Two students were conducting an experiment. Each student had a test tube filled with 25.0 mL of a clear liquid. The students drop a penny into each test tube
and measure the rate at which the penny falls. The students' data is shown below:
Test tube A
Test tube B
Time to reach the bottom of the test tube
10.0 sec
40 sec
Which test tube contains the substance that is more viscous?
A. Test tube A, because it took a shorter time to reach the bottom of the test tube.
OB. Test tube B, because it took a shorter time to reach the bottom of the test tube.
C. Test tube A, because it took a longer time to reach the bottom of the test tube.
OD. Test tube B, because it took a longer time to reach the bottom of the test tube.
