Is it possible to find the range without sketching the function?

What is the range?

Ah okay. Thanks for help guys!

Can someone approximate what my percentiles in the MedEntry exams would equate to if I performed as well in the actual UMAT? Exam 6: S1: 35/48; 77 S2: 33/44; 87 S3: 28/42; 87 Overall: 96/134; 88 Exam 7: S1: 36/48; 71 S2: 34/44; 81 S3: 32/42; 94 Overall: 102/134; 89 I went about...

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...

Ah okay, so overall, the graph would be more like this?:

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...

re: HSC Physics Marathon Archive

I am not confident that I can get a good enough mark in 4U Maths to use it for my atar, but I still want to try it. I've kept 12 units so that I have the ability to drop to 3U Maths if I need to.

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.

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...

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 :)
