Acarrier s(t) = 100 cos (2 × 109t) of an fm transmitter is modulated with a tone signal. for thistransmitter, a 1-v (rms) tone produces a deviation of 30 khz. determine the amplitude andfrequency of all fm signal components (spectral lines) that are greater than 1% of the unmodulatedcarrier amplitude if the modulating signal is m(t) = 2.5 cos (3 × 104t).

Which situation will produce the greatest change of momentum

Two resistors r1 and r2 may be connected either in series or parallel across an ideal battery with emf ε. we desire the rate of energy dissipation of the parallel combination to be 8.75 times that of the series combination. if r1 = 105 ω, what are the (a) smaller and (b) larger of the two values of r2 that result in that dissipation rate?
