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).

Imagine you had to physically add electrons, one at a time, to a previously neutral conductor. you add one electron very easily, but the second electron requires more work. in your initial post to the discussion, explain why this is. also, what happens to the work needed to add the third, fourth, fifth, and subsequent electrons

Astone is dropped with no initial velocity from the top of a cliff and hits the ground a time of 3.9 s later. what is the height of the cliff, in units of meters? you may assume that air resistance is negligible. give the answer as a positive number question 15 a figure skater is rotating at a rate of 200 revolutions per minute. what is the angular speed, in units of rad/s? 200 o 20.9 12000 o 3.33

Wavelength,frequency,and energy are related.what happens to a wave as it’s wavelength gets shorter?
