B. Either vertically or horizontally polarized antennas may be used for transmission or reception
C. FM voice is unusable
D. Both the transmitting and receiving antennas must be of the same polarization
Answer:
B
Explanation:
The fact that skip signals refracted from the ionosphere are elliptically polarized is a result of either vertically or horizontally polarized antennas may be used for transmission or reception.

Answer:
the relative compaction is 105.88 %
Explanation:
Given;
dry unit weight of field compaction, = 18 kN/m³
maximum dry unit weight measured, = 17 kN/m³
Relative compaction (RC) of the site is given as the ratio of dry unit weight of field compaction and maximum dry unit weight measured
Relative compaction (RC) = dry unit weight of field compaction / maximum dry unit weight measured
substitute the given values;
RC (%) = 105.88 %
Therefore, the relative compaction is 105.88 %

effective delay =
Answer:
voltage across the capacitor's is 75 μF
Explanation:
given data
capacitor = 15 μF
voltage = 50V
dielectric constant k = 5
to find out
voltage across the capacitor's
solution
we will find here voltage across the capacitor's by this formula
voltage across the capacitor's = k
here k is 5 and = 15
put these value we get
voltage across the capacitor's = k
voltage across the capacitor's = 5 ( 15 ) = 75 μF
so voltage across the capacitor's is 75 μF
Answer:
L = 75.25 mm
Explanation:
First we need to find the lateral strain:
Lateral Strain = Change in Diameter/Original Diameter
Lateral Strain = (20.025 mm - 20 mm)/20 mm
Lateral Strain = 1.25 x 10⁻³
Now, we will find the Poisson's Ratio:
Poisson's Ratio = (E/2G) - 1
where,
E = Elastic Modulus = 105 GPa
G = Shear Modulus = 39.7 GPa
Therefore,
Poisson's Ratio = [(105 GPa)/(2)(39.7 GPa)] - 1
Poisson's Ratio = 0.322
Now, we find longitudinal strain by following formula:
Poisson's Ratio = - Lateral Strain/Longitudinal Strain
Longitudinal Strain = - Lateral Strain/Poisson's Ratio
Longitudinal Strain = - (1.25 x 10⁻³)/0.322
Longitudinal Strain = - 3.87 x 10⁻³
Now, we can fin the original length:
Longitudinal Strain = Change in Length/L
where,
L = Original Length = ?
Therefore,
- 3.87 x 10⁻³ = (74.96 mm - L)/L
(- 3.87 x 10⁻³)(L) + L = 74.96 mm
0.99612 L = 74.96 mm
L = 74.96 mm/0.99612
L = 75.25 mm
