the agency that is not under the direction of the departement of homeland security is : B. federal bureau of invetigation
They techincally had a diffferent jurisdiction. The federal bureau of Investigation only focus itself on domestic matter, while the homeland security also took care of the country's interest in other nations
The agency not under the Department of Homeland Security is the Federal Bureau of Investigation (FBI), which operates independently under the Department of Justice. DHS includes agencies such as FEMA, the Coast Guard, and the Secret Service. The FBI's primary focus is domestic law enforcement, differing from the mission of DHS.

Jawaban : 150 NPenjelasan:Diketahui: - Muatan A (qA) = 3 x 10⁻⁸ C- Muatan B (qB) = 6 x 10⁻⁸ C- Muatan C (qC) = 2 x 10⁻⁸ C- Jarak AB (rAB) = 3 cm = 0.03 m- Jarak BC (rBC) = 6 cm = 0.06 m- Konstanta Coulomb (k) = 9 x 10⁹ Nm²/C² (nilai standar)- Gaya coulomb antara A dan B [tex]f = k \frac{ |q1.q2| }{ {r}^{2} } [/tex]maka : [tex] f_{ab} = k \frac{ | q_{a}.q_{b} | }{ {r}^{2} _{ab} } = 9 \times {10}^{9} \\ \frac{ |(3 \times {10}^{ - 8})(6 \times {10}^{ - 8}) | }{0. {03}^{2} } = 180n[/tex]*Muatan a da b positif maka, gaya ini tolak-menolak- Gaya coulomb antara b dan c [tex]f_{ab} = k \frac{ | q_{b}.q_{c} | }{ {r}^{2} _{bc} } = 9 \times {10}^{9} \\ \frac{ |(6 \times {10}^{ - 8})(2 \times {10}^{ - 8}) | }{0. {06}^{2} } = 30n[/tex]*Muatan b dan c sama dengan sebelumnya yaitu positif maka, gaya nya tetap tolak-menolak- Total gaya coulomb pada muatan BGaya total pada muatan B adalah resultan dari [tex] f_{ab} [/tex]dan [tex] f_{bc}[/tex]. Karena arah gaya berlawanan, kita kurangi:[tex]f_{total} = f_{ab} - f_{bc} = 180n - 30n \: = 150n[/tex]Kesimpulan :Besarnya gaya Coulomb yang dialami oleh muatan di titik B adalah 150 N, dengan arah ke kanan (karena gaya tolak-menolak dari A lebih besar daripada gaya tolak-menolak dari C).
