Ascience class tested ways to clean water after an oil spill. each group of students was given 100 ml of vegetable oil, 100 ml of engine oil, and 800 ml of water in a rectangular plastic container. each container also held five floating wooden cubes (5 cubic centimeters each) representing animals in the water. each group was tasked with removing as much oil as possible in a 20 minute period, leaving “clean water” in the container, using whatever tools they brought to class. the results of the “clean-up” are presented in the table below. group vegetable oil removed (ml) engine oil removed (ml) 1 10 20 2 110 130 3 60 40 4 80 70 based on the results above, which group’s data seem unreliable?

What is the most important factor in determining climates.

The graph indicates the running route for tobias. which best describes his run? from time 0 to 6, he went fast and then slowed down. from time 6 to 10, he was at his slowest. from time 12 to 14, he went very slow. from time 14 to 18, he went toward the starting point.

For questions 1 and 2, consider the following experimental data. hydrogen emission lines were detected at the following wavelengths (in nm): 121.6102.697.395.093.8question 1use the electromagnetic radiation classifications below and figure 1-1 in the introductory information for this lab (in the lab manual) to determine the nf value for the experimental data provided? wavelength, ?
