Sir J.J.THOMSOM is to physics what electron is to an atom. He charged the world of physics with his discoveries and gave momentum to atomic physics. Physics is what today because of this British scientist who is regarded as the greatest experimental physicists of this century. A bookseller’s son‚ Thomsom studied at the Owens College and later at the Manchester University. He wanted to become an engineer‚ but his father’s death in 1872 forced him to study Mathematics‚ Physics and Chemistry as he

Year 12 Physics 2014 ER – The Physics of Medicine Extended Response Task [Type the author name] This report will discuss how cerebrovascular disease‚ in particular ischemic stroke‚ can be diagnosed using magnetic resonance imaging scans. It will go through the different MRI sequences and the physics behind them. Evidence from two case studies are presented‚ which use the MRI sequences discussed within this report. Consequently‚ the recent advances in diagnostic techniques and methodologies will

Required Vocabulary – IB 12 Higher Level Physics and Physical Measurement 1. Fundamental Units – seven basic units of the SI measurement system: kilogram‚ second‚ mole‚ meter‚ ampere‚ Kelvin‚ candela. 2. Derived Units – units that are combinations of fundamental units. These combinations may or may not have a separate name. (eg. 1 kg m/s2 = 1 N) 3. Accuracy - An indication of how close a measurement is to the accepted value (a measure of correctness). 4. Precision - An indication

Introduction I have chosen to investigate a factor that affects the output of a potential divider circuit. A potential divider is resistors connected in series across a voltage source; used to obtain a desired fraction of the voltage. A resistor is a device having resistance to the passage of an electric current which affects the output voltage (Vout). The factors that I could investigate are changing the resistance of r2 and record the output (Vout)‚ or use a light-dependent resistor (LDR) and change
