Answer:
Intensity of the transmitted radio wave is 5.406 x 10⁻⁶ W/m²
Explanation:
Given;
power of radio transmitter, P = 63.2 kW = 63200 W
distance of transmission, r = 30.5 km
Intensity of the transmitted radio wave is calculated as follows;
where;
I is the intensity of the transmitted radio wave
Substitute the given values and calculate the intensity of the transmitted radio wave;
Therefore, Intensity of the transmitted radio wave is 5.406 x 10⁻⁶ W/m²
Answer:
208
Explanation:
add it together for the answer
The answer is d. I hope that helps.
Answer:
Explanation:
The speed is 0.7 m/s.
The distance covered is 1609 m.
Multiplying both sides by <em>t</em>.
Then dividing both sides by 0.7.
It would take 2298.57 seconds.
