1.1 If the Sun should suddenly explode (it can’t) how long would it take for us to notice the event? * According to scientists we have at least 5-6 million years before the sun would ever die out or explode. However if a phenominon like that were to occur there are diffent theories to what might happen. It would take light from the explosion eight minutes to travel the 93 million miles from the sun to the earth. However‚ Newton’s Law of Gravity claims that Earth would suffer an immediate departature

Studying theater. Being a singer. Travelling around the world. Being famous. Being president of the United States. The truth is that all people have dreams thwarted. We all dream of something‚ no matter how we may appear. Steve Jobs‚ Bill Gates‚ Michael Jackson‚ Justin Bieber. They also had a dream that once seemed crazy. And you know who differentiates them from us? They used their imagination. Yes. they imagined their dreams becoming reality and thanks to that found ways to do it. And you know

baby till it shined? If so you probably would be interested in a career as an auto body mechanic! To be an auto body mechanic you must have at least a grade ten education and some employers will also ask you for your high school diploma. So it will be in your best interest to finish high school. You will also need to show that you finished an apprenticeship program as an auto body mechanic and collision damage repairer automotive painter or have a combination over three years of

Applied Behaviour Analysis (ABA) What is Applied Behaviour Analysis (ABA)? Applied behaviour analysis‚ commonly referred to as "ABA" is a systematic method of supporting and/or altering behaviour. It involves studying behaviour (via observation)‚ analysing the steps involved in producing a behaviour‚ and then teaching or modifying these steps one at a time. The principles of behaviour therapy have been developed through more than 50 years of scientific research. Key components of ABA are:

belief that the education in manufacturing engineering that I have received until now has helped me to grasp the fundamental principles of the subject. This knowledge coupled with dedicated master’s study would be the ideal preparation for a career in applied research or academics in the manufacturing. It is for this reason that I wish to pursue a Masters course in Manufacturing Engineering in the “Materials Engineering and applications

Continuum Hypothesis in Fluid Mechanics The macroscopic behavior of fluids makes them appear to be continuous. However‚ when viewed at the microscopic scale fluids cannot be viewed as continuous. The fluid under consideration will have molecules bombarding each other. It is not possible to declare the fluid velocity at a point as there is no guarantee that the fluid molecules are present at that point at a particular instant of time. When we calculate the fluid velocity or density at a point it

Classical and Quantum mechanics are the two main fields of mechanics in physics. Classical mechanics came a few hundred years before Quantum mechanics. Subsequently it is less accurate and less reliable then the more recent mechanic field of Quantum mechanics. Despite being outdated‚ Classical mechanics can still be used for many everyday problems with bigger and slower moving objects. However‚ when dealing with extremely fast moving or small subatomic particles a Classical approach will not
