Answer: Data model
Explanation: Data model is the arrangement of the information in the form of table structure to maintain it in the form of database.They help in the keeping the entities in the sequence and can be tracked when required.Example- vendors records,customer record etc.
Other options are incorrect because the data retrieval is the regaining of the data from database, record instance is the parts of the database records and meta data give knowledge about other data.

Answer: Registers
Explanation:
Registers are small storage locations identified by different types of registers. The function of the register is to provide data for immediate processing to the CPU. These registers hold data temporarily and provide easy access of data to the processor.
Answer:
60 J
Explanation:
Given,
Work done to push the box = 100 J
Energy dissipated by friction = 40 J.
According to work energy theorem work done is equal to change in kinetic energy.
Change in Kinetic energy = Work done by student + Work done by friction
Change in Kinetic energy = 100 J - 40 J
Work done by the friction will be negative because it will act in opposite direction of force applied.
Change in Kinetic energy = 60 J
The tool that sets rules for both the transport of data packets and the addressing system for a network such as the ARPANET is called; Protocol
<h3>Understanding Protocols</h3>
In computer systems communications, a protocol is defined as a set of rules and regulations that allow a network of nodes to transport and receive data information.
Now, each transport layer in a system of network such as ARAPNET will always have a protocol set such as TCP and IP.
