Thanks sir, you're a life saver. Was struggling through trials past papers and wanted to know where I was missing out on content. I got plenty of practice while following with your video and identified where I had gaps in my knowledge. Also you explained everything super simply but thoroughly further deepening my understanding.

Glad it helped. Hope you go well on your trials.

I thought for question 30 B) ii) if there is a cut in a ring, there would be no induced current and therefore no emf induced. I would have actually put 0 volts lol. Thanks for the explanation.

At 34:53, should the distance be 4 instead of 2? Since its the distance from the initial position of the launcher to its position at 1.16s.

for q26 does it matter if you do mproducts-mreactants or mreactants-mproducts?

[@PhysicsHigh]

Doesn’t really matter, you get the same numerical number. Just one is negative. The other one is positive. The important thing is that the reactants should be greater than the products, since mass is lost but as a result energy is gained due to mass energy equivalence.

For question 33, How many experiments should be referenced in my response?

[@PhysicsHigh]

In any question where you are to justify your position, I would ensure you would have at least one piece of evidence. in this case at least one experiment However, depending on the question, especially anything worth 7 to 9 Marks, I would provide a minimum of two pieces of evidence in order to demonstrate extensive understanding of the concepts
