how do you find the instantaneous velocity on a position vs. time graph? by drawing a horizontal line by…

Brief Explanations:

Instantaneous velocity on a position - time graph is the rate of change of position at a particular instant. The slope of a tangent line to the curve at a given point represents this rate of change. A horizontal line gives zero slope (constant position, zero velocity), measuring height gives position not velocity, and calculating area under the graph is related to displacement in some cases but not instantaneous velocity.

Answer:

B. By drawing a tangent line and finding its slope
