The mass of the puck is
m = 0.15 kg.
The diameter of the puck is 0.076 m, therefore its radius is
r = 0.076/2 = 0.038 m
The sliding speed is
v = 0.5 m/s
The angular velocity is
ω = 8.4 rad/s
The rotational moment of inertia of the puck is
I = (mr²)/2
= 0.5*(0.15 kg)*(0.038 m)²
= 1.083 x 10⁻⁴ kg-m²
The kinetic energy of the puck is the sum of the translational and rotational kinetic energy.
The translational KE is
KE₁ = (1/2)*m*v²
= 0.5*(0.15 kg)*(0.5 m/s)²
= 0.0187 j
The rotational KE is
KE₂ = (1/2)*I*ω²
= 0.5*(1.083 x 10⁻⁴ kg-m²)*(8.4 rad/s)²
= 0.0038 J
The total KE is
KE = 0.0187 + 0.0038 = 0.0226 J
Answer: 0.0226 J

What should you do when a garbage can is nearly full.
Answer:
You can also place a false bottom inside the trash can to stop overfilling. To do that, simply place an object like a cardboard box underneath and outside the bag so that when it appears full it will not be as heavy as a bag that reached all the way to the bottom.
Explanation:
(winks and runs off)
When the garbage can is full, it is transferred into bigger dustbins that are placed outside the houses.
What is garbage management?Domestic composting, recycling, reusing, and burning or burying of waste in their own yards are all examples of on-site household waste management. Off-site household waste management consists of delivering separated recyclables to drop-off locations, dumping at a landfill or in public trash cans, or making donations.
The environment is protected from the hazardous effects of the inorganic and biodegradable elements included in trash via waste management. Air pollution, soil erosion, and water poisoning can all result from improper waste management. If waste is collected and managed well, it can be recycled.
Therefore, when the trash container is full, it is moved into larger trash containers that are positioned outside the homes.

What scientific innovation occurred that affected the art that was produced during this period? a. Albert Einstein’s Theory of Relativity b. The invention of the phonograph c. The polio vaccine was first developed d. Penicillin was discovered Please select the best answer from the choices provided A B C D.
Answer:
aaaaaaaaaaaaaaaaaaaaaaaaaa it a
Explanation:
Albert Einstein’s Theory of Relativity is the scientific innovation occurred that affected the art that was produced during this period. The correct option is A.
What is Albert Einstein’s Theory of Relativity?Albert Einstein's Theory of Relativity is a set of two interrelated theories that fundamentally changed our understanding of space, time, and gravity. The first theory, called Special Relativity, was published by Einstein in 1905 and dealt with the physics of objects moving at high speeds. The second theory, called General Relativity, was published in 1915 and extended the ideas of Special Relativity to include gravity.
Special Relativity postulates that the laws of physics are the same for all observers who are moving at a constant speed relative to one another. This means that there is no single "absolute" time or space, but rather that these concepts are relative to the observer's frame of reference. The theory also introduced the concept of time dilation, which means that time appears to slow down for objects moving at high speeds relative to a stationary observer.
General Relativity, on the other hand, describes gravity as the curvature of spacetime caused by the presence of matter and energy. In this theory, massive objects warp the fabric of spacetime, causing other objects to move along curved paths. This explains why objects orbit around each other, as well as the bending of light around massive objects.
Einstein's Theory of Relativity has had a profound impact on modern physics and our understanding of the universe. It has led to the development of new technologies such as GPS and has provided a framework for further research into the nature of the universe, including the study of black holes, the Big Bang, and the search for a unified theory of physics.
Here in the Question,
This scientific innovation, introduced in the early 20th century, revolutionized the way scientists and artists understood space, time, and the nature of reality. The concept of relativity, which challenged the traditional Newtonian worldview, had a significant impact on modern art movements such as Cubism and Futurism, which sought to depict multiple perspectives and the dynamic nature of reality. The theory also had a profound influence on the development of abstract art, which aimed to represent the invisible forces and structures that underlie the visible world.
Therefore, The best answer is A. Albert Einstein’s Theory of Relativity.

Which features do most stratovolcanoes and cinder cone volcanoes have in common?.
shield volcanoes from very large gently sloped mounds from effusive eruption
Both stratovolcanoes and cinder cone volcanoes have steep sides and violent eruptions. The correct option is B.
What is a volcano?An opening in the crust of a planet or moon known as a volcano allows molten rock, heated gases, and other things to erupt.
The steep, conical-shaped strato-volcanoes are created by the alternating ash and lava deposits. This type of volcano's magma is made up of bubbles and has a high silica concentration.
A stronger force is applied from the bottom towards the surface after the gases in these bubbles are released. As a result, they are extremely explosive and produce large-scale material eruptions. Take Mount St. Helens, for instance.
The simplest volcanoes have steep sides and are called cinder cones. They are constructed from the substances and partially hardened lava spewed from the volcano's vents.
Due to the power of the gas and the molten lava that have gathered near the vent, eruptions are frequently explosive. Consider the drug Paricutin.
Thus, the correct option is B.

The tiger's whisker questions and answers.
Answer:
Explanation:
The folktale "The Tiger´s Whisker" originates from Korea, and it is used mostly as a child´s tale. It narrates the story of Yun Ok, whose husband has changed drastically from a loving, and gentle man, to an irrascible one, thanks to the wars. In desperation, Yun Ok, goes to a hermit and asks for a potion. The man tells her that in order to do so, she must bring a whisker from a live tiger. Yun Ok does as she is told, and patiently gains the trust of a tiger, and gets the needed whisker. In the end, she finds out that the lesson the hermit wanted her to learn was that to regain her husband, she needed to apply the same technique she used on the tiger, and not a potion. Given this background, the answers would be thus:
1. A folktale is defined precisely as: A story that is often passed along by word of mouth from one generation to another. This is the correct answer.
2. In this question, the answer is: Her husband has become very distant since he returned from war. This is what is narrated in the story as the reason for Yun Ok´s husband´s estrangement.
3. The correct answer here is: He laughs at Yun Ok´s idea because he thinks she is foolish to believe that solving the problem with her husband could be so simple. Though not directly stated, the hermit does laugh in a way when he says to Yun Ok that healing her husband with a potion is not like taking care of an ear infection. And he makes her feel somewhat foolish for her request. But she insists and he gives in.
4. The answer to this question is: She decides that reconnecting with her husband is worth the risk. This is stated in the story when Yun, although afraid, still continues persistently to go after the tiger, always keeping in mind that all is for the benefit of herself and her husband.
5. The answer here is: She learns that through patience, she can win her husband´s trust and heart like she earned the trust of the tiger. This is the lesson she learns when the hermit burns the whisker and makes her reflect on how she was able to get it from a wild tiger, saying that a man cannot be fiercer, or more difficult, than a tiger.
6. The answer here is: She is patient and demonstrates perseverance by spending six long months, slowly getting the tiger to trust her before she plucks out his whisker. This is exactly what she does in the story. She spends every day of those six months, carefully gaining the tiger´s trust, until he allows her near, and then allows her to take his whisker.
