between the hole in the ozone layer and global warming we must first understand what they are. The hole in the ozone layer is mainly over Antarctica but can sometimes be seen over the North Pole. The ozone depletion is caused by CFCs that were released by aerosol cans and refrigerates before they were banned in 1996. Yet these chemicals don’t disappear right away they can stay in our atmosphere for over fifty years causing the molecules of the ozone layer to breakdown creating a hole. Global warming

Parachute experiment Aim: The aim was to find the effect of holes on a parachute‚ varying their size and number. Hypothesis: 1. By increasing the number of holes‚ the time it will take to the parachute to reach the ground will be longer and its flight will be more balanced. 2. By increasing the size of the hole on the parachute‚ the time it will take to the parachute to reach the ground will be shorter and its flight will be less balanced. Apparatus: - garbage bag (squared shape

is called built-in potential Vbi. After joining p-type and n-type semiconductors‚ electrons near the p–n interface tend to diffuse into the p region. As electrons diffuse‚ they leave positively charged ions (donors) in the n region. Similarly‚ holes near the p–n interface begin to diffuse into the n-type region leaving fixed ions (acceptors) with negative charge. The regions nearby the p–n interfaces lose their neutrality and become charged‚ forming the space charge region or depletion layer (see

salvation by creating relations to biblical events. He uses the hole to express the idea of a loss of freedom by showing the hopes of Andy being taken away when he is sent to the hole. The hope of freedom that is felt by the inmates is conveyed to the audience through the clever use of music and symbols of music throughout the film. Frank Darabont conveys the idea of a loss of freedom through his use of “the hole” as a motif. The hole is a place where a prisoner’s limited freedom is taken away from

question‚ because these later objects are made of elements that can only have been created by the first generation of stars. It is still unknown whether the Universe created black holes with the first generation of stars or whether these exotic objects were created by the first generation of stars. Because black holes represent the most extreme physical conditions of spacetime and generate some of the most energetic phenomena following the Big Bang‚ they are the ultimate physical laboratories for

It must be modified by cutting three holes into the grip front wall to the measurements supplied below. The grip consists of a 5-1/8” length of 2’’ x 1’’ tubing. The wall thickness of the tube should be 2.5mm. The holes are drilled to the following diameters:

lets think big.....what if instead of the pyramid it was a black hole? The mass of a black hole is huge!Time around it would move very slow compared to its farther surroundings.If we were to send a rocket containing people to orbit that black hole time would move differently for them and for us here on earth.For instance if time around the black hole corresponds to twice the time elapsed on earth after one day of orbiting the black hole two days would have passed on earth.But in reality it will be on
