Answer:
D
Explanation:
A. Polarization is simple for most antennas to determine. It is only on the same level as the antenna components. A vertically polarised antenna (that is one with vertical elements) is better received and a horizontal antenna is equally provided with horizontally polarised signals.
B. The left-hand circular polarization is named if the electric chambers vector rotates counter-clockwise as far as they are from the antenna.
The right-hand circular polarisation is named as the electric field vector rotates counter-clockwise as far as it gets from the antenna.
It then goes without stating the polarisation on the right hand is orthogonal to the left.
C. signals of the same frequency can be transmitted together in an non-interfering manner as long as their polarizations are orthogonal to one another. This too a correct statement.
The only electric appliance in a 120-volt circuit is a microwave. If the circuit has a 7. 5 amp current, the microwave's electric output is 900 watts.
<h3>Explain about the
microwave's electric output?</h3>
As was previously said, 1000W is the most common microwave wattage . The real power usage of a 1000W microwave, or its average input wattage, is 1402.7W. In a microwave, it is always more important to pay attention to the input wattage than the output wattage.
The energy that can be used in a microwave to heat and cook food is represented by this number. Typically, the power output is expressed in Watts, for example, 900 Watts. The appliance's whole wattage consumption used to produce microwave energy is the input.
A microwave can consume anywhere from 600 to 1,000 watts (W) of power. When connected to a 120-volt outlet, microwaves draw roughly 10 amps. The largest influence on how much electricity your microwave uses over time is how frequently you use it.
