Create a claim about how kinetic energy and potential energy can change as a ball rolls down a set of steps. Describe the evidence that supports the claim from part (a).

Answers

Answer 1

Claim: As a ball rolls down a set of steps, its kinetic energy increases while its potential energy decreases.

Evidence:

This claim can be supported by the Law of Conservation of Energy, which states that energy cannot be created or destroyed, but can only be transferred from one form to another.

As the ball rolls down the steps, its potential energy is converted into kinetic energy, resulting in a net decrease in potential energy and an increase in kinetic energy.

This can be observed by tracking the ball’s speed as it descends the steps. As the ball reaches the bottom of the steps, its speed will be greater than when it started, indicating an increase in kinetic energy.

Answer 2
As a ball rolls down a set of steps, its potential energy is converted into kinetic energy. This is evidenced by the fact that as the ball descends, its speed increases, which is a result of the conversion of potential energy (stored energy due to its position) into kinetic energy (energy of motion). The height of the steps determines the amount of potential energy the ball has at the top, and the mass of the ball determines how much kinetic energy it gains as it rolls down. The conservation of energy principle states that the total energy of a system remains constant, so the potential energy lost by the ball is equal to the kinetic energy gained. Therefore, as the ball rolls down the steps, its potential energy decreases while its kinetic energy increases. HOPE THIS HELPS!!

Which of the following interacts the most with the water cycle?

A. Global wind and rain
B. The sun and rivers
C. Precipitation and Groundwater

Answers

Answer:
The correct answer is C

Explanation:

Precipitation is the key driver of the water cycle, as it is the source of all water on the planet. Groundwater is the water that exists below the ground, and it is an important component of the water cycle. The interaction between precipitation and groundwater is a crucial part of the water cycle, as groundwater reserves serve as a buffer for times when little precipitation is falling, like during prolonged droughts.

describe the energy of the weight when its A)pulled back the furthest extent, B)at the bottom of the swing, C)at the highest point on the other side, and D) back at the original side

Answers

Answer and Explanation:
A) When the weight is pulled back to its furthest extent, the weight has the highest potential energy. This is because at this point, the weight is furthest away from the center of the earth, and so the potential energy due to gravity is maximized.

B) At the bottom of the swing, the weight has the lowest potential energy. This is because at this point, the weight is closest to the center of the earth, and so the potential energy due to gravity is minimized.

C) When the weight is at its highest point on the other side of the swing, the weight has the highest kinetic energy. This is because at this point, the weight has the highest velocity, and kinetic energy is proportional to the square of the velocity.

D) When the weight is back at its original side, the weight has zero kinetic energy. This is because at this point, the weight has come to a stop and is no longer moving. However, the weight still has a non-zero potential energy due to the force of gravity.

Answer:

Explanation:

Example ,The energy of a pendulum weight changes as it swings.

Here answers and explanations

A)When the weight is pulled back to the furthest extent, it has maximum potential energy and zero kinetic energy.

B)At the bottom of the swing, the weight has maximum kinetic energy and zero potential energy.

C)When the weight reaches the highest point on the other side, it has maximum potential energy and zero kinetic energy again.

D)As the weight swings back to the original side, it has the same energy as it did at the beginning, with some potential energy and some kinetic energy. Although the weight loses some energy due to friction and air resistance, its total energy should be conserved throughout the swing.

a women runs 1 kilometers (1000 meters) with a force 210, and an output power of 500. how long does it take her to run 2 kilometers (2000 meters)?

Answers

Explanation:

woman runs a kilometer using a force of 210 N and a power output of 500 W. How long in minutes does it take this woman to complete 1 kilometer?

Beginning of dialog window. Escape will cancel and close the window. End of dialog window. Finally, we need to convert seconds to minutes: Time = 420 s × (1 min / 60 s) = 7 min So, it takes the woman 7 minutes to complete 1 kilometer.

Read this excerpt from a passage. "Schools also censor by prohibiting some articles to be printed in student newspapers. Approximately 74 percent of high schools in the United States offer student newspapers or journalism programs (Barron, 2010). Student publications are a safe venue where adolescents can express their opinions. These programs are often run by students and overseen by teachers and other adults at the school. Before articles are printed, they usually go through an editing and review process. Although this is a normal part of the publication process, it can sometimes lead to censorship. There have been many cases where portions of the text or entire articles have been removed from school newspapers for being inappropriate. A famous Supreme Court case involving this issue occurred in 1988 in Hazelwood v. Kuhlmeier. The principal of Hazelwood East High School prohibited two topics from being printed in the school newspaper. Hazelwood East students brought the case to court, arguing that their First Amendment right to free speech had been violated. In this case, the court ruled that the principal did not violate the students free speech right. The court pointed out that the school newspaper was not a 'public forum,' and that, therefore, students did not have the same First Amendment rights as other journalists (Student Press Law Center, 2014). Many people were outraged by this decision and continue to fight censorship in school newspapers." Which of the sources from these references entries contains the information about the Hazelwood v.
