does a atom power a star

Answer: yes

Explanation: All atoms larger than hydrogen and helium have been made within the thermonuclear furnace of a star, powered by nuclear fusion. This is the process in which smaller atoms, i.e., hydrogen and helium, are smashed together to form larger elements, such as carbon.

if a marble took 1.63 seconds to go the first 50cm's, and 1.89 seconds to go the second 50cm's, and then 2.69 seconds to go the whole 100cm's, what was the average velocity and acceleration for the marble?

Extra info: The table was tilted 20 degrees upwards


Please answer an real answer and not a bunch of random words or letters, or I will report you. Thank you! <3

Scientists often use containers to hold chemicals. A beaker can hold solids or liquids that won’t release gas and are unlikely to splatter if stirred or heated. A test tube is basically a smaller version of a beaker. It can hold small amounts of chemicals. If you’re worried about a substance splattering, an Erlenmeyer flask might be a good tool to use. Erlenmeyer flasks have a triangular shape to minimize splattering and spilling. To be extra safe about spills, you might use a stopper. However, never heat a container with a stopper on it!

According to the passage, why is a substance in an Erlenmeyer flask less likely to spill than a substance in a beaker?

A
because Erlenmeyer flasks can never be heated

B
because Erlenmeyer flasks can only hold solid substances

C
because Erlenmeyer flasks hold smaller amounts of substances than beakers

D
because Erlenmeyer flasks have a triangular shape

You left some papers on a picnic table in the park on a windy, sunny day. When you returned, the papers were scattered all over the park. What can you conclude about the flow of energy in this situation?

The heat energy from the sun was transformed to sound energy, which moved the papers.
The heat energy from the sun was transformed into kinetic energy, which moved the papers.
The mechanical energy in the wind was transferred to the papers, which caused the papers to move.
The mechanical energy in the wind was transferred to the table, which caused it to shake and move the papers.

How do we know there has not been an increase in the number of earthquakes? Officials from the U.S. Geological Survey, the government agency that keeps track of earthquakes, point to statistics. On average, there have been no more earthquakes so far in 2010 than there were in previous years.

What Happens During Earthquakes?

In reality, it's not the number of quakes that has gained our attention, but the devastating impact quakes can have. Earthquakes are very natural—it's inevitable that they'll happen because of the way the planet works. The earth's surface is made up of tectonic plates that fit together like puzzle pieces and are always moving past each other. When two of the plates' edges get caught, stress builds up at the fault line—the crack between the plates. When the plates are finally able to break free of each other, the stress is released, and an earthquake occurs. Earthquakes of varying strengths happen every day, usually at fault lines. Some of these quakes have a high magnitude, while others are relatively weak. But it's often where an earthquake takes place that determines whether it will be something that goes largely unnoticed, or a disaster that affects thousands of people.

What Is Changing?

In the past, earthquakes were not as much of a problem because Earth's population was smaller, and cities were less populated.

"Look at some of the big [earthquakes] recently," said Debarati Guha-Sapir of the World Health Organization. Guha-Sapir cited some earthquakes that took place in areas where the population had increased in recent years, making the quakes more serious. "Had the Izmit or Bhuj quakes [of 1999 and 2001] happened 30 years ago, the events would have been relatively insignificant, as the [populations] of these cities were a third of what [they were when the earthquakes happened]. Increasing population density makes a small event into a big one."

Some of the earthquakes that took place in early 2010 occurred in highly populated areas, as well. More people are moving into megacities that happen to be built on fault lines—and many cities are on fault lines. Of the 130 cities with more than one million people, more than half are in earthquake zones, making them more prone to earthquakes.

In many of these cities, officials have drawn up laws requiring that buildings be designed and constructed to endure earthquakes. But some cities, particularly those in developing countries, lack the resources to do this. There, people are rapidly putting up substandard buildings that can't withstand the force of the shaking earth. For example, the Haiti earthquake took place near the nation's crowded capital. There was a great deal of destruction because there were "too many people crammed into a city that wasn't meant to have that many people and have an earthquake," said University of Miami geologist Tim Dixon.

Another reason quakes seem worse is that we're paying more attention. Everyone noticed when the Haiti earthquake was quickly followed by the Chile earthquake. Many people watched the news and the Internet for updates on these disasters, unable to believe that they were seeing two major earthquakes in such a short period of time. But eventually, the earth will have a period when earthquakes are minor or in unpopulated areas. Then people won't notice quite so much anymore.

"People are paying attention to the violent planet we've always lived in," said Dennis Mileti, a seismic researcher. "Come back [at a time when] there have been no [noticeable] earthquakes, [and] most people will have forgotten [about them] again."

According to the article, what is one reason why it seems as if the world is experiencing more earthquakes than usual?
