i thought it should be under 30 degrees

a) time dilation b) use the time dilation formula, manipulate to get the v t=5, t0=2.2, c=3x10^8

which of the following relies on motor effect to operate A. DC generator B. galvanometer C. transformer D. AC inductino motor

where is the p?? its qvB

how come none of these are been mentioned in the Excel??? which one is the normal simple AC motor????

if you use the right hand rule, you'll see that B field will force the ion up. to deflect the ion, N terminal has to be negative.

same, i'll bet $5 on einstein

are you sure?? cuz last year there was a 8 mark question in quanta to quarks

what does it mean by integral spin and half integral spin??

how is electron microscope able to enlarge sample much greater than light microscope?? couldnt find anything in Excel

can u explain a bit more?? i dont understand this question

Compare how an absorption and an emission spectrum form and describe what they look like (8marks) i dont even understand what the question is talking about.....

CSSA 04 question paper also needed plz :(:(:(

de Broglie proposed that all kind of particles has both wave and particle properties, which explained why electrons do not emit radiation Hertz proved the existence of electromagnetic waves, he did observed the photoelectric effect but didnt go far enough

i believe its einstein

its 4:21 now :p :p :p :p :p

isnt the answer D?

Meson is in the quanta to quarks topic they are combinations of a quark and an antiquark, they are unstable and decay in millionths of seconds. however evidences showed that their lifetime is being dilated when penetrating the earth's atmosphere at very high speed, which provens the time dilation
