An experiment was conducted to determine the density of a rock sample. The table shows a partial record of the experiment.

Experimental Record
Mass of Rock
86.5 g
Volume of Water in the Graduated Cylinder 142.5 mL

What information should be recorded in the last row of the table?

A. Ratio of the gravitational pull on the rock to the mass of the rock

B. Ratio of the volume of the water to the mass of the rock

C. Time taken for the rock to roll down an inclined plane

D. Volume of water with the rock immersed in it

Mike and mitchell decide to have a foot race. they mark off a stretch of 100 yards, and recruit cindy to work the stopwatch. after running the race and looking at the results, cindy declared that mitchell was the fastest. so how did the boys times compare?

Define the kinetic molecular theory

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
