Question
1. If the smallest increment on a ruler is 0.01cm, to how many decimal places should measurements be recorded? 2. Name two major points to watch out for when selecting a scale for the graph other than making sure none of the data points are excluded. 3. If the equation of a line is given as y 7.8x+1.9, what is the slope and y-intercept of this line? If the y-intercept of a line is 2.31 and the slope is 0.825, what is the equation of this line? The following are the coordinates of two points that lie on a line. (s stands for seconds.) 4. 5. (15.8 s, 78.3 cm) and (29.1 s, 94.2 cm) What is the slope of the line? Show your calculation setup. Include units in your setup and in your answerExplanation / Answer
Ans 1 :
The measurement is always recorded at one place more than the smallest increment on the scale.
Since here the smallest increment on the ruler is 0.01cm , which has 2 decimal places , the measurement will be recorded to 3 decimal places.
