Sam and Loretta saw a cool experiment on TV and wanted to try it on their own. First, they poured sand into a plastic cup until it was half full. Next, they used a thermometer to take the sand’s temperature. They then taped a cup upside down on top of the cup with sand in it. Sam and Loretta took turns shaking the cup. They shook it 100 times, un-taped it, and took the sand’s temperature. The temperature was 10 degrees C. They re-taped it, shook it 500 times, un-taped it and took the sand’s temperature. The temperature was 15 degrees C. They re-taped it, shook it 1000 times and then un-taped it and took the sand’s temperature. The temperature was 20 degrees C. 1. What was the Independent Variable for this experiment?

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.

the journeys of marquette, joliet and la salle a) new france expand.

all three of these explorers explored the midwest and the area around the great lakes, which they subsequently claimed for france.

this was a big portion of territory and expanded new france which before then only consisted of quebec province in northeastern canada
