I think this is the answer:
<span>Matter can change its state because of the pressure and/or the temperature.</span>
Answer:
-True - True - true - false -false - false
Explanation:
- True The flow depends only on the charge into the surface, not on the relative position
- True The two vectors are radial, so their relative direction do not changes
- True It just depends on the charge inside
- False, it only depends on the charge, not on the form from the integration surface
- False, because if it has a load inside it can be considered in the center, but if the load is outside the flow lines change direction with respect to the surface
- False The flow depends only on the load inside, not on its position
Answer:
= 54,000 Joules or 54 kJ
Explanation:
Electrical energy is given by the formula;
E = VIt; where V is the potential difference in volts, I is the current and t is the time in seconds.
Therefore;
Electrical energy = 120 V × 0.50 A × 15 ×60 seconds
= 54,000 Joules
Thus; the electrical energy is 54,000 joules or 54 kJ
