Wavelength × frequency = speed
Answer:
By ‘inserting’ you means to putting a resistor in series. In this case, no, there is no resistance that would produce the same effect as a short circuit.
If you adding a resistor in parallel with the circuit, then if it had a low value It might be similar to a short circuit. I
Density = mass / volume = 7/14 = 0.5!g/cm^3
