I am pretty sure this is a demonstration. A demonstration is a method of experiment that had only been done once, while an experiment is a method that has been done repeatedly. Hope this helps!
Answer:
Explanation:
Acceleration on a VT graph is the slope of the line at the given point. We can find the slope at 3 with Δy/Δx. This gives us (4-2)/(3-(-3)) which works out to be -3m/s^2
Answer:
The correct answer is b. Differences in Path Lenght
Explanation:
In this area of knowledge, there two main ways of referring to Path Lenght:
1. The total distance an object travels from a starting point, without considering trajectory.
2. When talking about wavelength, because this relates to light and how it travels throughout different mediums. This concept is used in calculating constructive and destructive interference of waves, and is responsible for seeing different shades of tea color.

A diameter is a straight line that begins at one end of the circle and ends at the opposite end. The condition for a line to be a diameter is that it must pass through the centre of the circle. If a line that touches two points on the circle, does not pass from the centre of the circle, it cannot be called a diameter.
The length of the diameter is the measurement of the line that connects the two points of the circle.
