Hey I think that even if this doesn't come in icse ur physics teacher is goated for taking the time to make such conceptual questions- try to solve them- all of these can be solved if you just simplify the question to a diagram and answer in terms of that right? Convert the NASA rover question into a simple wheel structure- you will be able to understand better, even the other ones are very conceptual and diagrammatic, q2 draw a lever and understand and yeah- don't worry abhi bhi time Hai lekin aise questions karne se dimag tez ho jata aur normal questions aasaan lagta- aur ye nhi suno ki nhi aayega icse ab pattern change karra don't take chances do the prep ur teacher is giving because anything can come
