Elementary knowledge is essential and specialised. This level teaches fundamental concepts in numerous subjects.
"Elementary" or "fundamental" knowledge contains the most particular notions. This understanding creates the foundation for more complicated thoughts and numerous fields of study.
Elementary knowledge in science, mathematics, and other fields includes foundational ideas, definitions, and concepts needed to understand more complex topics. Such as:
Elementary mathematics includes basic arithmetic, number characteristics, and geometric shapes.
Elementary physics contains Newton's laws and thermodynamics.
Grammar, sentence structure, and vocabulary are elementary in language and literature.
Programming and data structures are computer science basics.
Elementary biology covers cell structure and function.
This foundational information is essential for understanding and interpreting more sophisticated ideas and theories in numerous topics. It supports field-specific learning and exploration. As a person masters basic knowledge, they can go on to more complex topics in their field.

Answer:
The average velocity is 50 km/h south
Explanation:
The average velocity of an object is its total displacement divided by
the total time taken.
That means it is the rate at which an object changes its position from
one place to another.
Average velocity is a vector quantity.
The SI unit is meters per second.
A bicycle that starts 100 km south and is 120 km south of town after
0.4 hour.
The displacement = 120 - 100 = 20 km south
The time = 0.4 hour
The average velocity = , where D is the displacement
and t is the time
The average velocity of the bicycle = km/h
The average velocity is 50 km/h south
If you want it in meter per second, change the kilometer to meter
and change the hour to seconds
1 km = 1000 m
1 hour = 60 × 60 = 3600 seconds
The average velocity of the bicycle = m/s south

Explanation:
coal burning
B.
nuclear power
C.
solar heating
Solar heating is the system composed of a fluid system to move the heat from the collector to its point of usage and a reservoir to stock the heat
Explanation:
The options given here like coal burning uses solid material as the source to heat and to generate energy. Similarly, nuclear power also requires solid particles like atoms or neutrons to strike the moderators forming energy.
In both of these cases, fluid system is present but it is used completely as coolant and to maintain the temperature. Thus, the remaining system that is solar heating has been done for water tanks where the fluid as water is used to move the heat from its collector to its point of usage. Even in solar system it is used as reservoir to stock the heat.
