A certain transmission line is 10 meters long. Measurements indicate that the total inductance of the cable is 16 uH. Standing wave measurements indicate that the voltage reflection coefficient at the load is 0.5 + j0 when a 75 ohm resistor is connected to the line. What is the capacitance per meter of the cable? (Hint: Find Z0 first.) What is the velocity of propagation in the cable?
When electros and holes are present in a semi-conductor, the presence of an electric field produced by an external voltage will cause this carries,which have changes of oposite sign, to move in opposite directions.
How tall must the antennas be if the link operates on a frequency of 2.450Ghz, D1=5miles, D2=11miles, and the obstruction is 60 feet high?

If a transformer has a turns ratio of 1:5 and a primary voltage of 20 V AC, what will the secondary voltage be?
20 SI fibers, 2 km long each, are spliced together for a 40 km link. Each fiber has a loss rate of 1-dB/km and a numerical aperture of 0.24. Each splice adds 0.5 dB of loss. A laser diode has a threshold current of 10 mA and emits at 3 mW/mA rate.
A bowling ball is placed on a coil spring. The spring constant is 400N/m. When the bowling ball is placed on the spring, the spring compresses down 0.1m. If the spring is vertical how far will the bowling ball go
