WAT DID U GUZS WROTE 4 THE 1 ST QUESTION
--- End quote ---
i wrote vernier calipers...although i know of a micrometer..dont really know how it works..but i do calipers..so wrote tht..i messed up in the milk and water part..thts the only q im sure busted in, rest was good enough
--- End quote ---
IF U KNOW how to use calipers than i guarantee u its 110% correct!!!!!!
i knew da word micrometer and this one but i didnt know how to use it!
i am sure u dont live in ksa!!!!

Because it has a slower speed which means a heavier mass, right?

u dont know how glad i am to know i isnt the only one who got half!!!!!!!!!!wohoo

half the speed means half volume of air comes to the turbine, thus, half the original mass..isnt it?

and i just wanna no hw u people found ur values of mass?????????
--- End quote ---
ur idea maybe correct!!!1
but since it was a 1 mark question!!!!
i halved the mass
as the da speed was halved
