Nobody would expect that Tino would even attempt standing up for himself against Erik‚ nor could they imagine how Paul “saved” Dino’s miraculous shot. But the odds approached and those events did happen in Tangerine. For those characters‚ they clarified possible instead of impossible‚ which lead people to think that Tangerine is a book of possibility. Tino always believed that he gets what he wants whenever he wants it‚ so if that meant for him to smack talk Erik‚ so be it. Paul figured it was

Discussion: There were some patterns that were noticeable during this experiment. It was noticed that all of the sprays with the metal potassium in them had turned the flame a light pink for a few seconds. The sprays that held the copper in them all turned the flame a vivid green colour‚ with some including green sparks also. Both of the sodium bottles turned the flame orange for a short time. Electrons orbit the nucleus of an atom in energy levels. If atoms are heated up to the point where the

Density of a given substance is independent of volume. Density never changes. I know that for a fact because during the “Density Does Not Change With Size” lab‚ we measured the length of rods given to us. For one I got 4.2cm‚ and when i weighed it on the scale I got 14.5g. Once I put the rod in the graduated cylinder I got 5.5cm squared. But when you divide your mass by volume‚ you will get your density. And for the density I got 2.6g/cm squared.Then for the other rod I got 6.7cm for length‚ 23.2g

Through his famous 1911 gold-foil experiment‚ Earnest Rutherford‚ a former student of Thomson‚ evolved the atomic model once again. Rutherford and his colleagues fired alpha particles‚ helium atoms that had lost their two electrons‚ at a thin piece of gold foil (only 0.00004 cm in width). They used a screen coated in zinc sulfide to "catch" the alpha particles after they had penetrated the gold foil. The screen would also emit a flash of light where it was hit by an alpha particle‚ which enabled

A refractory period is a period of time where the cells are resistant to depolarisation. There are 3 different refractory periods‚ firstly the absolute refractory period which is the part of the cardiac cycle where no further depolarisation can take place. Secondly it is the relative refractory period where depolarisation of the cells can occur but only if the stimulus is strong enough‚ and finally there is the diminished refractory period where the cells are still resistant to depolarisation but

AS Level Physics: Terms & Definitions:- Measurement Random errors are errors of measurements that result in a scatter of readings about a mean value. Systematic errors are errors of measurement which occur according to some fixed patterns such that they consistently give out an over-estimation or under-estimation of the true value. Accuracy is a measure of how close the results of an experiment agree with the true value. Precision is a measure of how close the results of an experiment

Assignment # 12 2.) How does the “standardized versus localized” debate apply to advertising? Communication takes place only when the intended meaning transfers from the source to the receiver. This can be a problem when a standardized approach is used. The message is not able to get through to the receiver due to different reasons such as lack of knowledge of the audience. There are people who feel an advertisement can be used anywhere in the world due to the converging tastes and preferences

Marketing is defined as a social and managerial process by which individuals and groups obtain what they need and want through creating and exchanging products and values with others.(Kotler.P 2002 : 5) The goals of marketing is to attract new customers by promising superior value and keep and grow current customers by delivering satisfaction. There are five core concepts of marketing‚ which includes needs‚ wants and demand; products‚ services and experience; value‚ satisfaction and quality; exchanges
