If you are travelling in a spaceship travelling with speed comparable to speed of light, then to a stationary person outside the spaceship, time appears to slow down in the spaceship. What would appear to a person (you) when you are looking out of the spaceship at the stationary world? Will time of the outside stationary world even slow down for the person moving with speed comparable to speed of light?

For my Human Physiology/Lab Honors class, we performed an experiment in which iodine was placed on the hands and the arms and covered by a piece of paper for thirty-five minutes. Following this time, my partner and I discovered that the iodine on her palms had collected onto the sheet of paper covering it, but that the iodine on her arms had not stained the piece of paper covering it. We believe that the dermal papillae located on the palms may have caused the iodine to collect in her palms more than on her arms, but what in the composition of paper would have caused the iodine to be attracted to the paper?

I reallly enjoyed earth science when i was in high school. I am now considering a major in college. I was thinking geology but realized that was more the study of earth, where as in my earth science class we studied space too. Is there a major that covers both?

4.20 g of a hydrocarbon, C20H16, were burned in excess oxygen in a constant-volume calorimeter surrounded by 1250. g of water. As a result the temperature of the water and the calorimeter rose from 21.3 oC to 26.1 oC. The heat capacity of the calorimeter was 251.040 J/oC.





Calculate DE (kJ/mol) for the combustion of the hydrocarbon based on these readings.
