Our understanding of the atom has changed over time. Which idea that was once accepted is now considered scientifically
inaccurate?

A. Electrons are arranged in layers.

B. An atom is a solid sphere.

C. The nucleus is the center of the atom.

D. Electrons have a negative charge.

Answers

Answer 1

Answer:

B. An atom is a solid sphere

Explanation:

The idea that the atom was a solid sphere paved back to the first atomic model in the 19th century theorized by John Dalton. According to him, an atom is intact and hard and cannot be broken down or divided.

However, many scientists continued to research and it was found that the atom was not actually a solid sphere. It was made up of protons (positively-charged), electrons (negatively-charged) and neutrons (neutrally-charged). This invalidated Dalton's solid sphere model.

16. How do you calculate specific gravity (how we describe the density of mineral samples)?

Answers

To determine the specific gravity of our sample, we simply divide the mass of the sample (that is, 150 grams) by the mass of the same volume of water, which would be 20 grams. So, specific gravity = 150 grams of the sample / 20 grams of water. Specific gravity = 7.5. ... For example, quartz has a specific gravity of 2.65.

Separated from the rest of Europe by

developed today because they missed the
A. Reformation
B. Industrial Revolution
C. Glorious Revolution
D. First World War

Answers

The answer is B. The rippling affects of them missing out of industrializing went all the way to the early 2000s. During the 80s they were a third world country. This only worsened because of the Spanish civil war in which the nationalists won but at a cost and Francisco Franco as a fascist dictator all the way till the 70s. Portugal was the once former colonizer and with small space on Europe, they fell under the bus of industrialization. Civil wars or wars in general or missing out on catching up with the rest of Europe has happened to many other countries, some examples are Italy when it took a series of wars to unite it and it tried industrializing but not as much as the U.K, Germany, or France. Other victims are Serbia, Bosgnia, Croatia, Albania, Greece, Romania, Bulgaria, Montenegro, and Moldova. These countries are underdeveloped was because the hundreds of wars between the Austrian/Hungarian empire and the Ottomans, and then came the two world wars, and to sure up their fate, the Soviet Union occupied them and starved their population and repressed any form of protest or means of change. I hope that explains it.

Why is the motion of the water in the bin considered a cycle? What could stop the cycle? What could accelerate it? can someone help plz <3

Answers

When this vapor hits cooler air it changes back to its liquid form and creates clouds. When so much of the water vapor has condensed and the clouds are heavy, the liquid falls back down in the form of precipitation.

As water on earth moves in a cyclic form, it is recycled and remade through various processes.

In order to know the motion of the water in the bin, we must know the process of evaporation, condensation, and precipitation  

The water that continues to fall back in the form of snow, rain, or hail is again taken up in a  cyclic process the next day. The cycle works through the solar heating mechanism. Rising in temperature, increase in salinity can lead to acceleration, and condensation or cooling down can stop the cycle.

Hence as water cycles form the oceans to atmosphere it moves in an endless cycle.

why did the rulers of spain want a shorter route to the east indies

Explanation:

The rulers of Spain want a shorter route to the east indies for the sake of the economy and to make receiving the priceless spices quicker and simpler, they desired speedier trading routes.

What were the trade routes for Spain?

The first European countries to build global trading empires were Spain and Portugal. By treaty (Tordesillas, 1494; Zaragoza, 1529), Spain claimed the majority of the Americas. After crossing the Pacific, the Spanish trade route continued on across the United States, passing over the land bridge that connects ports like Acapulco and Veracruz.

The wealth amassed along South America's west coast also travelled via Colon over the Panama Canal. On its journey to Europe, a sizable quantity of wealth was therefore passing via the Caribbean. For the Portuguese, the trade route had to go around the Cape of Good Hope rather than through a land bridge.

Answers

Answer:

When the temperature is significantly warmer in the northern part of North America, a Southern Oscillation is taking place.

Explanation:

One very curious but very influential occurrences when it comes to weather conditions is the Southern Oscillation. It is not something that happens regularly, but instead, it can happen on two years distance, 5-year distance, or anything in between. What happens basically is an intense warming up of a huge area of the eastern part of the Pacific Ocean.

The warming up of a large part of the largest ocean in the world influences the weather conditions all over the planet, though in some regions like the ones that are around the Pacific it has a big influence, in the regions that are further away it has much smaller influence. Some areas get long and hot droughts, some places experience heavy rainfall for a long period of time, while some places, like the northern part of North America, experiences unusually high temperatures for its latitude.

3. Judaism was completely removed from Europe
4. The Catholic Church and Protestant Churches reunified into one

Answers

Correct answer is 2. The percentage of Christians dropped from 95% to 70% .

Explanation:

First option is not correct as Islam wasn't majority in religion in Europe. Protestants, Catholic and Orthodox were and are still majority.

Second option is correct mostly due to fact that many communist regimes were established and the number of believers lowered.

Third option is not correct as although many Jews were killed during WW2, and some left Europe, there are still some who were living mostly in Eastern Europe.

Fourth option is not correct as these two churches never reunited since they were separated in 16th Century.
