Answer: :)
1.) The Doppler effect is, the change in sound or light that occurs whenever there is motion between the source and its observer. The siren of the fire engine has a lower pitch as it moves away because the waves are now spread out causing a lower frequency and a lower pitch.
2.) Wave frequency is related to wave energy. Since all that waves really are is traveling energy, the more energy in a wave, the higher its frequency. The lower the frequency is, the less energy in the wave.

C. Targets
Explanation:
Because the Ad for the theme park effectively caught Raquel's attention, a businessperson would say that the ad accurately targeted Raquel. Marketers use specific colors, themes, designs, songs, etc to target a specific audience.
Answer:
For the force due to electromagnetism we use Coulomb’s inverse square law:
F=keq1q2r2
(where F is the electrostatic force, q1 & q2 are the two charges, r is the distance between them, and Coulomb’s Constant ke=14πϵ0=8.99×109Nm2C−2, where ϵ0 is the permittivity of free space)
r=keq1q2F−−−−−√
r=8.99×109Nm2C−2−1.60×10−19C×−1.60×10−19C1.0N−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−√
r=1.52×10−14m
