  2. __________ _____ What is your mass in kilograms?
  3. ______________ What is your Body Mass Index?
  4. ______________ Are you overmassive?
  5. The first graph shows data gathered by a student in SC 130 physical science.
    Soap density background rectangle major grid lines axes x-axis and y-axis linear regression line data points as circles text layers Soap density volume (cm3) mass (g) y-axis labels 0 12 24 36 48 60 72 84 96 108 120 x-axis labels 0 10 20 30 40 50 60 70 80 90 100
    __________ Calculate the slope of the line for the first graph.
  6. __________ _____ What is the density ρ of the soap (include units!)?
  7. ______________ Will the soap float or sink?
  8. __________ _____ A student measures a bar of soap with a length of 5 cm, a width of 3 cm, and a height of 2 cm. What is the volume of the soap?
  9. __________ _____ A student measures a bar of soap with a length of 5 cm, a width of 3 cm, and a height of 2 cm. The soap has a mass of 36 grams. What is the density of the soap?
  10. ____________________ A student measures the length of a piece of soap using a ruler. Is the measurement a primary or calculated measurement?
  11. __________ _____ A bar of soap is found to have a density of 1.6 g/cm³. If the volume of the soap is 100 cm³, what is the mass of the soap?
  12. In laboratory 012 the bar of soap was predicted to float or sink. When the prediction was tested by puttng the bar of soap into water, the bar of soap somehow knew what to do. Why do you think the bar of soap knew what to do?
  13. Rolling marbles background rectangle major grid lines axes x-axis and y-axis linear regression line linear regression line linear regression line linear regression line data points as circles data points as rectangles data points as diamonds data points as triangles text layers Rolling marbles Time (s) Distance (cm) y-axis labels 0 20 40 60 80 100 120 140 160 180 200 x-axis labels 0.0 1.0 2.0 3.0 4.0 5.0 A B C D The graph shows the time versus distance data gathered for four different marble speeds in laboratory 02.

    __________ _____ Determine the velocity ѵ of marble A.
  14. __________ _____ Determine the velocity ѵ of marble B.
  15. __________ _____ Determine the velocity ѵ of marble C.
  16. __________ _____ Determine the velocity ѵ of marble D.
  17. __________ _____ Calculate the velocity ѵ of a marble that rolls 280 centimeters in 4 seconds.
  18. __________ _____ Calculate the distance a marble with a velocity ѵ of 50 cm/s will roll in 8 seconds.
  19. __________ _____ Calculate the time for a marble with a velocity ѵ of 50 cm/s to roll 500 centimeters.
  20. As seen in the image, three identical vials have equal amounts of a green liquid. Based on what you learned from the soap, how would you explain that two are floating while one has sunk to the bottom?

slope m= (y2−y1) (x2−x1)
Volume V = length l × width w × height h
mass m = density ρ × Volume V
ρ= m V
distance d = velocity ѵ × time t
ѵ= Δd Δt
