C) The change of velocity over time
Answer:
20 Ω
Explanation:
Voltage, current, and resistance are related by Ohm's law:
V = IR
40 V = (4 A) R
R = 10 Ω
The total resistance of the circuit is 10 Ω.
Resistors in parallel have a total resistance of:
1/R = 1/R₁ + 1/R₂
1 / (10 Ω) = 1 / (20 Ω) + 1/R₂
R₂ = 20 Ω
The correct answer is "True."
Further Explanation:
When a person first sees someone they are interested in they may have feelings of infatuation. When a person feels this they may believe it is love, but it is a significant level of the dopamine and norepinephrine that is being released into the brain.
After a while, when the infatuation subsides, the person may not have the same feelings as before since the levels have subsided. These substances control several emotions in the brain such as cravings for food, desires, and even a person's motivation.

Elastic energy is potential energy and mechanical energy is kinetic energy.
Many times, elastic energy is a consequence of mechanical energy. When energy is transferred to an object through mechanical energy, it can often displace or deform the object. This stored energy because of the deformation is called elastic energy.
Answer:
It was most likely static electricity
Explanation:
Static electricity comes down to the interactive force between electrical charges.
So because your computer charger has electricity the foil is a conductor so the sparks were most likely static electricity
