Nuetrik [128]

Answer

0.9516 grams / mL (50.00 has 4 sig digs.)

Remark

You have a couple of extraneous numbers there. You don't care about anything except the mass of the flask +  water/alcohol mixture  (88.219 grams). and the mass of the flask (40.638 grams)

Formulas

  • mass water/alcohol mixture = mass of the flask with fluid - mass flask
  • density = mass / volume

Solution

mass water/alcohol mixture = 88.219 - 40.638 = 47.581

  • Volume = 50 mL
  • Density = mass / Volume
  • Density = 47.581/50
  • Density = 0.95162  There are 4 sig digs so the answer should be

Position (m)
Alex777 [14]

Option C. The object is returning to the start at a constant speed.

<h3>Data points of the Position vs Time graph</h3>

The following data points will be used to determine the motion of the object.

<u>Position               Time</u>

12                          4

10                          6

2                            8

0                           10

From the data above, the position of the object is decreasing towards zero or start point.

Thus, the object is returning to the start at a constant speed.
