Show that the discrete fourier transform of (0,1,-1,0) is (x, x, x2,x)-10, ( , (1+i) 24) find the dft of the time sequence (2,-2), compare it's amplitude spectrum with that of (2.-2,0,0) and comment on the effect on the amplitude spectrum of adding zeros to a time sequence 25) verify parseval's theorem for the series (2,-2,0,0) and the shifted series (0,2.-2,0) and comment on amplitude of a shifted time series.

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.

where are the vectors ?

conduction, convection, radiation

i would say
