Answer:
The total power is
Explanation:
From the question we are told that
The distance is
The amplitude of the electric field is
Generally the average intensity of the electromagnetic field from the radio transmitter is mathematically represented as
Here c is the speed of light with value
is the permeability of free space with value
So
=>
Generally this intensity can also be mathematically represented as
=>
=>
=>
Answer:
<h3>10.0m</h3>
Explanation:
The displacement of the dog is the distance moved in a specified direction. It will be gotten using pythagoras theorem as shown;
d² = 8²+6²
d² =64+36
d² = 100
square root both sides
√d² = √100
d = 10m
Hence the displacement of the dog to the nearest tenth is 10.0m
C. The Uniformity of Cosmic Background Radiation
Answer:
Γ = r x F vector notation for torque
Doubling r (the length) will double the torque applied
