An electric device delivers a current of [tex]$15.0 A$[/tex] for 30 seconds. How many electrons flow through it?
Answer (2)
The service described in the question is AWS CodeBuild . AWS CodeBuild is a fully managed continuous integration service provided by Amazon Web Services.
Here's a breakdown of what AWS CodeBuild does and why it's the correct choice:
What AWS CodeBuild Does:
Compilation of Source Code: CodeBuild automatically compiles your source code according to the build specifications you provide. This means you don't have to manually set up, configure, or maintain build servers.
Running Tests: After compiling the code, CodeBuild can run automated tests to ensure that the software functions as expected.
Producing Software Packages: CodeBuild produces ready-to-deploy software packages, helping streamline the development and deployment process.
Why It's the Correct Choice:
AWS CodeBuild specifically focuses on building code, which is a critical part of the continuous integration process. The primary objective of CodeBuild is to take your source code and convert it into build artifacts.
How It Works:
Integration: CodeBuild integrates with a variety of source control systems, like AWS CodeCommit, GitHub, or Bitbucket.
Automatic Scaling: It scales automatically to meet your build needs, so you only pay for the compute resources you use.
Comparing with Other Options:
AWS CodeDeploy (A): Used for deploying applications to a variety of services.
AWS CodePipeline (B): Orchestrates the entire continuous delivery process, including build, test, and deploy.
AWS CodeCommit (D): A source control service for hosting Git repositories.
Each of these services focuses on different stages of software development and deployment, but AWS CodeBuild is the one specifically designed for building and testing code.
The correct choice is (C) AWS CodeBuild.
For a current of 15.0 A for 30 seconds, the total charge is 450 C. This corresponds to approximately 2.81 x 10^21 electrons flowing through the device. This is calculated using the charge of a single electron (1.6 x 10^-19 C).
