure.

Explanation:

Data obtained from the question include:

Initial volume (V1) = 4L

Final volume (V2) = 0.5L

Initial pressure (P1) = P

Final pressure (P2) =..?

The new pressure can be obtained by using the Boyle's law as shown below:

P1V1 = P2V2

P x 4 = P2 x 0.5

Divide both side by 0.5

P2 = P x 4 / 0.5

P2 = 8P

Therefore, the new pressure is 8 times the original pressure.

Qualitative data is descriptive information that cannot be measured in numbers. So among the choices, only discoloration amount is descriptive and cannot be measured.

The type of data which will be considered as qualitative data is discoloration amount.

What is qualitative data?

Qualitative data is that data which depends on the quality not in the quantity of any object.

Diameter, travelled distance and density are the quantitative data means they all depends on the quantity and measurement. Whereas the discoloration amount is the qualitative data as it is not measurable and not depends on the quantity.

List the five physical phase changes of matter and give one example for each.

Answers

Answer:Melting.

Freezing.

Evaporation.

Condensation.

Sublimation.

Explanation:

Answer: Examples for the five transformations previously given.

For the first four, we encounter common examples in everyday life, all to do with water:

Freezing - liquid to solid, e.g. water to ice, e.g. making ice cubes.

Melting - solid to liquid, e.g. ice to liquid water, melting ice cubes or snow flakes.

Condensation - gas to liquid, e.g. water vapor (gas) to liquid - water vapor in air (humidity) condenses to form liquid droplets on the outside of a cold beverage glass on a hot humid day; or cloud formation in the atmosphere.

Evaporation - liquid to gas, e.g. liquid water on clothes evaporates as clothes dry on clothesline or in dryer

While water can sublime under certain conditions of temperature and pressure, it is less evident in everyday life. Carbon dioxide however is a more common example.

Sublimation - solid to gas, e.g. "dry ice" disappearing. The visible smoke associated with dry ice is most likely just condensing water vapor in the air as the solid carbon dioxide cools the air.

Answers

Answer:The statement that best describes the motion of dye molecule in water is directed from a region of high to low concentration. The motion of the particles of the dye in water is described as diffusion: diffusion is the movement of molecules of a substance from one position to another.

Explanation:

Option A is correct. The statement that best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".

The motion of dye molecules in water is known to be random. Another name for random motion is Brownian motion and since diffusion is also Brownian motion, hence we can term the motion of the dye molecules in the water as "diffusion".

The water is held together by intermolecular forces and these forces are the ones that attract the molecules of the die carrying them away and making the process of molecular transport of the dye to be accelerated (moving from a region of high concentration to low concentration).

In conclusion, the statement best describes the motion of the dye molecules in the water is "the dye molecules move in a directed way from high to low".

In the 1700s, Isaac Newton determined that the force of gravity between two objects depends on the mass of the objects and distance between them. He reasoned that things fall toward Earth because it has so much mass. Then in the 1900s, Albert Einstein worked with new discoveries, such as the fact that light always travels the same speed, and he determined a new explanation of how and why gravity works. Mass and distance still matter in Einstein’s explanation, but speed also matters. Newton’s explanation still works for objects close to Earth, but Einstein’s explanation works for all of the objects in the universe.

A student is looking at a model of a neutral atom. The model shows that the atom has 19 subatomic particles in the nucleus. Ten of those subatomic particles do not have a charge.

Which statement about the model of the atom is true?

Answers

Answer:

The atom has 9 electrons

Explanation:

I don't see a list of possible choices, but as for what I can guess this is the correct answer. An atom with the same number of electrons as protons will be neutral, as stated in the problem. If this isn't what you are looking for. some other possible answers are the atomic weight will be 19, the atom has 10 neutrons, the atom has 9 protons, and the atom is a fluorine atom.

An atom generally consists of three important subatomic particles. They are protons, neutrons and electrons. Here the given atom has 19 subatomic particles, 10 of them are chargeless. So the atom is Fluorine.

What are subatomic particles?

The particles which are smaller in size than an atom are defined as the subatomic particles. The positively charged subatomic particles are called the protons whereas the negatively charged particles are called the electrons. The neutrons does not have a charge.

The number of protons or electrons in an atom is the atomic number. Here the atomic number of Fluorine is 9, so it has 9 protons and electrons. The atomic mass of fluorine is 19.

The number of neutrons in Fluorine is given as:

No: of neutrons = Mass number - Atomic number

19 - 9 = 10

Thus the given atomic model is of Fluorine.

Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O

Answers

Answer:

Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.

CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.

N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.

NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.

H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.

Overall, the scale can be represented as follows:

100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent

Toronto-based Michi, started six years ago by Michelle Watson and it has become high-end competition for Lululemon. Ardith, opened by Miranda Bryden in January 2015 is spare in presentation and clear-headed in its objective: to offer what Bryden calls "gym to the street" fashion in a boutique setting. It's the lines Bryden carries that must keep Lululemon designers worried. From London's Lucas Hugh laser-cut leggings (the brand is renowned for its high-end technical wearand it gained considerable media coverage for designing the training gear for The Hunger Games: Catching Fire) to the designed-and-manufactured-in-Toronto Michi line, which somehow manages to blend allure, empowerment and athletic prowess. It's worth noting that Michi is one of the lines carried by Bandier, the new retailer that has caught the notice of Forbes magazine for its high-end multi-brand incursion into athletic wear, or maybe street wear. The growing chain is run by a woman, Jennifer Bandier. In a New York Times interview last week, Bandier was described as a fitness-wear seeker who wanted her clothes "to be as stylish as the Frame Denim and Isabel Marant she prefers." Bandier carries Lucas Hugh, with its careful detailing and sometimes-stratospheric prices. The line's Nordica leggings are priced at $420 (U.S). At Ardith, Lucas Hugh pants start at $220 and top out at $320 for its "spark" print pant, made from custom fabric. To complete their strategy, Michi promotes its product line using advertising commercials with several Social Media players. "Our customers are busy women with busy schedules," Lucas Hugh founder Anjhe Mules told the Telegraph last year in addressing the pricing issue. "They are committed exercisers who'd spend that much on a pair of jeans, but actually they wear their gym gear more." Miranda Bryden digs into other aspects of this building upheaval in the market let's call it the luxury fitness-wear market. Fabric sourcing. Milling. Place of manufacture. "It's another consideration for people carefully considering their environment when buying," Bryden says.. What does all this mean for Lululemon? Not all that long ago, Lululemon with their Yoga pants was deemed the strongest supplier of yoga wear using premium prices, selling through their own retail stores and advertising in sports magazine and Television commercials. In the past decade, that market has become increasingly fractured, with Lululemon finding itself somewhere in the middle, having lost something of its high-end image in the market.
