as the light output increased. This is because to the increase of energy as heat produces light and energy. The energy allowed the glow stick particles to rapidly move and spread. 3. When the glow stick was emitted into the cold water it became dimmer as the light output decreased. This is because the cold water causes the glow stick particles to slow down thus causing the light to have a decrease in energy as energy is produced from

The famous moon landing of 1969 will never be forgotten because it was all real. There are many who believed that the original moon landing was faked or set up in a studio. People have many good reasons to believe this‚ but there are also many good reasons to believe it actually happened. People get most of their worries from the pictures took on the moon from the original landing.

by comparing the spectral lines of the elements and the spectral lines of the same elements measured in a lab. The more distant the objects that emit light the brighter the spectral lines. In 1998 scientist observed that the supernovas are becoming dimmer‚ which means they are getting closer instead of farther away. They were able to show that dark energy has an influence on light particles and photons. When a photon passes a galaxy it falls into the gravitational pull‚ and the dark energy because

posted and it is essential that drivers are aware of these changes in order to keep others safe. The vehicles have changed as well. For example‚ thirty-five years ago‚ the switch that dims the lights was on the floor. Most people are aware that the dimmer switch is now located somewhere on the steering column‚ but if a driver was unaware of how to use the switch‚ oncoming drivers could be blinded by the bright light and veer off the road and into the ditch.
