The best example of a simplifying abstraction provided by the operating system in the options you've listed is:

**Ability to access files from the shell.**

This abstraction allows users to interact with the file system in a more straightforward way, as the operating system manages the complexities of file storage and retrieval, allowing users to focus on higher-level tasks rather than the details of how files are stored physically.

The best example of a simplifying abstraction from the options provided is:

**Operating system.**

The operating system serves as a layer between the hardware and the user applications, abstracting the complexities of the hardware and providing a simplified interface for users to interact with system resources, manage files, and execute applications.

The true statement about simplifying abstractions is:

**Simplifying abstractions decreases the complexity of user interactions.**

Simplifying abstractions help users interact with complex systems in a more manageable way, making it easier for them to perform tasks without needing to understand the underlying complexities.

The most appropriate response to why it is useful to understand abstractions is:

**It allows for better debugging of a system.**

Understanding abstractions helps developers and users identify issues in a system more effectively, as they can focus on higher-level concepts rather than getting lost in the complexities of the underlying implementation.

A ball is dropped from a certain height and bounces back up. Considering Newton's Laws, which of the following best explains why the ball doesn't return to its original height?(2 points)

Responses

The First Law, because the ball remains at rest after hitting the ground.
The First Law, because the ball remains at rest after hitting the ground.

The Second Law, because some energy is lost due to friction and air resistance after the force pushes it back up.
The Second Law, because some energy is lost due to friction and air resistance after the force pushes it back up.

The Third Law, because the ground exerts a weaker force on the ball than the ball does on the ground.
The Third Law, because the ground exerts a weaker force on the ball than the ball does on the ground.

None of the above, because there is an equal and opposite reaction, so the ball must return to its original height.

The best explanation for why the ball doesn't return to its original height is:

**The Second Law, because some energy is lost due to friction and air resistance after the force pushes it back up.**

When the ball hits the ground, not all of the initial gravitational potential energy is converted back into kinetic energy for the upward bounce; some energy is lost due to factors like friction with the ground and air resistance. This loss of energy is what prevents the ball from reaching its original height.

A swimmer pushes against the water to move forward. Which of the following best describes the forces involved according to Newton's Third Law?(2 points)

Responses

The water pushes back on the swimmer with less force.
The water pushes back on the swimmer with less force.

The swimmer's push and the water's push cancel each other out.
The swimmer's push and the water's push cancel each other out.

The swimmer moves because the force from the water is greater.
The swimmer moves because the force from the water is greater.

The water pushes back on the swimmer with an equal and opposite force.

The best description of the forces involved according to Newton's Third Law is:

**The water pushes back on the swimmer with an equal and opposite force.**

According to Newton's Third Law, for every action, there is an equal and opposite reaction. When the swimmer pushes against the water, the water exerts an equal and opposite force back on the swimmer, which results in the swimmer moving forward.
