omg ur a genius this is the easiest way I've seen of doing questoon 10... I've been looking for an easy working everywhere and people were giving equations of things which arent even in the syllabus.. ur the best❤
for the half life question no 40, if they want 2 half life means that we need to divide 2 times and the answer will be 4 min right? i need asap answer tq..really luv the video
Hi, half life period is a time taken for an amount to be halved. Look at Q40, original rate is 120. Half of the rate will be 60. Time taken for that rate to be halved is only 2 minutes. So half life for this substance will be 2 minutes. Hope you can understand. All the best.
hi, sorry just noticed your message , for that questions you have use R=length of the wire/ surface area of the wire surface area of circle = area of circle= pie x radius^2. or pie x (diameter/2)^2. and you have to compare both equations to get resistance of the second wire.

Glad I could help!
For question 8, why do we have to change the unit from g to kg?
for any force formula,
F=MA
Ft=MV-MU
the mass need to be calculated in kg.
SI UNIT for mass is kg not g.
i hope this helps you
Thank you soo much! I have my paper 2 tommorow, cant thank you enough
