For the following questions answer them individually
A resistor and a capacitor are connected in series with a sine wave generator having frequency suchthat the resistance and the capacitive reactance are same i.e. voltage across capacitance, $$V_c$$ is equal to Voltage across Resistance, $$V_R$$. If the frequency ofthe sine wave generator is doubled, then
A plane wave with a frequency of 3 GHz is propagating in an unbounded medium with relative permittivity $$ε_r = 6$$ and permeability $$\mu_r = 1.5$$, the phase velocity for this wave in this medium is
A wave is incident from free-space onto a dielectric region of dielectric constant $$ε_r = 4$$. The wave impedance in the dielectricis :
Range resolution of a Linear Frequency Modulated pulse compression radar depends on whichof the following factors:
The orbital period of a satellite in circular orbit of radius R from the centre of the earth, is proportional to:
