    Acceleration of a magnet as it falls through a metal tube

    So how do you explain the shape of this graph in terms of the induced eddy currents? Do they increase in size and cause a lower acceleration? Also, is this correct: As the acceleration decreases, the rate of change of flux decreases As a result, the induced emf decreases The eddy...

    Acceleration of a magnet as it falls through a metal tube

    How would you draw a graph for the acceleration of a magnet as it falls through a metal tube? From my understanding: Before entering the tube, it's acceleration would be 9.8 As it enters the tube, it's acceleration would become lower As it is traveling through the tube, it's acceleration...

    Regarding Standard English and Advanced English

    Thanks for the advice guys. Just wanted to add that I am doing Chemistry, Physics, Biology, 3U and 4U Maths for Year 12 also. My teacher said it might be a good idea to drop due to the workload of those subjects, and some of my friends thought the same.

    Regarding Standard English and Advanced English

    I have not been going as great in Advanced English as I would like to be. My results throughout Year 11 are x/42 (didn't finish writing), x/30 and x/30, with my ranks being x/167, x/167 and x/167 respectively. This brings me to a cumulative rank of x/167. Do you think it would be a good idea to...

    Physics Moving About Question

    Can someone help me out please? Here's the question: Calculate the acceleration of a car moving at a constant speed of 20m/s in circular motion if it takes 40 seconds to complete one lap. [Hint: Use vectors to work out change in velocity (v-u)] Thanks :)
