can someone please explain why they only considered 0,2 and 5 as their frequencies and didn't include -2 and -5? Also, how did they get the angles for the changes column? please explain with steps. thank you 1. (i) (8 pts) The input signal z(t) to a continuous time (CT) linear time-invariant (LTI) system is given by x(t) 12 cos 2t +sin 5t The output y(t) is found to be given by y(t) 3-4 sin 2t 0.5 sin 5t At...
Can someone please explain why the ordering is A>D>B>E>C I know why c is first because it's primary and why A is last because it's tertiary the most stable but the middle is hard for me to understand. Reaction coordinate 2. Rank the following carbocations in order of decreasing stability

Can someone explain where r = d/2cos(a) comes from? also why H=I/pi*d cos^2(a) instead of just cos(a) Find the total field H at a point P, in the 2 wire transmission line if d-80 cm, α-300, and 100A, and the field halfway between the wires. 11 out r H2 in 21 cos α 2tr Resultant H at P-H, cosa+H,cosα 2π r 2Tr But 11,1-1121 H-L cosa
