Here are the answers and explanations for the questions you provided:**11. The correct answer is (c) 700 joule.*** **Explanation:** The energy required to move a charge through a potential difference is given by the formula: * Energy (E) = Charge (Q) * Potential Difference (V) * In this case, E = 70 Coulombs * 10 Volts = 700 Joules**12. The correct answer is (b) 20 Coulomb.*** **Explanation:** We can use the same formula as above, but rearrange it to solve for charge: * Charge (Q) = Energy (E) / Potential Difference (V) * Q = 180 Joules / 9 Volts = 20 Coulombs**13. The correct answer is (d) arus listrik berkurang.*** **Explanation:** The relationship between voltage, current, and resistance is described by Ohm's Law: * Voltage (V) = Current (I) * Resistance (R) * If the voltage decreases, and the resistance remains constant, the current must also decrease.**14. The correct answer is (d) 2 dan 4.*** **Explanation:** * **2. Joule/Coulomb:** This is the definition of a Volt (V). One Volt is equal to one Joule of energy per Coulomb of charge. * **4. Volt:** This is the standard unit of electrical potential difference.**15. The correct answer is (a) 40 volt.*** **Explanation:** Using the energy formula again, we can solve for the potential difference: * Potential Difference (V) = Energy (E) / Charge (Q) * V = 2000 Joules / 50 Coulombs = 40 Volts**16. The correct answer is (b) 7200 joule.*** **Explanation:** * First, calculate the power using the formula: Power (P) = Voltage (V) * Current (I) * P = 120 Volts * 0.5 Amps = 60 Watts * Convert the time to seconds: 20 minutes * 60 seconds/minute = 1200 seconds * Finally, calculate the energy using the formula: Energy (E) = Power (P) * Time (t) * E = 60 Watts * 1200 seconds = 72000 Joules
