Speech My speech will be about Global warming‚ this is the rise in the average temperature of the Earth’s atmosphere and oceans. In 2011 the emission of carbon dioxide and was the highest it had ever been before and it had also taken a similar jump in 2012. Over all‚ emissions of carbon dioxide had jumped 3 percent in 2011 and in 2012 it was estimated that it had jumped another 2.6% in 2012. Scientists are 90% sure that Humans are the cause global warming from producing greenhouse gases produced

to measure acceleration on a freely falling object assuming the only force acting on the object is gravitational force. Theory All dense objects in free fall have the same acceleration‚ which is known as the acceleration due to gravity. The value of acceleration due to gravity is approximately 9.80 m/s2. In this experiment‚ a vertical stand with an electromagnet at the top for holding and then releasing of the falling body‚ called the plummet. The plummet falls between two vertical wires
