Answer:
1)
2)
Explanation:
1)
The intensity equation is given by:
Where:
- P is the power of the radio wave
- r is the distance from the source
2)
Now, the intensity and the electric field are related as:
Here:
- c is the speed of light
- ε₀ is the electric permittivity
- E is the electric field
We need to solve it for E.
I hope it helps you!
Answer:6.36 ft
Explanation:
Given
there is 110 ft of deer-resistant
area enclosed must be at least 700 ft^2
Let the length be L
and area of rectangular garden is 110\times L
thus
L=6.36
Therefore Length of garden must be at least 6.36 ft
This would be 3 kilometers, because there are 1000 meters in 1 kilometer. I hope this helps! Have a great day!
