Yeah it was the amplitude in some SHM question in 42.

Not every physics paper has SHM about Needles, i only saw that in 2 paperstemp was below 297.
And we didnt get any question about SHM of any needle and we gave paper 42 :s wtf?

thanks gary 221,but you are wrong,DAC and the serial to parallel are not the smaecheck this diagram out(mobilephone flow chart)if they are the same why are they kept seperateADC = samples the signal at regular intervals. for each sample, produces an 8- bit binary no. So DAC = will convert the binary no to a decimal no ie to an analogue signal.
Parallel to serial = takes the 8 bits from 1 sample n places them after the 8 bits from the previous sample to produce a continuous series of binary digits.
So, serial to parallel must do the opp. ie assemble the 8 bits, n pass them to the DAC for conversion into analogue. then, pass the next 8 bits to produce the next signal, n so on.
Did I say tht they both r the same??
I guess not : "The serial to parallel converter n the DAC produce an analogue signal" does not imply they r same.
And if I did say they r same, sorry, m bad!!

This is one of the most easiest papers ever. Anyone who got like a C in their AS can jump to an A. InshAllah.
no but the q said write expression in cm of how s related to tAwkward in sense that the pattern was really much changed. No op amp circuits plus I was highly expecting MRI to come.
And for SHM apmlitude was 0.021m
how ws temp below 297 ? r u suretemp was below 297.

your answer is righti wrote same but i gave a diff reason i referred to newton's laws :/
The qus just askd u to relate the equations dats all...no but the q said write expression in cm of how s related to t
how ws temp below 297 ? r u sure
yes but whether amp to be used as 0.021 or 2.1The qus just askd u to relate the equations dats all...
U were suppose to write 0.021 not 2.1..yes but whether amp to be used as 0.021 or 2.1
i did do it in metres for the calculation for energy, but i have a strong feeling it ws written in cm in the q for equation cuz before putting the values i ws seriously considering whether they wanted it in m or cm,,,,oh well maybe i did write 0.021U were suppose to write 0.021 not 2.1..
NO!
There was nothing such written & we had to write in m not cm.
For displacement
X = 0.021 Cos (w) t [Can't remember what was omega)
For Velocity
V = - 0.021 Sin (w ) t x (w)
how ws temp below 297 ? r u sure
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
