Which statements can be supported by using a position time graph? select 3 correct choices
a negative slope results when an individual is moving toward the origin
ahorizontal line on the graph means the individual is moving at the same velocity
a positive slope results when an individual is moving away from the ongin
the slope of the line gives the velocity of the individual
the speed of an individual cannot be determined from this type of graph

The correct answers are: "A negative slope results when an individual is moving toward the origin", "A positive slope results when an individual is moving away from the origin", and "The slope of the line gives the velocity of the individual".

Explanation:

A position time graph is a representation of a motion of an object, constructed by comparing the position (using units of distance) against the time (using units of time). A position time graph allows to measure how far an object has traveled according to a certain period of time. In a position time graph, the slope of the line represents the velocity of the individual since it represents a distance over time measurement. A positive slope results when an individual is moving away from the origin, since more distance has traveled as time passes. Conversely, a negative slope results when an individual is moving toward the origin

characterization of nanoparticles is a critical step in nanomaterial production as it provides information of dimension, morphology, surface charge, distribution and degree of surface functionalization.

the answer is b.) hydrogen bonds between bases.
