Q7 a) Shouldn't the result for 3 test in the table be 30 Ohm, why is it 15.
What should have been the result if S1 and S2 were closed and S3 was open.

Q1 why not D
and Q2 as well

 

[princess Anu]

Explain both of these please
for the second one, my question is how do we know if the system is isolated and the conservation of momentum can take place? shouldn't we consider air resistance as an external force and so the answer should be A, no?
