Which statements can be supported by using a position-time graph? Select three options.
A negative slope results when an individual is moving toward the origin.
A horizontal 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 origin.
The slope of the line gives the velocity of the individual.
The speed of an individual cannot be determined from this type of graph.

A, C, and D

- 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.

- The slope of the line gives the velocity of the individual.

the components of a vector are the parts of the vectors that are to each other.

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
