high thermal capacity means that
more amount of energy would be needed to change the temptertature of a body by 1degreed

for example
2 kg of aluminium has less thermal capacity than 2 kg of water...
aluminium loosoes and gains temperature faster than water..
thus the low thermal capacity
in this case water has high thermal capacity

IMHO it actually depepends on the mass
in the question
BEST OF LUCK everybody

thermal capacity can be different for 2 objects of the same material, but different masses. Its SPECIFIC heat capacity that has to be same for similar materials.

I got the Fraction 1/8..Cause u divide 1/2 the mass and the speed too..I'm pretty sure it correct but why the heck they gave us the diameter of the
thingy??the turbine or whatsoever? For the Diode I"M SURE 100% its A.I did the experiment in Sec3.

For the PD ACROSS S WHEN THE SWITCH IS Open is 0 volt and the same goes for the next question.

Pressure should not be halved for the swimming pool thing.

FOR THE MICROMETER, you should mention Datum line, ratchet and thimble..Well, that my opinion..

Wow Wahab09..You're good!

^ the pressure of water at that point remains unchanged as the density, height and g are the same=> pressure= d x h x g.......

Physics paper 1 was soooo easy!!!  ;D
I might even get full!!
Im amazed at some of the people's mistake. They kinda fell prey to CIE's tricks.
