Answer:
If the frequency of the source is increased the current in the circuit will decrease.
Explanation:
The current through the circuit is given as;

Where;
V is the voltage in the AC circuit
Z is the impedance

Where;
R is the resistance
is the inductive reactance
= ωL = 2πfL
where;
L is the inductance
f is the frequency of the source
Finally, the current in the circuit is given as;

From the equation above, an increase in frequency (f) will cause a decrease in current (I).
Therefore, If the frequency of the source is increased the current in the circuit will decrease.
Answer:
Explanation:
Given that,
Frequency of radio signal is
f = 800kHz = 800,000 Hz.
Distance from transmitter
d = 8.5km = 8500m
Electric field amplitude
E = 0.9 V/m
The average energy density can be calculated using
U_E = ½•ϵo•E²
Where ϵo = 8.85 × 10^-12 F/m
Then,
U_E = ½ × 8.85 × 10^-12 × 0.9²
U_E = 3.58 × 10^-12 J/m²
The average electromagnetic energy density is 3.58 × 10^-12 J/m²
I hope I am correct my Science teacher said this was the answer to your question
Answer:
This process of weighting attributes is used ______.remove the connection among the various attribute in the set of specification and to set priorities
Explanation:
The process of weighting attribute is used to remove the association among attributes in a sample set as some attributes are considered more important than others. The weighing serves to indicate the desirability for an attribute with respect o the other attributes
As such, the weighting is used to set the order of importance, and to indicate the priorities
Answer:
travels along a curve due to uniform gravity
Explanation:
General relativity
The theory was developed by Albert Einstein , it is the theory of gravitation , according to which , the gravitation effect which is observed between the masses , is the resultant of their warping of the space time .
In general relativity , the equivalence principle is the equivalence of inertial gravitational mass .
According to which , the light bends due to gravitational forces ,therefore , the light travels along a curve because of uniform gravity .
