Both tubes do experience eddy currents. However in the copper tube, there is a greater retarding force (more eddy currents) which allows the opposition of motion (Lenz's Law). As a result of Lenz's law, the magnet dropped through the copper tube is slowed down. The tube with the vertical cut...

Try to understand the logic behind the formulas and then apply it to set textbook questions. Eventually with heightened practice, it'll become second nature and then just do some past paper questions to consolidate that knowledge so you know the layout of practice questions.

Try nerdasad's sig, there are some quality past papers there or even so ask your teacher for some past papers; they should have a batch of them.

helpful advice

I suppose you're talking about the difference between compound interest and superannuation questions? It's all about the question: Compound Interest: Use the formula when the question specifies that there is an amount being deposited ONCE only initially and is being compounded by an % rate...

Faraday's law of electromagnetic induction relies on a CHANGING magnetic field to induce voltage. Remember AC currents are constantly fluctuating thus allowing a voltage in the secondary coil. Since DC currents in a coil produce steady magnetic fields, (flow in one direction/conventional...

More of an MG fan tbh, i love motors and generators as opposed to space *shudders thinking about relativity*

Practice makes perfect.

1) Physics - Right hand palm and grip rule stuff like that, there are some stuff from electrical energy in the home that are in motors and generators and also some stuff that bos expect you to know (space has some cosmic engine presumed knowledge in it) 3) MX1 (I'm planning to do MX2) - lol...

Use it as a study guide, to see the standard and to see if you can actually complement your understanding with other's notes and information. You benefit much more that way.

Divide by 4? That's gives you a quadrant

what stage are you upto? have you found the ordinates for your integral and your area of the semicircle?

Agreed. Higher rates with your preference but if you're looking to tutor at a tuiton,most tuitons offer around the same rate unless you're incredibly good at what you do.

plenty of people aha, they are incredibly naturally talented.

Lol agreed, stick to dotpoint summaries but reinforce understanding with the textbook as it's heaps helpful if you don't get something

Literally billions of case studies out there. Don't limit yourself to 1-2 case studies, a hsc marker is always looking for an abundant amount of case studies to back up each argument of your extended response. Look them up, i'd say qantas, apple and microsoft are pretty big ones; read the news...

Pre-Uni, it's great to go to during your junior years, but i'd think thrice before thinking about enrolling at Preuni in years 11 & 12. I'm in year 12 right now, and i can personally say that despite for English (eventually dropped), IT IS NOT WORTH IT. They hire people who got over 99+ atar...

My bad, 251

Can i get a rough estimate of ranks required for me to get a 95+ atar? school rank: 250 Cohort size: physics: /70 business: /55 eng adv.: /40 maths ext.: /60 maths 2u.: /112 ipt: /21
