Explanation:
In positional number system,
1. each symbol represents different value depending on the position they occupy in a number.
2. In positional number system, each system has a value that relates to the number directly next to it. The total value of a positional number is the total of the resultant value of all positions.
3. Example: 12 can be 1 x 10 + 2 x 1, 10 + 2= 12
whereas in Non-Positional number
1. In non-positional number system, each symbol represents the same value regardless of its position
2. In non-positional number system each symbol represents a number with its own place value.
3. Example: Roman number system where I for 1, II for 2 etc.

Answer:
Number of times a cricket chirps.
Explanation:
Let us use a graph to understand the function Here the entomologist wants to know the effect of temperature on the number of chirps of a cricket so, the chirps should vary with temperature. The opposite cannot be true i.e., the temperature is not dependent on the number of chirps rather the number of chirps are dependent on temperature.
So, the x axis will be represent the temperature and the y axis will represent the number of chirps.
Hence, the dependent variable will be number of times a cricket chirps i.e., the y axis.
Answer:
The answer is It has inertia

I just got it correct on E2020
The person walking down the sidewalk follows the newton's third law of motion.
Explanation:
- A person is able to walk down the sidewalk by using the reaction forces from the ground.
- In simple term, feet pushes the ground and the reaction forces makes the feet able to walk.
- Another important force included in the walking mechanism is friction. With out friction one cannot walk down the sidewalks.
- Hence the forces involved in the walking of a person down the sidewalk are:
- Friction force
- Action and reaction force between ground and person's feet.
