An Am transmitter supplies XKW to the antenna when it is unmodulated if the total power radiated by the transmitter is YKW when the modulation index is m. given that the unmodulated wave is V while antenna load is R . show that m=(2x^-1(y-x)^1/2

the results is a decrease in air temperature with an increase of altitude.

explanation:

a longitudinal wave moves energy that is to the direction of the wave’s movement. - true

igneous rocks also form where plates converge. the subducting plate melts as it sinks into the crust of the earth, and the melt rises into the overriding plate forming volcanoes. metamorphic rocks are formed mainly in the lithosphere, wherever there is high pressure and high temperature. -woods
