Final answer:
Electron flow is from a negatively charged object to ground, while conventional current flow is in the opposite direction. The energy can be calculated using the formula Energy = Charge × Voltage. In this case, the energy is 18 joules.
Step-by-step explanation:
To specify the direction of electron flow from a charged object to ground, we need to understand that electrons flow from a negatively charged object to a positively charged object. So, if the charged object has a negative charge, the direction of electron flow is from the object toward the ground. On the other hand, if the object has a positive charge, the direction of electron flow is from the ground toward the object.
Electron flow and conventional current flow are different concepts. Electron flow refers to the movement of electrons in a conductor, where electrons flow from the negative terminal of a voltage source to the positive terminal. On the other hand, conventional current flow is the opposite direction of electron flow. It assumes that current flows from the positive terminal to the negative terminal of a voltage source.
To calculate the energy, we can use the formula:
Energy = Charge (coulombs) × Voltage (volts)
Plugging in the given values, we get:
Energy = 6 coulombs × 3 volts = 18 joules
