Hello!
The velocity function is:
a) 2.3 s earlier, we can make
t = -2.3 s, in relation to our initial time:
b) Now we can make
t = 2.3 s:
Answer:
Radio stations have dipole type antennas
this field increases in intensity and propagates outwards,
Explanation:
Radio stations have dipole type antennas, that is, all sides are isolated from each other, when the AC signal from the radio station arrives, the lcharge begins at times and by the Lens law a field appears that opposes this movement, this field increases in intensity and propagates outwards, when the voltage reaches a maximum, the generated wave also reaches the maximum, now the incident wave begins to decrease, an electric hand appears to oppose this prisoner, and in this way a cap is created. electric .
Adaptations can help organisms reproduce and continue living in different conditions
