AS level ICT
Well, its actually difficult for me to say what is wrong without seeing ur work. U can try by opening a blank report and then selectthe query u did as the record source( Report Design Tools>Design>Tools>Property Sheet> Record source) Or else try from the beginning and try to recall what u did... -

Physics Amplitude-Modulation
this question is from the International AS/A level Physics book, pg - 428 the question: A sinusoidal carrier wave has a frequency of 750kHz and an unmodulated amplitude of 4.0V. The carrier wave is to be amplitude-modulated by a sinusoidal signal of frequency 3kHz and the amplitude 0.5V... -
Something interesting here!!!!!!!
Volume of funnel, V = 1/3 x pi x r^2 x h dV/dh = (1/3) x pi x r^2 using similar triangle, 12/30 = r/20 r = 20 x 0.4 = 8 when h = 8, dV/dh = (64/3) x pi now, dV/dh = dV/dt x dh/dt dh/dt = (dV/dh)/(dV/dt) = ((64 x pi)/3)/(0.2) -
help needed Physics O/N/2004 P1 Q 18,,,,,,
we know P = F x V which can be written as P = (F x d)/ t putting the given data 3 x 1000 = (180 x 4 x 1000)/ t which gives t = (180 x 4 x 1000)/(3000 ) = 240 s -

Physics...May/June 08
the area under 40 to 70 is not taken as the spring has been compressed from 100 to 70 but not 70 to 40. the initial length was 100 when there was no force. as the force is applied, the spring compresses and energy is stored. when the force is 6 N, the spring becomes 70 mm. a decrease in length... -
Physics...May/June 08
Since the spring is compressed, initial length is 100 mm and final length is 70 mm and thus the energy stored will be the area under the graph from 70 mm to 100 mm. energy = 0.5 x (6-0) x (0.1 - 0.07 ) [converted to meter] = 0.09 J hope that helps :) -

Only 1 mole of HCl is produced, this means only one H atom has been substituted by a Cl free radical, One X* is formed by substituting H from either of the three methyl groups attached to the same carbon atom 2nd and 3rd is formed by substitution of H form the ethyl group -
Maths Query!
Well, the question did not specifically asked u to find to theta. I think u can also do it like this way, rearrange which gives X - sin X - pi/2=0 let f(X)= X - sin X - pi/2 when X = 2.31, f(2.31)= 1.9839 x 10^-4 which is approximately zero thus x = 2.31 -

the easy way of solving this eqn using iteration (iteration is not included in AS but in A2). there's another way which is also not included in AS. However, i am not sure whether there is any algebraic method to solve it. Can't think of any...... -
Chemistry!!!MCQ
u r in the right track, one of the alkenes formed shows cis-trans isomerism, if u examine the alkenes formed after dehydration, u will notice that butan-2-ol is the correct ans.
