A cyclist turns a corner with a radius of 50m at a speed of 10m/s. What is the cyclist's acceleration?

Answer:

2 m/s^2

Explanation:

a = v^2/r

a = (10m/s)^2 / 50m

a = 2 m/s^2

A cyclist turns a corner with a radius of 50m at a speed of 10m/s.  The cyclist's acceleration is  2 m/s².

The rate at which an item changes its velocity is known as acceleration, a vector quantity. If an object's velocity is changing, it is acceleration. The net acceleration that objects get as a result of the combined action of gravity and centrifugal force is known as the Earth's gravity, or g. It is a vector quantity whose strength or magnitude is determined by the norm and whose direction correlates with a plumb bob.

a = v²/r

a = (10m/s)² / 50m

a = 2 m/s²

Calculate the change in the kinetic energy (KE) of the bottle when the mass is increased. Use the formula
KE = one half.mv2, where m is the mass and v is the speed (velocity). Assume that the speed of the soda bottle falling from a height of
0.8 m will be 4 m/s, and use this speed for each calculation.

Record your calculations in Table A of your Student Guide.

When the mass of the bottle is 0.125 kg, the KE is
kg m2/s2.

When the mass of the bottle is 0.250 kg, the KE is
kg m2/s2.

When the mass of the bottle is 0.375 kg, the KE is
kg m2/s2.

When the mass of the bottle is 0.500 kg, the KE is

kg m2/s2.

You will need a magnifying glass and a small piece of scrap paper for this demonstration.

a. Go outside on a sunny day and put the piece of paper on a patch of asphalt, concrete, or a large flat rock. Make sure there is no other combustible material or debris in the vicinity.

b. Hold the magnifying glass so it is close to the paper, with rays of sunlight shining through it. Move the magnifying glass side to side and close or away from the paper until the most concentrated ray of light is shining on the paper. This is the focal point for that magnifying glass.

c. Measure the distance between the focal point and magnifying glass. This is the focal length for that magnifying glass. (Be careful; if you hold the magnifying glass in that place for long enough, the paper will catch fire. Do not ever do this on your skin or clothing, as it can cause serious burns.)

d. Now take the magnifying glass inside and use it to look at the words in a book. What is the focal length now?

Another class received similar data to what we saw yesterday. Their investigation found that it looks like water enters a plant through the roots and exits through the leaves when light shines on it. Below are three students’ claims to answer the question “what happens to the water inside the plant?”

They have collected the same evidence as our class. Using the things we have done in class so far, provide written feedback to each student. Your feedback should identify what evidence could be used to support their claim. How does the evidence you have in your Thinking Deeper Documents, support (or not support) their claims? Think of ALL the things we’ve done so far in this unit and ALL of the videos we’ve seen.

Student A: The same water molecules that come into the plant through the roots go out of the plant through the leaves. They just flow through the plant without changing.

What evidence supports students A’s claim?

Do you agree or disagree with student A? Why or why not?


Student B: The water molecules that go into the plant are used to make food molecules, and other chemical reactions in the plant form water molecules that come out of the leaves.

What evidence supports students B’s claim?


Do you agree or disagree with student B? Why or why not?

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?
