I believe the correct answer is "<span>Constructive interference occurs when the crest of one wave overlaps the trough of another and their individual effects are reduced or cancelled out."</span>
I'm assuming that's a typo, and the rock station is at 107.1 MHz .
The lower frequency radio waves, emanating from the opera
station, are longer.
Each photon of radiation with higher frequency, emanating from
the rock station, has more energy. But the total energy radiating
from each station depends on the power level of their transmitter,
not on their frequency.
I don’t know because it’s very difficult
The time taken is approximately 26 minutes
Explanation:
The motion of the body in this problem is a uniform motion (= at constant velocity), therefore we can use the following equation:
![v=\frac{d}{t}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bd%7D%7Bt%7D)
where
v is the speed
d is the distance covered
t is the time taken
In this problem, we have
v = 75 km/h is the speed
d = 32 km is the distance to be covered
Solving for t, we find the time needed:
![t=\frac{d}{v}=\frac{32}{75}=0.43 h](https://tex.z-dn.net/?f=t%3D%5Cfrac%7Bd%7D%7Bv%7D%3D%5Cfrac%7B32%7D%7B75%7D%3D0.43%20h)
Converting into minutes,
![t=0.43 h \cdot 60 = 25.8 min \sim 26 min](https://tex.z-dn.net/?f=t%3D0.43%20h%20%5Ccdot%2060%20%3D%2025.8%20min%20%5Csim%2026%20min)
