The answer is a 3D Printer
Answer:
Hello there! There are 4 parts to this question, all regarding relational database concepts.
Explanation:
Parts 1, 2, 3, 4 are drawn in attachments. For Part 4, the "foreign keys" would be the id fields of the joining table, and the "primary keys" are the IDs of the table itself. Data types are "integer" for ID, "string" for text columns like Name and Location, and "Decimal" for Hourly rate in the Timesheet table. Note that we can further simplify the erd from the one constructed earlier in part 3 to remove the Project Manager model and instead add a Project Manager "boolean" flag in the Employee table since a Project Manager is also an Employee.

Answer:
b. This would set the group ownership of file1 to root.
Explanation:
Linux allows user to have his own files and regulate the ability of other users to access them. The <em>chown</em> command allows you to use the appropriate utility to change the owner of a file or directory.
The basic command syntax is as follows:
# chown [options] <owner name: owner group name> <file or directory name>
For example, if you want to give a user <em>root</em> opportunity to use the <em>file1.txt</em> file as he wishes, you can use the following command:
# chown root file1.txt
In addition to changing the owner of a file, the group of its owners or both can be changed at the same time. Use a colon to separate the username and user group name (without the space character):
# chown user2:group2 file1.txt
As a result, the user with the name <em>user2</em> will become the owner of the <em>file1.txt</em> and its group will become <em>group2</em>.
In your case omitting username
# chown :root file1.txt
will change owner group only.
