Answer:
B. Planets orbit a star, while moons orbit a planet
Explanation:
Every planet must orbit a star, like how the Earth orbits the Sun (the star of our solar system). Our moon orbits Earth. On other planets, there can be dozens of moons orbiting it.
Answer:
c. As the thread is stretched, the coating thins and its resistance increases; as the thread is relaxed, the coating returns nearly to its original state.
Explanation:
This is in line with the result as shown in the data.
Stretching causes the coating to thin which in turn increases the resistance of the thread (conduction drops) releasing it backs returns the thread to nearly its initial values, but due to the strain already in the thread it does not return to its original values.
No. For one thing, when it comes, it flows too fast to catch it and store it. And second, you never know WHERE to set up your equipment.
Both bulbs in a series have the same current flowing through them. The bulb with the higher resistance will have a greater voltage drop across it, resulting in greater power dissipation and brightness. Both bulbs are connected in parallel and have the same voltage across them. (This most likely didn’t answer your question but I hope it was helpful in anyway.)
