1) A view of database that appears to an application program is known as : a) schema b) message c) virtual table d) none of above

Answers

Answer 1

Answer: D) None of the above

Explanation: The subschema differs from the schema in that one denotes the appearance of data in the Database Base Management System (DBMS) while the subschema which is also referred to as the external schema is that subset of the schema is visible or relevant to the user. Thus, It is the view of the database which is visible to an application program. Virtual tables in a database usually represents an object structures like a table which is the result of running certain database commands or functions such as the create table, view, select and so on. Virtual tables are not stored directly in database files.

How did the Soviet people lose their freedom to communist

Answers

1) The Soviet People of the Union of Soviet Socialist Republics never "lost their freedom". The Soviet people distinguished the people starting from the era of the U.S.S.R to the fall of the U.S.S.R in 1991.

The people of Eastern Europe and Russia lost their freedom to the Communist Regime, as they failed to find more common ground then just hatred to the Communist. Many times, these different groups (commonly known as "White Russians"), also fought against each other, which furthered weakened the military strength of the anti-communists. Foreign aid usually fell into the hands of corrupt officials, and rarely was used to help in the war effort. Without a better common goal, and the failure to run an adequate army and government, the White Russians lost and were expelled or absorbed into the Soviets.

Summarize the relationship between the composition, temperature, and volatile content of magmas and effusive vs. explosive eruptions.

Answers

Answer:

The relations can be explained by the nature of eruption and lava type.

Explanation:

The volatile content of magma is made up of small amounts of gas and water that is released as pressure is removed. The magmas formed by the partial melting often have rich volatile contents. A high volatile content decreases the viscosity of magma. The eruption is going to be explosive if the magma is viscous and volatile-rich.   The effusive eruption is a type of eruption were the lava steadily flows out of the volcano on the ground, they are most common in basaltic magmas and occurs immediately. The gases are dissolved in magmas due to high pressure. While in explosive eruptions the magmas are expelled out of the volcano's most violently when pressure is suddenly lowered at the vent. They can send the dut, rocks and pyroclastic matter up to 20 km in the atmosphere at the rate of 100,000 tonnes per second.

Scientists propose placing seismic stations on the floor of the Pacific Ocean to warn threatened coastal communities on the northwestern coast of the United States of approaching tidal waves caused by earthquakes. Since forewarned communities could take steps to evacuate, many of the injuries and deaths that would otherwise occur could be avoided if the government would implement this proposal.
The answer to which of the following questions would be most important in determining whether implementing the proposal would be likely to achieve the desired result?
(A) When was the last time that the coastal communities were threatened by an approaching tidal wave?
(B) How far below sea level would the stations be located?
(C) Would there be enough time after receiving warning of an approaching tidal wave for communities to evacuate safely?
(D) How soon after a tidal wave hits land is it safe for evacuees to return to their communities?
(E) Can the stations be equipped to collect and relay information about phenomena other than tidal waves caused by earthquakes?

Answers

Answer:  JUST MAKE SURE TO CHANGE SOME WORDS AROUND SO YOU DO NOT GET IN TROUBLE GOR PLAGIARISM

(A) When was the last time that the coastal communities were threatened by an approaching tidal wave?

(8) How far below sea level would the stations be located?

The station is not the point at issue: we care about of people NOT stations where they are located. OUT

(C) Would there be enough time after receiving warning of an approaching tidal wave for communities to evacuate safely?

This is our answer. People have enough time or not: yes a lots of people could be saved, otherwise a lots of people could be killed

explain how a CONTINENTAL climate affects humans

Answers

Answer:

Explanation:

Floods: Climate change tends to make wet areas wetter and dry areas drier, and so there will be an increase in both flooding and droughts. Flooding is one of the most common natural disasters. Floods displace people from their homes, damage and destroy infrastructure and buildings, and take a toll on an economic level. In 2011 alone, 112 million people worldwide were affected by floods, and 3140 people were killed.

Drought: Unlike a flood, drought is rarely a direct killer. But extremely dry conditions that last for months or years can lead to food and water shortages and rising food prices, which can contribute to conflict. Droughts also have huge economic costs, even in developed countries. New Zealand, for instance, lost more than $3 billion from 2007-2009 because of reduced farm output from drought.

Fire: Increased heat increases fire risk, and climate change is expected to bring more wildfires. The current California drought, for instance, has raised the risk of “explosive” wildfires. And it’s not just burns and injuries from the fire that are the problems. “Smoke from forest fires has been linked…with increased mortality and morbidity,” the IPCC authors write in Chapter 11, “Human Health: Impacts, Adaptation, and Co-Benefits” [pdf].

Crop declines and food shortages: Extreme weather events, such as floods and droughts, will lead to declines in some crops in some areas. While this might be an inconvenience for people in developed countries when it comes to foods like limes and avocados, the situation will be far more dire when it comes to crops like corn and wheat and in countries that already struggle to feed their populations. Food shortages and increases in food prices, which increase the number of malnourished people, are a particular concern in those places that already suffering from food insecurity, such as large portions of Africa.

Heat waves: Extreme heat can be deadly, particularly among the poor who may not have the luxury of retreating to air-conditioned rooms. In Australia, for example, the number of dangerously hot days is expected to rise from its current average of four to six days per year to 33 to 45 by 2070. That will translate to more deaths: About 500 people died because of heat in Australian cities in 2011

Jameson lives in a city on the shores of the Atlantic Ocean. The temperature fluctuations are relatively small in his city because(blank)takes longer to heat up and cool down due to its high(blank) . First blank choices are: water, land, air Second blank choices are :volume, density, specific heat

Answers

Hey there! I'm happy to help!

We are looking for something that takes a long time to heat up due to a certain property, therefore affecting the weather.

FIRST BLANK CHOICE

The temperature of the land is a result, of the weather, not a cause, so this is not the correct option.

The temperature of the water does not really affect the weather. If the water in your city is cold instead of hot that will not cause the weather to be much different.

However, air is what mainly causes the weather. Air pressure fluctuations can cause certain storms and air is the driving factor of weather. Therefore, the first answer is air.

SECOND BLANK CHOICE

One of the options is specific heat. The actual fill in the blank is that is is harder for the air to heat up because of _______. Putting heat in there makes no sense. It's harder for the air to heat up because of specific heat? This is not the right choice.

The volume of the air is how much space it takes up, and air is basically everywhere, so this is not the correct choice.

The last option is density, or how thick the air is, usually due to how much water there is. This makes sense because if it is very thick you have to have more heat to get through all of the density. It would take longer to warm up a car filled with 20 people than with one person. Therefore, the second option is density.

Have a wonderful day! :D

Answer:

I believe it could be (water & specific heat) let me know if this is correct pls:)
