Things to look for. Multiple Sources with same information. The person who has written the information is the primary source and they have appropriate qualifications in the information they are supplying or they are an expert who has assessed the data they are supplying. The information is...

err technically no. It consists of a rotor and a stator. Induction motors and AC motors don't fit your description.

What is a motor? Something that produces KE. This produces KE and can move something so its a motor. But it is a discuss, so you should also be saying why it isn't a motor.

It depends on why the scheme is being run. Eg Some are made on geopgraphical reasons. Eg Wollongong http://www.uow.edu.au/prospective/bonus.html Even a selective high is given this advantage.

Maybe he should have a discussion with professor joseph f becker, san jose university http://www.physics.sjsu.edu/becker/physics51/induction.htm

Same as last years question using DC A transformer can work off a DC supply as long as there is a method of changing flux. Most of the induction coils you see at school to power cathode ray tubes are DC supplies, that are transformed. There is an electromagnetic switch to turn them on and off...

Yes, not reading the question normally does make them easier Question quoted again Parts of a space mission involve a spacecraft spending time in geostationary orbit and then returning safely to earth Analyse the forces acting on this spacecraft during these parts of the mission

Ask nicely for any spares

After it passes the anode it is out of the electric field, so is no longer being accelerated, so can be assumed to be an inertial frame.

Your not measuring the rest length of the electron. You are measuring the length between the anode and the screen. This is moving wrt the electron, so assuming the electron can observe as it states in the question, then it will be contracted as observed by the electron.

The question as I posted is a direct OCR of the paper. I have also posted the paper http://community.boredofstudies.org/686/physics/125704/part-b-question-paper.html

Question In a special investigation, the voltage between the cathode and the anode is increased so that an electron gains a velocity of 0.60 c, where c is the speed of light. The electron starts from rest at the cathode. Calculate the mass of this electron in the laboratory frame of...

No and Meissner effect is wrong as the highest critical temp is about -135 celcius Copper is not a superconductor at -50 http://hypertextbook.com/physics/modern/superconductivity/

Nothing to do with superconductors as highest critical temperature for any material is about -135 degrees celcius and copper is not a superconductor at -50 http://hypertextbook.com/physics/modern/superconductivity/

It can be worked out from Lenz's Law and eddy currents.
